SUMMARY:Florian Loebbert\, Humboldt University - Quantum Gravity and the Hi
 ggs Vacuum
DESCRIPTION:Understanding the Higgs effective potential is important for ma
 king statements on the stability of the standard model vacuum. In order to
  compute this potential\, all physical interactions should be taken into a
 ccount. Here we demonstrate how to include gravitational effects into the 
 computation of the standard model effective potential. While the pure quan
 tum gravitational contributions are small as expected\, non-renormalizabil
 ity of Einstein gravity induces higher dimensional operators with novel co
 uplings to the standard model Lagrangian. These additional operators imply
  that the true minimum of the effective potential is generically pushed be
 low the Planck scale. Finally\, we discuss the impact of the gravity-induc
 ed contributions on electroweak vacuum stability.
