The shape of differential radial flow , not its zero-crossing, carries physical information
Somadutta Bhatta, Aman Dimri, Jiangyong Jia
Radial flow, a key collective phenomenon in heavy-ion collisions, manifests itself through event-by-event fluctuations of transverse-momentum () spectra. The $p_{\m…

Impact of the radial profile of atomic nuclei on observables in high-energy collisions
Zhengxi Yan, Jun Xu, Jiangyong Jia
In heavy-ion phenomenology, the nucleon density distribution in colliding nuclei is commonly described by a two-parameter Woods-Saxon (WS) distribution. However, this approach over…

Transverse momentum fluctuation in ultra-central Pb+Pb collision at the LHC
Rupam Samanta, Somadutta Bhatta, Jiangyon Jia +2
The ATLAS collaboration has recently observed that the variance of the transverse momentum per particle (), when measured as a function of the collision multiplicity ($N_{…
