Symmetric cumulants as a probe of the proton substructure at LHC energies

We present a systematic study of the normalized symmetric cumulants, NSC(n,m), at the eccentricity level in proton-proton interactions at \(\sqrt s\!=\! 13\) TeV within a wounded hot spot approach. We focus our attention on the influence of spatial correlations between the proton constituents, in ou...

Description
Summary:We present a systematic study of the normalized symmetric cumulants, NSC(n,m), at the eccentricity level in proton-proton interactions at \(\sqrt s\!=\! 13\) TeV within a wounded hot spot approach. We focus our attention on the influence of spatial correlations between the proton constituents, in our case gluonic hot spots, on this observable. We notice that the presence of short-range repulsive correlations between the hot spots systematically decreases the values of NSC(2,3) and NSC(2,4) in mid-to-ultra central collisions while increases them in peripheral interactions. In the case of NSC(2,3) we find that, as suggested by data, an anti-correlation of \(\varepsilon_2\) and \(\varepsilon_3\) in ultra-central collisions, i.e. NSC(2,3)\(
