Ultrarelativistic Nuclear Collisions as Seen Through Photons

Explore the intricacies of ultrarelativistic nuclear collisions through the lens of photon production in this theoretical physics colloquium presented by Prof. Jean-Francois Paquet from Vanderbilt University. Delve into the energy spectrum of photons in proton-proton and heavy-ion collisions, focusing on the significant differences observed in the single-GeV energy range. Examine the dominant role of electromagnetic radiation from deconfined nuclear matter plasma in heavy-ion collisions for lower-energy photon production. Review various photon production mechanisms, current theoretical calculations, and their agreement with experimental data. Investigate recent developments in the field and analyze the momentum anisotropy (v2, v3) of photons. Gain insights into this cutting-edge research as part of the theoretical physics colloquium series hosted by Prof. Igor Shovkovy at Arizona State University.
