Copositive Criteria and Boundedness of the Scalar Potential

Understand

To understand physics beyond the Standard Model (SM) it is important to have the precise knowledge of Higgs boson and top quark masses as well as strong coupling.

• Recently discovered new boson which is likely to be the SM Higgs with mass 123-127 GeV has a submissive impact on the stability of the new physics beyond standard model (BSM).
• The beyond standard model scenarios that include many scalar fields posses scalar potential with many quartic couplings.
• Due to the complicated structures of such scalar potentials it is indeed difficult to adjudge the stability of the vacuum.
