论文摘要
与孤立光子相关的喷气器是研究重型离子碰撞中喷射淬火的有前途的通道，因为光子没有强烈相互作用，因此会限制初始硬散射的$ q^2 $。我们介绍了在$ \ sqrt {s _ {\ text {nn}}} $ = 5.02 TEV中，Alice Collaboration在$ \ sqrt {s _ {s _ {s _ {s _ {s _ {s _ {s _ {s _ {s _ {我们研究了20 GEV/$ C $以上的隔离光子与10 GEV/$ C $高于10 GEV/$ C $的隔离光子的相关性，并用抗$ k_ \ text {t} $算法重建。相关探测最低的JET $ p_ \ text {t} $范围在LHC Energies曾经测量过，并且在较低的$ p_ \ text {t} $ engime中期望QGP引起的更大的修改。
Jets correlated with isolated photons are a promising channel to study jet quenching in heavy-ion collisions, as photons do not interact strongly and therefore constrain the $Q^2$ of the initial hard scattering. We present the isolated photon-jet correlations measured in Pb--Pb collisions at $\sqrt{s_{\text{NN}}}$ = 5.02 TeV by the ALICE collaboration. We study correlations of isolated photons above 20 GeV/$c$ with charged-particle jets above 10 GeV/$c$, reconstructed with the anti-$k_\text{T}$ algorithm. The correlations probe the lowest jet $p_\text{T}$ range ever measured at LHC energies, and larger modifications due to the QGP are expected in the lower $p_\text{T}$ regime.
