Description

Measurements of long-range two-particle correlations have long provided critical insights into the properties of the matter created in heavy-ion collisions.
I will present results on long-range two-particle correlations for different charged particles multiplicities in pp at $\sqrt{s}=13\mathrm{T}\mathrm{e}\mathrm{V}$ and in p-Pb collisions at $\sqrt{s_{\mathrm{N}\mathrm{N}}}=5.02\mathrm{T}\mathrm{e}\mathrm{V}$.
These measurements utilize the Forward Multiplicity Detector (FMD), which allows for unprecedented $\mathrm{\Delta }\eta$ ranges to be explored (up to $\mathrm{\Delta }\eta \sim 8$).
We will compare such measurements to predictions from the relativistic hydro model calculation that supposes the QGP and Monte Carlo generators, which helps us to understand the contribution from non-QGP-like processes in an unexplored kinematic regime.
