SUMMARY:Rethinking the QCD axion - Luca di Luzio (DESY)
DTSTART:20201022T150000Z

CONTACT:Joseph Davighi
DESCRIPTION:Four decades after its prediction the axion remains the most c
 ompelling solution to the strong CP problem and a well motivated dark matt
 er candidate\, inspiring several ultrasensitive experiments based on axion
 -photon mixing. After reviewing the axion solution of the strong CP proble
 m and the experimental landscape of axion searches\, I will focus on some 
 recent developments in axion model building suggesting that the QCD axion 
 parameter space is much larger than what traditionally thought. The implic
 ations for astrophysical limits and current experiments will be discussed 
 as well.
