Topology of strong interactions, between the QCD and the EW transition
Seminars
Seminar “Theory of Hadronic Matter under Extreme Conditions”
Date and Time: Wednesday, 29 May 2019, at 4:00 PM
Venue: Blokhintsev Hall (4th floor), Bogoliubov Laboratory of Theoretical Physics
Seminar topic: “Topology of strong interactions, between the QCD and the EW transition”
Speaker: Maria Paola Lombardo (INFN, Italy)
Abstract:
Strong interactions’ topology is a rich theoretical subject with phenomenological implications: at low temperature topology holds the key to a complete understanding of the hadron spectrum; around the QCD transition the interplay of topology, axial and chiral symmetries affects the nature of the hot medium and possibly its experimental signatures; for even higher temperatures, topology determines the density of the QCD axions, which are candidate dark matter particles. The talk will focus on results for the topological charge, its susceptibility and its correlator in the QCD plasma, and on their implications on the aspects outlined above.
