Summary

Calculating the effective potentialVeff(φ1,φ2), in terms of two Higgs doublets in the one-loop approximation forSU2U1, charged and neutral Higgs-boson masses can be derived explicitly. In the presence of an invisible axion with an extra Higgs singletF, the influence of the pseudoscalar on the Higgs spectrum can be obtained withVeff(φ1,φ2;F) respectively simply via the tadpole method usingVeff(〈φ1,201, 2; 〈F00) only.

Riassunto

Calcolando il Potenziale efficaceVeff(φ1,φ2)in termini di due doppietti di Higgs nel-Papprossimazione ad un loop per SU2⊗U1 si possono derivare esplicitamente le masse dei bosoni di Higgs carichi e neutri. In presenza di un assione invisibile con un singoletto extra di HiggsF, si può ottenere l’influenza del pseudoscalare sullo spettro di Higgs conVeff(φ1,φ2;F) rispettivamente semplicemente con il metodo del tadpole usando va) soltanto.
