Title : ( Vacuum stability vs. positivity in real singlet scalar extension of the standard model )
Authors: Parsa Ghorbani ,
Full TextAbstract
We assume a generic real singlet scalar extension of the Standard Model living in the vacuum (v, w)at the electroweak scale with v=246 GeV and wbeing respectively the Higgs and the singlet scalar vacuum expectation values. By requiring absolutevacuum stability for the vacuum (v, w), the positivity condition and the perturbativity up to the Planck scale, we show that the viable space of parameters in the model is strongly constrained for various singlet scalar vacuum expectation values w=0.1, 1, 10, 100 TeV. Also, it turns out that the singlet scalar mass can be from a few GeV up to less than TeV.
