Description

Speaker: Maria Paola Lombardo, INFN Sezione di Firenze  Title:Topology of strong interactions,between the QCD and the EW transition. 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 ofthe hot medium  and possibly its experimental signatures; foreven higher temperatures, topology determines the density ofthe QCD axions, which are candidate  dark matter particles. The talk will focus on results for the topological charge, its susceptibility and its correlatorin the QCD plasma, and on their  implications on  the aspects outlined above.   Saletta Riunioni, ore 16
