Study of charged-particle multiplicity fluctuations in pp collisions with Monte Carlo event generators at the LHC

Proton–Proton (pp) collisions at the Large Hadron Collider (LHC) are simulated in order to study events with a high local density of charged particles produced in narrow pseudorapidty windows of Δη = 0.1, 0.2, and 0.5. The pp collisions are generated at center of mass energies of s = 2.36, 7, 8, and...

description Proton–Proton (pp) collisions at the Large Hadron Collider (LHC) are simulated in order to study events with a high local density of charged particles produced in narrow pseudorapidty windows of Δη = 0.1, 0.2, and 0.5. The pp collisions are generated at center of mass energies of s = 2.36, 7, 8, and 13 TeV, i.e., the energies at which the LHC has operated so far, using PYTHIA and HERWIG event generators. We have also studied the average of the maximum charged-particle density versus the event multiplicity for all events, using the different pseudorapidity windows. This study prepares for the multi-particle production background expected in a future search for anomalous high-density multiplicity fluctuations using the LHC data.
