This paper derives simple, necessary and sufficient inequalities that ensure nonlinear causality in viscous anisotropic hydrodynamics by analyzing characteristic velocities, thereby establishing the theory's regime of validity for describing the early-time dynamics of relativistic heavy-ion collisions.
This paper presents high-precision ALICE measurements of prompt charm hadron elliptic flow () in Pb-Pb and OO collisions at TeV, highlighting the first observation of baryon-meson splitting at intermediate and probing charm quark thermalization across systems of varying size.
Using a lattice Boltzmann-Uehling-Uhlenbeck transport model with a kinetic approach for light-cluster formation, this study demonstrates that explicitly including dynamical light-cluster degrees of freedom significantly modifies proton collective flows at beam energies below 600 A MeV and successfully reproduces the nucleon-number scaling of light nuclei flows, thereby highlighting the necessity of dynamical cluster treatment for interpreting heavy-ion collision data in this energy regime.
This paper analyzes the convergence of the hyperspherical adiabatic basis for the $ppp$ correlation function at energies beyond the correlation peak, demonstrating that including three-body states up to is essential for accurately describing the correlation tail and achieving excellent agreement with experimental data.
This paper presents a physics-informed neural-network framework that embeds the Balitsky-Kovchegov evolution equation to unbiasedly extract the nuclear dipole amplitude for Pb directly from experimental data, revealing a saturation scale consistent with geometric scaling and successfully predicting transverse-momentum ratios in various collision systems without system-dependent parameters.
This paper proposes a liquid Krypton Time Projection Chamber that utilizes the unique four-gamma tagging signature of double positron decay to achieve a virtually background-free search, with a small prototype capable of setting world-leading limits and a ton-scale detector reaching sensitivities of – years.
This paper reports the extraction of polarized photoproduction cross-sections for the proton, neutron, deuteron, and He by extrapolating electron scattering data from Jefferson Lab experiments to the real photon point, revealing that while proton results align with real photon data, the neutron and deuteron exhibit enhanced strength in the region that better supports isospin symmetry.
This paper presents the construction of the CROSS experiment's 4.9 kg Mo scintillating cryogenic calorimeter array at the Canfranc underground laboratory and reports Geant4-based simulations predicting a background level that enables world-leading sensitivity to neutrinoless double-beta decay within one year of data taking.
Using LHCb data from $pp$ and collisions at , this study presents the first measurements of the average transverse momentum of forward prompt charged particles, revealing a decreasing trend with pseudorapidity that supports collective behavior and aligns with hydrodynamic calculations while contradicting saturation models.
This study computes net-proton number fluctuations across nine collision energies using a hydrodynamic model incorporating critical fluctuations from the functional renormalization group, revealing that while low-order cumulant ratios show minimal deviation from non-critical baselines, higher-order ratios like exhibit a distinct non-monotonic energy dependence driven by the critical end point.
