25. Probing nuclear symmetry energy with structures and reactions of heavy nuclei

The initial stages and nuclear structure in heavy-ion collisions

Oral

Neutron-rich matter exists naturally in neutron stars and neutron skins of heavy nuclei. It can also be created during mergers of neutron stars in space and heavy-ion collisions in terrestrial laboratories. The Equation of State (EOS) of such matter is still very poorly known but has broad impacts on many interesting issues in both astrophysics and nuclear physics. In particular, nuclear...

182. Dimuon production from photon fusion in hadronic Pb+Pb collisions with the ATLAS detector

The initial stages and nuclear structure in heavy-ion collisions

Oral

Measurements of muon pairs produced via two-photon scattering processes in hadronic (i.e. Non-UPC) Pb+Pb collisions are also presented. These non-UPC measurements provide a novel test of strong-field QED and may be a potentially sensitive electromagnetic probe of the quark-gluon plasma. These measurements include the dependence of the cross-section and angular correlation on the...

111. Heavy flavor physics at the sPHENIX experiment

Xuan Li (Los Alamos National Laboratory)

The initial stages and nuclear structure in heavy-ion collisions

Oral

In spring 2023, the sPHENIX detector at BNL’s Relativistic Heavy Ion Collider (RHIC) will begin measuring a suite of unique heavy flavor and quarkonia observables with unprecedented statistics and kinematic reach at the RHIC energies using combined electromagnetic and hadronic calorimeters and high precision tracking detectors. A Monolithic Active Pixel Sensor (MAPS)-based vertex detector...

196. Measurements of jet substructure in p+p and jet-event activity correlations in p+Au collisions at √sNN = 200 GeV at STAR

David Stewart (Wayne State University)

The initial stages and nuclear structure in heavy-ion collisions

Oral

In vacuum, a highly virtual parton fragments into a collimated spray of hadrons—known as a jet. Jets are useful in studying both perturbative and non-perturbative regimes of QCD. In p+p collisions, jet substructure observables are used to study the QCD evolutions and hadronization. In addition, measurements of the event activity dependence of jet properties in p+A collisions can provide new...

121. Open heavy-flavour and quarkonia production at LHCb

Jianqiao Wang (Tsinghua University (CN))

21/06/2023, 15:20

The initial stages and nuclear structure in heavy-ion collisions

Oral

Charm and bottom quark production is an important experimental observable that sheds light on the heavy quark interaction with the nuclear medium. With high statistics datasets, tracking and PID at very low transverse momentum, and excellent vertexing capabilities, LHCb performs precision measurements of a rich set of heavy flavor hadrons. These capabilities allow for precise studies of...
