DESCRIPTION:Speakers: Osamu Seto (Hokkai-Gakuen University)\nWe consider a
  simple extension of the Higgs sector in a Higgs portal dark matter where 
 a real scalar is a candidate for dark matter in the present Universe. This
  Higgs sector extension allows that its dark matter annihilation suitably 
 explains the observed excess of the gamma-ray flux from the Galactic Cente
 r. We identify the parameter region of the model that can fit the gamma-ra
 y excess and satisfy phenomenological constraints\, such as the observed d
 ark matter relic density and the null results of direct dark matter search
  experiments.\n\nhttps://indico.icrr.u-tokyo.ac.jp/event/23/contributions/
