Large area attenuated total reflectance-Fourier transform infrared spectroscopy (LAATR-FTIR) is introduced as a novel technique for detecting small microplastics (MPs) down to 1.3 μm. Two different LAATR units, one with a zinc selenide (ZnSe) and one with a germanium (Ge) crystal, were used to detect reference MPs < 20 μm, and MPs in marine water s...

More than two decades ago, the numerical instabilities of particle clustering and non-physical fractures encountered in the simulations of typical elastic dynamics problems using updated Lagrangian smoothed particle hydrodynamics (ULSPH) was identified as tensile instability.

We present measurements of two-particle angular correlations of charged particles emitted in high-energy collisions using data collected by the ALEPH detector at LEP between 1992 to 2000. The correlation functions are measured over a wide range of pseudorapidity and azimuthal angle as a function of charged particle multiplicity. Previous measuremen...

One of the findings of the LHC heavy ion program is the observation of stronger suppression of the excited quarkonium states compared to the ground states in lead-lead (PbPb) and proton-lead (pPb) collisions. Such differences among the states may imply dissociation effects occurring at late stages, after the evolution of heavy quark pairs into well...

The ATLAS collaboration has recently observed that the variance of the transverse momentum per particle ([pt]), when measured as a function of the collision multiplicity (Nch) in Pb+Pb collisions, decreases by a factor 2 for the largest values of Nch, corresponding to ultra-central collisions. We show that this phenomenon is naturally explained by...

In this contribution, a selection of the experimental re...

As the Advanced CCD Imaging Spectrometer (ACIS) on the Chandra X-ray Observatory completes a quarter century of on orbit operations, it continues to perform well and produce spectacular scientific results. The response of ACIS has evolved over the lifetime of the observatory due to radiation damage, molecular contamination, changing particle enviro...

One of the most studied phenomena in heavy-ion physics is the collective emission of particles. Historically, the observation of collectivity in nucleus-nucleus collisions has been viewed as proof of the creation of a strongly interacting medium, as neither independent particle emission nor hadronic interactions alone could account for measurements...

Among the most iconic results of Run-1 and Run-2 of the LHC is the observation of enhanced production of (multi-)strange to non-strange particles, gradually rising from low-multiplicity to high-multiplicity pp or p–Pb collisions and reaching values close to those measured in peripheral Pb–Pb collisions [1]. The observed behaviour cannot be quantita...

We present a unique signal of medium response to jet quenching: the enhancement of baryon-to-meson ratios for associated particles at intermediate transverse momentum around the triggered quenched jets. Since the lost energy from the jets can diffuse to large angles, we expect that such baryon-to-meson enhancement is stronger for larger distance wi...

JRC C.4 participates in the H2020 project LEON-T which aims to increase knowledge about particle, microplastic, and noise emissions from tires—and their associated effects on public health and well-being.

We propose a scalar dark matter model featuring a hidden gauge symmetry, denoted as U(1)_X, with two complex scalars, Phi and S. In this framework, Phi spontaneously breaks the U(1)_X gauge symmetry, while S serves as a viable dark matter candidate. Particularly, the kinetic and direct mixings between the U(1)_X and U(1)_Y gauge groups provide a po...

This contribution discusses baryon-rich matter in the context of recent astrophysical observations of neutron stars (NSs) and the structure of the equation of state that arises from these observations. We show that, generating an ensemble of equations of state that fulfill multimessenger constraints, the speed of sound and trace anomaly can reach t...

Strangeness enhancement has long been considered a signature of quark-gluon plasma formation in heavy-ion collisions. Recently, strangeness enhancement has also been observed in small systems at the Large Hadron Collider (LHC), but the underlying physics is not yet fully understood. This motivates us to study of strange hadron production in small s...

The utilization of Z bosons, which are insensitive to the strong interaction, can constrain the initial energy, direction, and flavor of recoiling partons prior to their interaction with the quark-gluon plasma. This investigation focuses on charged particle yields in Z boson events, enabling a detailed exploration of in-medium modifications in both...

The PHENIX experiment at RHIC has a unique large rapidity coverage (1.2 < |y| < 2.2) for heavy flavor studies in heavy-ion collisions. This kinematic region has a smaller particle density and may undergo different nuclear effects before and after the hard process when compared to mid-rapidity production. The latest PHENIX runs contain a large data...

Recent measurements of femtoscopic correlations at NA61/SHINE unravel that the shape of the particle emitting source is not Gaussian.

Both π⁺ and KS⁰ show negative v1 slope at low pT (pT < 0.6 GeV/c). Collision energy dependence of v1 slope and pT -integrated v2 for π±, KS⁰, and Λ are als...

