DESCRIPTION:Speakers: Tevong You (University of Cambridge)\nCosmological r
 elaxation of the electroweak scale employing the minimal QCD relaxion mech
 anism is still viable\, provided inflation occurs at finite temperature. T
 he $\\Theta$-angle problem of the original model is overcome by suppressin
 g the barrier size during relaxation. After relaxation\, the suppression i
 s removed and the barrier growth gives rise to the required value of $\\Th
 eta \\sim \\mathcal{O}(10^{-9})$. In contrast to other solutions of QCD re
 laxion models\, no axion-inflaton coupling is required.  In this case the 
 resolution comes about through a modification of the inflation sector\, in
 dependently of the relaxion implementation.\n\nhttps://indico.ific.uv.es/e
