- Micro-canonical hadron production in pp collisions (2003)
- We apply a microcanonical statistical model to investigate hadron production in pp collisions. The parameters of the model are the energy E and the volume V of the system, which we determine via fitting the average multiplicity of charged pions, protons and antiprotons in pp collisions at different collision energies. We then make predictions of mean multiplicities and mean transverse momenta of all identified hadrons. Our predictions on nonstrange hadrons are in good agreement with the data, the mean transverse momenta of strange hadron as well. However, the mean multiplicities of strange hadrons are overpredicted. This agrees with canonical and grandcanonical studies, where a strange suppression factor is needed. We also investigate the influence of event-by-event fluctuations of the E parameter.
- A micro-canonical description of hadron production in proton-proton collisions (2003)
- A micro-canonical treatment is used to study particle production in pp collisions. First this micro-canonical treatment is compared to some canonical ones. Then proton, antiproton and pion 4 pi multiplicities from proton-proton collisions at various center of mass energies are used to fix the micro-canonical parameters (E) and (V). The dependences of the micro-canonical parameters on the collision energy are parameterised for the further study of pp reactions with this micro-canonical treatment.
- The physics of EPOS (2013)
- We discuss recent developments of the EPOS hadronic interaction model, in particular concerning collective phenomena as implemented in EPOS 2.17, relevant for proton-proton, proton-nucleus, and nucleusnucleus collisions at very high energies.
- Production of pentaquark states in pp collisions within the microcanonical ensemble (2004)
- The microcanonical statistical approach is applied to study the production of pentaquark states in pp collisions. We predict the average multiplicity and average transverse momentum of Theta+(1540) and Xi(1860) and their antiparticles at different energies.
