论文摘要
从$ \ sqrt {s} = 13 $ tev的质子质子碰撞中的cern LHC的爱丽丝实验中提出了最近的JET测量结果，重点是包含和迷人的喷气机的子结构结果。为各种喷气分辨率参数显示了修饰的喷气动量分数（$ z_g $），以及$ z_g $，修饰的分裂半径（$θ_g$）以及软滴的数量（$ n _ {\ rm SD} $）的数量（\ rm sd} $），包括包含的和charmed chunmed chunmed chunmed chunmed chunmed chunded purged-Particle-Particle-Particle-Particle Particle Jets。还提出了重型瓶喷头中死锥的第一个直接测量。此外，显示了Charmed D $^0 $介子和$λ_\ Mathrm {C}^+$ baryons的平行动量分数。除了作为重型离子碰撞中喷气结构修饰测量值的参考外，这些结果还为QCD Parton淋浴性能和风味依赖性碎片过程提供了新的见解。
A selection of recent jet measurements are presented from the ALICE experiment at the CERN LHC in proton-proton collisions at $\sqrt{s}=13$ TeV, focusing on substructure results for inclusive and charmed jets. The groomed jet momentum fractions ($z_g$) of inclusive full jets are shown for various jet resolution parameters, and $z_g$, the groomed splitting radius ($θ_g$) as well as the number of soft drops ($n_{\rm SD}$) of inclusive and charmed charged-particle jets are compared. The first direct measurement of the dead cone in heavy-flavor jets is also presented. Furthermore, the parallel momentum fractions of charmed D$^0$ mesons and $Λ_\mathrm{c}^+$ baryons are shown. Besides serving as a reference for jet structure modification measurements in heavy-ion collisions, these results provide new insight to QCD parton shower properties and flavor-dependent fragmentation processes.
