DESCRIPTION:Tobioka Kohsaku\nThe cosmological relaxation of the electrowea
 k scale has been proposed as a mechanism to address the hierarchy problem 
 of the Standard Model. A field\, the relaxion\, rolls down its potential a
 nd scans the squared mass parameter of the Higgs. In the original proposal
 \, the rolling takes place in the background of inflation.\nIn my talk\, I
  discuss a scenario that the relaxion is an inflaton and in addition it co
 uples to to Abelian gauge bosons. This introduces a new dissipation mechan
 ism and allows for reheating at the end of inflation. The reheating mechan
 ism proceeds via the vacuum production of electron-positron pairs\, due to
  the presence of strong electric and magnetic fields. Also I discuss the c
 osmological dynamics of the model and the phenomenological constraints fro
 m CMB and other experiments.
