Abstract

Korelacije čestica koristan su alat za analizu mehanizama proizvodnje čestica te njihovih kolektivnih ponašanja u visokoenergetskim sudarima. Prijašnja mjerenja ukazala su na pojavu grebenastih struktura u korelacijskim funkcijama koje bi mogle biti indikator za pojavu kvarkovsko-gluonske plazme. Nastanak takvog stanja materije očekivan je u sudarima teških iona, no ne i u sudarima protona. S druge strane, grebenaste strukture pod određenim uvjetima se pojavljuju i u sudarima protona, što je zasad teorijski neobjašnjivo. U diplomskom radu reproducirati će se grebenasta struktura u sudarima protona i promotriti pod kojim se uvjetima pojavljuje najsličnija struktura u sudarima iona te će se usporediti varijable sudara u oba sustava.

Abstract (english)

Particle correlations are a useful tool for analysing the mechanisms of particle production and their collective behaviour in high energy collisions. Previous measurements have revealed the appearance of ridge-like structures in correlation functions that could indicate the existence of quark-gluon plasma. The creation of such a state is expected in heavy ion collisions, but not in proton collisions. On the other hand, under certain conditions ridge-like structures appear in proton collisions as well, which is still not theoretically explained. In this diploma thesis the ridge structure will be reproduced in proton collisions and it will be investigated under which conditions the most similar structure appears in heavy-ion collisions and variables in both systems will be compared.
