• Direct photon production at low transverse momentum in proton-proton collisions at √s = 2.76 and 8 TeV 

  ALICE Collaboration (American Physical Society, 2019)

  Measurements of inclusive and direct photon production at midrapidity in pp collisions at √s=2.76 and 8 TeV are presented by the ALICE experiment at the LHC. The results are reported in transverse momentum ranges of 0.4<pT<10 ...

• Nonprompt direct-photon production in Au+Au collisions at √sNN = 200 GeV 

  PHENIX Collaboration (American Physical Society (APS), 2024)

  The measurement of the direct-photon spectrum from Au+Au collisions at √sNN=200 −−−√=200 GeV is presented by the PHENIX collaboration using the external-photon-conversion technique for 0\%--93\% central collisions in a ...

• Low-pT direct-photon production in Au+Au collisions at √sNN = 39 and 62.4 GeV 

  PHENIX Collaboration (American Physical Society (APS), 2023)

  The measurement of direct photons from Au+Au collisions at √sNN=39 and 62.4 GeV in the transverse-momentum range 0.4<3Gev/c is presented by the PHENIX collaboration at the BNLRelativistic Heavy Ion Collider. A significant ...

• Direct photon production in Pb–Pb collisions at √sNN = 2.76 TeV 

  ALICE Collaboration (Elsevier B.V., 2016)

  Direct photon production at mid-rapidity in Pb–Pb collisions at √sNN = 2.76 TeV was studied in the transverse momentum range 0.9 < pT < 14 GeV/c. Photons were detected with the highly segmented electromagnetic calorimeter ...

• Neutron-skin effect in direct-photon and charged-hadron production in Pb+Pb collisions at the LHC 

  Helenius, Ilkka; Paukkunen, Hannu; Eskola, Kari (Springer, 2017)

  A well-established observation in nuclear physics is that in neutron-rich spherical nuclei the distribution of neutrons extends farther than the distribution of protons. In this work, we scrutinize the influence of this ...