It is hardly controversial that laypeople have little-to-no knowledge concerning the actual meaning of such specialist terms as “boson” or “sarcoidosis” (at best, they can say that sarcoidosis is a disease and boson is some particle.) It has been convincingly shown (Burge, 1979, 1986, 1988, 1989, 2003; Putnam, 1973, 1975, 1978) that not the communi...

Particle correlations are a powerful tool to study the properties of the bulk nuclear matter produced in relativistic heavy ion collisions. The momentum correlations between identical particles originating from the same particleemitting source, referred to as the Bose-Einstein correlations, measure scales that are related to the geometrical size of...

In this study, we utilize the SMASH transport model to explore the generation of global angular momentum in heavy-ion collisions.

The double-slit experiment is a cornerstone in quantum mechanics, illustrating the dual nature of particles such as electrons and photons, which can behave both as waves and particles. This phenomenon can be explored in detail using the principles of wave function, projection operators, and Heisenberg's uncertainty principle.

To adequately describe the motion of a particle in a central force field, one has to specify the apsidal angle (α). The particle's trajectory can only be truly periodic (closed), if α/π is a rational number. For example, if F ∼ 1/r^2 then α = π, and the trajectory is an ellipse. This is the simplest case when the trajectory equation (Binet's equati...

Slow relaxation and heterogeneous dynamics are characteristic features of glasses. The presence of glassy dynamics in nonequilibrium systems, such as active matter, is of significant interest due to its implications for living systems and material science. In this study, we use dense suspensions of self-propelled Janus particles moving on a substra...

Majorana fermions are a fascinating class of particles with unique and intriguing properties: they are their own antiparticles, as first theorized by the Italian physicist Ettore Majorana in 1937.

Inspired by recent findings that semi-inclusive detections of heavy hadrons exhibit fair stabilization patterns in high-energy resummed distributions against (missing) higher-order corrections, we review and extend our studies on the hadroproduction of light and heavy hadrons tagged in forward and far-forward rapidity ranges. We analyze the NLL/NLO...

The flavor structure of quarks and leptons is not yet fully understood, but it hints a more fundamental theory of nonuniversal generations. We therefore propose a simple extension of the Standard Model by flipping (i.e., enlarging) the hypercharge U ( 1 ) Y to U ( 1 ) X ⊗ U ( 1 ) N for which both X and N depend on generations of both quark and lept...

In 2002, Chowdhury et al. introduced a simplified model aimed at depicting the dynamics of single-lane unidirectional ant traffic.

It is shown that the Schrödinger equation can be solved in this full-tensor format but that by using a low-rank tensor decomposition, in particular...

Although axionlike particles (ALPs) are popular dark matter candidates, their mass generation mechanisms as well as cosmic thermal evolutions are unclear. In this paper, we propose a new mass generation mechanism of an ALP during the electroweak phase transition in the presence of the type-II seesaw mechanism. In this scenario, the ALP gets mass un...

We perform canonical quantization of the single-component, spin-zero field that was introduced by Dirac in 1971 and recently suggested as a candidate for dark matter by Bogomolny. The massive and massless cases are treated separately. Since in the massive case only positive-frequency modes are normalizable and regarded as physical, the mode expansi...

It is known that the masses of all particles (besides photon and neutrino) follow the law of energy (E = mc 2): This was demonstrated to be the case for the electron/positron. The mass of the photon and the neutrino do not depend on velocity, which means that the fundamental building blocks of particles must be electrons and positrons!. The photon...

In this study, we explore the characteristics of higgsino-dominated dark matter (DM) within the semi-constrained Next-to-Minimal Supersymmetric Standard Model (scNMSSM), covering a mass range from hundreds of GeV to several TeV. We carefully analyzed the parameter space under existing theoretical and experimental constraints to confirm the viabilit...

Supercooled liquids are sometimes described as being composed of a mosaic of patches that may be listed in a `library', each one having some form of non-periodic order.

Half a century later, two experiments at CERN confirmed that this mechanism is realized in nature. On April 8th, we received the sad news of the p...

We show how to derive an effective nonlinear dynamics, described by the Hartree-Fock equations, for fermionic quantum particles confined to a two-dimensional box and in presence of an external, uniform magnetic field. The derivation invokes the Dirac-Frenkel principle. We discuss the validity of this effective description with respect to the many-b...

The spontaneous breakdown of an approximate symmetry implies that the spectrum of the theory contains approximately massless particles. The hidden symmetry very strongly constrains their masses. A numerical evaluation of these constraints on the lattice would allow a more precise determination of the quark mass ratios mu:md:ms and thereby reduce so...
