Influence of mixing angles on testing for light Higgs particles

  • Published:
Il Nuovo Cimento A (1965-1970)

Summary

Calculating the relevant mixing angles in a model in which the Higgs mass spectrum was derived perturbatively via the effective potential method in the one-loop approximation forSU 2U 1 in terms of two Higgs doubletsϕ 1,2 and an extra Higgs singletF, the production and decay rates for these light Higgs particles can be enhanced and, in the case of quarkonium decays,e.g., overcome dominant back-ground effects.

Riassunto

Calcolando gli angoli rilevanti di mescolamento in un modello in cui lo spettro di massa di Higgs è stato derivato perturbativamente con il metodo del potenziale efficace nell’approssimazione a un loop perSU 2U 1 in termini dei due doppietti di Higgsϕ 1,2 e un singoletto extra di HiggsF, si può incrementare la produzione e i tassi di decadimento per queste particelle di Higgs leggere e, nel caso di decadimento del quarkonio, per esempio, superare gli effetti dominanti di background.
