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_{…
Charm balance function in relativistic heavy-ion collisions
Tribhuban Parida, Piotr Bozek, Sandeep Chatterjee
We calculate the balance function for charm in relativistic heavy-ion collisions. The distribution of pairs of charm-anticharm quarks produced in hard processes in the early stages…
Non-Gaussian transverse momentum fluctuations from impact parameter fluctuations
Rupam Samanta, João Paulo Picchetti, Matthew Luzum +1
The transverse momentum per particle, , fluctuates event by event in ultrarelativistic nucleus-nucleus collisions, for a given multiplicity. These fluctuations are small and…
Relativistic second-order spin hydrodynamics: an entropy-current analysis
Rajesh Biswas, Asaad Daher, Arpan Das +2
We present a new derivation of Israel-Stewart-like relativistic second-order dissipative spin hydrodynamic equations using the entropy current approach. In our analysis, we conside…
Random model of flow decorrelation
Piotr Bozek, Hadi Mehrabpour
The collective flow generated in relativistic heavy-ion collisions fluctuates from event to event. The fluctuations lead to a decorrelation of flow vectors measured in separate bin…
Cumulants from fluctuating width of rapidity distribution
Michał Barej, Adam Bzdak
In relativistic heavy-ion collisions, the longitudinal fluctuations of the fireball density caused, e.g., by baryon stopping fluctuations result in event-by-event modifications of…
