Description
We study the first-order Fox-Wolfram moment $H_1^T$ in relativistic heavy-ion collisions, where jet productions in p + p are simulated within a Monte Carlo event generator SHERPA 2.2.11, and the jet propagation in medium with the Linear Boltzmann Transport (LBT) model. Because of jet quenching effect, a suppression of the distribution at small $H_1^T$ region and an enhancement at large $H_1^T$ region are observed for 2-jet events in Pb + Pb collisions as compared to their p + p reference, whereas for the $\geq 3$ jets events, we see the suppressions both in the small and large $H_1^T$ regions. The nuclear modification factor for $H_1^T$ of $\geq 2$ jet events is also presented, which is smaller than unity with the small $H_1^T$ but larger than one at large $H_1^T$. The underlying reason for this novel behavior is also discussed.
