title: "$\Delta y_{ch,Z}$ in PbPb 0-90% for $2 &lt; p_T &lt; 4$ GeV" of "Evidence of medium response to hard probes using correlations of Z bosons with hadrons in heavy ion collisions"

description: The $\Delta y_{ch,Z}$ spectra for events with Z boson $p_{T}^Z &gt; 40$ GeV and charged-hadrons with $2
description: The first measurement charged hadron pseudorapidity and azimuthal angle distributions at low transverse momentum ($p_\mathrm{T}$) relative to the momentum vector of a $Z$ boson in lead-lead (\PbPb) collisions at a nucleon-nucleon center-of-mass energy $\sqrt{s_{NN}} = 5.02$ TeV is presented. By studying the hadrons produced opposite to the $Z$ boson, the analysis probes parton-medium interactions, including modifications to parton showers and medium response. Utilizing PbPb data from 2018 with an integrated luminosity of $1.67 \pm 0.03$ nb$^{-1}$ and proton-proton (pp) data from 2017 with $301 \pm 6$ pb$^{-1}$, the analysis examines the distributions in bins of charged-hadron $p_\mathrm{T}$. The analysis focuses on events containing at least one $Z$ boson with $40 &lt; p_\mathrm{T} &lt; 350$ GeV. A significant modification in the azimuthal angle and pseudorapidity distributions for charged hadrons in the range $1 &lt; p_\mathrm{T} &lt; 2$ GeV in PbPb collisions is observed when compared to reference measurements from pp collisions. The results are consistent with expectations from phenomenological models that include medium recoil, where the energy lost by the hard parton is transferred to the medium, and the medium-hole effect, which describes regions in the quark-gluon plasma depleted of energy due to parton-medium scattering. The data provide new information about the correlation between hard and soft particles in heavy ion collisions, which can be used to test predictions of various jet quenching models. Based on comparisons of PbPb data with pp references and predictions from theoretical models, this Letter presents the first evidence of medium-recoil and medium-hole effects caused by a hard probe.

title: "Figure 2-1" of "Observation of nuclear modification of energy-energy correlators inside jets in heavy ion collisions"

description: The energy-energy correlator distributions constructed with charged particles with $p_{\mathrm{T}} &gt; 1$ GeV for energy weight $n=1$ and jet $p_{\mathrm{T}}$ selection $120 &lt; p_{\mathrm{T,jet}} &lt; 140$ GeV. The results are shown for different centrality bins in PbPb collisions and for pp collisions.
description: Energy-energy correlators are constructed by averaging the number of charged particle pairs within jets, weighted by the product of their transverse momenta, as a function of the angular separation of the particles within a pair. They are sensitive to a multitude of perturbative and nonperturbative quantum chromodynamics phenomena in high-energy particle collisions. Using lead-lead data recorded with the CMS detector, energy-energy correlators inside high transverse momentum jets are measured in heavy ion collisions for the first time. The data are obtained at a nucleon-nucleon center-of-mass energy of 5.02 TeV and correspond to an integrated luminosity of $1.70\,\mathrm{nb}^{-1}$. A similar analysis is done for proton-proton collisions at the same center-of-mass energy to establish a reference. The ratio of lead-lead to proton-proton energy-energy correlators reveals significant jet substructure modifications in the quark-gluon plasma. The results are compared to different models that incorporate either color coherence or medium response effects, where the two effects predict similar substructure modifications.
