Structure in the speed of sound: From neutron stars to heavy-ion collisions [PDF]

open access: yesPhysical Review C, 2023
From the observation of both heavy neutron stars and light ones with small radii, one anticipates a steep rise in the speed of sound of nuclear matter as a function of baryon density up to values close to the causal limit. A question follows whether such

Spin Alignment of Vector Mesons in Heavy-Ion Collisions. [PDF]

open access: yesPhysical Review Letters, 2022
Polarized quarks and antiquarks in high-energy heavy-ion collisions can lead to the spin alignment of vector mesons formed by quark coalescence. Using the relativistic spin Boltzmann equation for vector mesons derived from Kadanoff-Baym equations with an

Impact of Nuclear Deformation on Relativistic Heavy-Ion Collisions: Assessing Consistency in Nuclear Physics across Energy Scales. [PDF]

open access: yesPhysical Review Letters, 2021
In the hydrodynamic framework of heavy-ion collisions, elliptic flow v_{2} is sensitive to the quadrupole deformation β of the colliding ions. This enables one to test whether the established knowledge on the low-energy structure of nuclei is consistent ...

Exclusive dielectron production in ultraperipheral Pb+Pb collisions at s NN $$ \sqrt{s_{\textrm{NN}}} $$ = 5.02 TeV with ATLAS

open access: yesJournal of High Energy Physics, 2023
Exclusive production of dielectron pairs, γγ → e + e − , is studied using L int $$ {\mathcal{L}}_{\textrm{int}} $$ = 1.72 nb −1 of data from ultraperipheral collisions of lead nuclei at s NN $$ \sqrt{s_{\textrm{NN}}} $$ = 5.02 TeV recorded by the ATLAS ...

Heavy-ion fusion injector experiments [PDF]

open access: yesIl Nuovo Cimento A, 1993
We report on three experiments performed in connection with the 2MV electrostatic quadrupole (ESQ) injector under construction at Lawrence Berkeley Laboratory. Scaled experiments have been conducted to study possible beam emittance growth due to beam aberrations in an ESQ injector.

Measurement of beauty and charm production in pp collisions at s $$ \sqrt{s} $$ = 5.02 TeV via non-prompt and prompt D mesons

open access: yesJournal of High Energy Physics, 2021
The p T-differential production cross sections of prompt and non-prompt (produced in beauty-hadron decays) D mesons were measured by the ALICE experiment at midrapidity (| y | < 0.5) in proton-proton collisions at s $$ \sqrt{s} $$ = 5.02 TeV.

Novel scheme for parametrizing the chemical freeze-out surface in heavy ion collision experiments [PDF]

open access: yesPhysical Review D, 2019
We introduce a new prescription for obtaining the chemical freeze-out parameters in the heavy ion collision experiments using the hadron resonance gas model.

Centrality determination in heavy-ion collisions with the LHCb detector [PDF]

open access: yes, 2021
The centrality of heavy-ion collisions is directly related to the created medium in these interactions. A procedure to determine the centrality of collisions with the LHCb detector is implemented for lead-lead collisions at √s NN = 5 TeV and lead-neon ...
