Bounded-From-Below Constraints for General Higgs PotentialsI. P. Ivanov1, •M. Köpke2, and M. M. Mühlleitner21Instituto Superior Tecnico, Lisbon, Portugal — 2KIT, Institute for Theoretical Physics, Karlsruhe, Germany

In theories with interacting scalar fields, the scalar Higgs potential must be bounded from below in order for a stable vacuum to exist. For general Higgs potentials these constraints for boundedness-from-below are difficult to derive. In the past, they were usually studied on a model by model basis and involved lengthy proofs of inequalities. In this talk, I present a method that can be applied to general Higgs potentials and carried out by a computer, resulting in analytic expressions that can be used to check for the validity of a parameter point of the model.
