AxionOrigins: towards a complete theory for the origin of the axion

25 Gennaio @ 10:00 - 26 Gennaio @ 15:00

This is the kickoff meeting of the PRIN 2022K4B58X project “AxionOrigins: towards a complete theory for the origin of the axion” (PI L. Di Luzio) which is a collaborative venture among INFN, University of Padua and Sapienza University of Rome.  The meeting will be held in the Salvini Auditorium (Bldg. 36, access from LNF secondary entrance in Via E. Fermi, 60 – see map).        (Talks by invitation only)You are welcome to download the conference poster here. Aim of the meeting:The aim of the meeting is to establish a collaborative network in association to the PRIN project AxionOrigins. The axion hypothesis, at the interface of particle physics, astrophysics and cosmology, is currently within the reach of experimental verification. However, almost half a century after the conception of the Peccei Quinn (PQ) mechanism, there is not yet a credible theory in which the PQ symmetry arises in a natural way (PQ origin problem). Moreover, the axion solution is notoriously fragile: possible ultraviolet contributions to the axion potential need to be extremely suppressed in order not to spoil the solution of the strong CP problem (PQ quality problem). AxionOrigins aims at identifying extensions of the Standard Model (SM) that incorporate a complete theory of the axion, providing a rationale both for the origin and quality of the PQ symmetry. These include model-building directions that integrate the axion framework with solutions of the SM flavour puzzle based on horizontal gauge symmetries, grand-unified theories and composite dynamics.   Important dates: January    12, 2024 –  Program announcement January    19, 2024 –  Deadline to register Organising Committee:Fernando Arias Aragón (INFN – LNF) Emanuele Bagnaschi (INFN – LNF)  Luca Di Luzio (INFN – Padua) Federico Mescia (INFN – LNF) Marco Nardecchia (Sapienza, Università di Roma & INFN – RM1) Enrico Nardi (INFN-LNF & HEPC-NICPB, Tallinn, Estonia) ZOOM January 25 2024Join Zoom Meeting Meeting ID: 916 3683 3007Passcode: 251117 ______________________________________________________ January 26 2024 Time: Jan 26, 2024 10:00 AM RomeJoin Zoom Meeting ID: 952 7257 2300Passcode: 176547
