Evidence of medium response to hard probes using correlations of Z bosons with hadrons in heavy ion collisions
V. Chekhovsky, A. Hayrapetyan, V. Makarenko, A. Tumasyan et autres
The first measurement of pseudorapidity and azimuthal angle distributions relative to the momentum vector of a Z boson for low transverse momentum (𝑝T) charged hadrons in lead-lead (PbPb) collisions is presented. By studying the hadrons produced in an event with a high-𝑝$_T$ …
