EPOS LHC: Test of collective hadronization with data measured at the CERN Large Hadron Collider
Mixed citation behavior. Most common role is background (60%).
abstract
EPOS is a Monte-Carlo event generator for minimum bias hadronic interactions, used for both heavy ion interactions and cosmic ray air shower simulations. Since the last public release in 2009, the LHC experiments have provided a number of very interesting data sets comprising minimum bias p-p, p-Pb and Pb-Pb interactions. We describe the changes required to the model to reproduce in detail the new data available from LHC and the consequences in the interpretation of these data. In particular we discuss the effect of the collective hadronization in p-p scattering. A different parametrization of flow has been introduced in the case of a small volume with high density of thermalized matter (core) reached in p-p compared to large volume produced in heavy ion collisions. Both parametrizations depend only on the geometry and the amount of secondary particles entering in the core and not on the beam mass or energy. The transition between the two flow regimes can be tested with p-Pb data. EPOS LHC is able to reproduce all minimum bias

Secondary cascades in the TAXN absorber produce a substantial millicharged particle flux that complements primary production and boosts FORMOSA signals by ~50% for m_χ below 0.1 GeV.
Ultraheavy nuclei have longer energy loss lengths at ≲300 EeV than lighter nuclei, allowing them to explain UHECRs above 100 EeV from sources like collapsars and neutron star mergers while predicting distinct shower maxima.
ATLAS measured charged-particle production in 9.62 TeV p-O collisions, yielding a fiducial pO cross section of 396 mb and extrapolated p-air inelastic cross section of 406 mb, with distributions an order of magnitude more precise than hadronic model differences.

The equilibrated core in O+O collisions overtakes the nonequilibrium corona above midrapidity multiplicity of about 20, yet corona contributions persist in central events, making pure hydrodynamics inadequate.
No evidence for charginos and neutralinos in R-parity violating Higgs-decay channels; masses 150-1100 GeV excluded at 95% CL assuming equal lepton branching fractions.

Simulations show non-flow two-particle cumulant distributions have high skewness and kurtosis while true elliptic flow distributions are closer to Gaussian with lower values.
The p_T dependence of the Ω/φ ratio in pp, p-Pb and Pb-Pb collisions is dominated by the discrete curvature of the strange-quark transverse-momentum spectrum extracted from φ data via quark-number scaling.
