Perturbative calculations of higgs boson masses

  • Published:
Il Nuovo Cimento A (1971-1996)

Summary

Calculating the effective potentialV eff(φ 1,φ 2), in terms of two Higgs doublets in the one-loop approximation forSU 2⊗U 1, 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 withV eff(φ 1,φ 2;F) respectively simply via the tadpole method usingV eff(〈φ 1,2〉0=υ1, 2; 〈F〉0=υ0) only.

Riassunto

Calcolando il Potenziale efficaceV eff(φ 1,φ 2)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 conV eff(φ 1,φ 2;F) rispettivamente semplicemente con il metodo del tadpole usando va) soltanto.
