2026-07-072026-07-07http://salesiana.dossiersoluciones.com/handle/123456789/41133We present a study of event-by-event fluctuations of transverse momentum in $π^{+}\p$ and $\K^{+}\p$ collisions at 250 GeV/$c$ and the corresponding PYTHIA Monte Carlo results for $π^{+}\p$ collisions. The dependence of $Φ_{p_{t}}$ on event and particle variables are investigated in detail. We find that $Φ_{p_t}$ 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 $Φ_{p_{t}}$.4 pages, 5 figure (in epsi) talk given at XXXI International Symposium on Multiparticle Dynamics, Sep. 1-7, 2001, Datong China URL http://ismd31.ccnu.edu.cn/High Energy Physics - Phenomenologytext
