Scrutinizing vacuum stability in IDM with Type-III inverse seesaw

A bstract We consider the extension of Standard Model (SM) with an inert Higgs doublet that also contains two or three sets SU(2) L triplet fermions hypercharge zero and analyze stability electroweak vacuum for scenarios. The model represents a Type-III inverse seesaw mechanism neutrino mass generation Dark matter candidate. An effective potential approach calculation two-loop beta function have been carried out in deciding fate vacuum. Weak gauge coupling g 2 shows different behaviour as compared to Model. modified running , along quartic Yukawa couplings become crucial determining interplay between generations such reveals extensions is favoured if we aspire Planck scale stability. Bounds on couplings, number fermion are drawn fermions. phenomenologies at LHC other experiments commented upon.
