Two-particle correlations in pp collisions at 13 TeV measured with CMS

Results on two-particle angular correlations for charged particles emitted in $pp$ collisions at a center-of-mass energy of 13 TeV are presented as a function of charged-particle multiplicity and transverse momentum $(p_{T})$. In high$-$multiplicity events, a long-range $(\mid \eta \mid> 2.0)$, n...

description Results on two-particle angular correlations for charged particles emitted in $pp$ collisions at a center-of-mass energy of 13 TeV are presented as a function of charged-particle multiplicity and transverse momentum $(p_{T})$. In high$-$multiplicity events, a long-range $(\mid \eta \mid> 2.0)$, near-side $(\Delta \phi = 0)$ structure emerges in the two-particle $\Delta\eta - \Delta\phi $ correlation functions. The overall correlation strength is similar to that found in earlier $pp$ data at 7 TeV, but is measured up to much higher multiplicity values. A detailed study in $pp$ collisions at 7 TeV of the second-order $(v_{2})$ % and third-order $(v_{3})$ azimuthal anisotropy harmonics of charged particles, $K_{S}^{0}$ and $\Lambda/\bar{\Lambda}$ particles are extracted from long-range two-particle correlations as a function of particle multiplicity and transverse momentum and are also compared with values obtained in pPb and PbPb collisions at similar multiplicities.
