Event-by-event mean pT fluctuations in pp and Pb–Pb collisions at the LHC

KARASU UYSAL, Ayben | ALICE Collaboration

Event-by-event fluctuations of the mean trans- verse momentum of charged particles produced in pp colli- sions at √s = 0.9, 2.76 and 7 TeV, and Pb–Pb collisions at √sNN = 2.76 TeV are studied as a function of the charged- particle multiplicity using the ALICE detector at the LHC. Dynamical fluctuations indicative of correlated particle emis- sion are observed in all systems. The results in pp collisions show little dependence on collision energy. The Monte Carlo event generators PYTHIA and PHOJET are in qualitative agreement with the data. Peripheral Pb–Pb data exhibit a sim- ilar multiplicity ...Daha fazlası

Relative particle yield fluctuations in Pb–Pb collisions at √sNN = 2.76 TeV

KARASU UYSAL, Ayben | ALICE Collaboration

First results on K/π, p/π and K/p fluctuations are obtained with the ALICE detector at the CERN LHC as a function of centrality in Pb–Pb collisions at √sNN = 2.76 TeV . The observable νdyn , which is defined in terms of the moments of particle multiplicity distributions, is used to quantify the magnitude of dynamical fluctuations of rela- tive particle yields and also provides insight into the corre- lation between particle pairs. This study is based on a novel experimental technique, called the Identity Method, which allows one to measure the moments of multiplicity distri- butions in case of ...Daha fazlası
