Event-by-Event Fluctuations of Transverse Momentum in Elementary Collisions at 250 GeV/$c$

Abstract

We present a study of event-by-event fluctuations of transverse momentum in ${\pi }^{+}\text{p}$ and ${\text{K}}^{+}\text{p}$ collisions at 250 GeV/$c$ and the corresponding PYTHIA Monte Carlo results for ${\pi }^{+}\text{p}$ collisions. The dependence of ${\Phi }_{p_t}$ on event and particle variables are investigated in detail. We find that ${\Phi }_{p_t}$ are all negative for different average transverse momentum per event sample. The $<p_t{>}_N\sim N$ correlation may not be the only origin of ${\Phi }_{p_t}$.
