abstract
Hadron-hadron collisions at high energies are investigated in the Ultra-relativistic-Quantum-Molecular-Dynamics approach (UrQMD). This microscopic transport model is designed to study pp, pA and A+A collisions. It describes the phenomenology of hadronic interactions at low and intermediate energies ($\sqrt s <5$ GeV) in terms of interactions between known hadrons and their resonances. At high energies, $\sqrt s >5$ GeV, the excitation of color strings and their subsequent fragmentation into hadrons dominates the multiple production of particles in the UrQMD model. The model shows a fair overall agreement with a large body of experimental h-h data over a wide range of h-h center-of-mass energies. Hadronic reaction data with higher precision would be useful to support the use of the UrQMD model for relativistic heavy ion collisions.

The pion emission source in Au+Au collisions is tilted with magnitude decreasing rapidly as collision energy rises from 7.7 to 27 GeV, indicating departure from longitudinal boost invariance.
K*0/K yield ratios in central Au+Au collisions at BES energies are suppressed relative to peripheral collisions and thermal predictions, indicating hadronic rescattering that strengthens at lower energies.
First measurements of v_n (n=2-4) in 5.36 TeV O+O and Ne+Ne collisions show enhanced v2 in central neon collisions consistent with prolate nuclear deformation.
A hybrid freeze-out model combining transport dynamics and thermal cluster production is proposed for light nuclei in intermediate-energy heavy-ion collisions.
ATLAS measures charged-particle pseudorapidity density and mean transverse momentum in O+O and Ne+Ne collisions at 5.36 TeV as a function of centrality and eta.
Residual Coulomb and isospin effects produce charge-dependent splittings in identical-particle correlation functions, strongest at low kT, that modify fitted radii.
Bayesian posteriors from JETSCAPE jet-quenching model are largely compatible across centrality but exhibit shifts across beam energy and observable class, with varying ability to predict complementary datasets.
Lambda polarization in low-energy heavy-ion collisions depends on the equation of state in UrQMD simulations and arises from shear in the baryon current due to stopping.
REDTOP targets O(10^14) eta and O(10^12) eta-prime decays to probe four hidden sector portals and test CP/T invariance plus lepton universality.
UrQMD plus coalescence predicts measurable yields of hypernuclei such as 3_Lambda H, 4_Lambda H, Xi N and Xi NN in p+Au reactions at FAIR energies.
UrQMD model simulations of K* resonances in Ar+Sc collisions at SPS energies capture essential features but underpredict the strong suppression observed in central NA61/SHINE data.
Recent net-proton cumulant ratios from RHIC BES-II data are compared to non-critical models from Lattice QCD, HRG, hydrodynamics and UrQMD, with volume fluctuation effects noted at fixed-target energies.
