Supersymmetric Model with Higgs Triplet
Abstract
We present a study of the Higgs sector within an extension of the Minimal Supersymmetric Standard Model that includes one Complex Higgs Triplet (MSSM+1CHT). The model spectrum includes three singly charged Higgs bosons as well as three CP-even (or scalar) and two CP-odd (or pseudoscalar) neutral Higgs bosons. We present an approximated calculation of the one-loop radiative corrections to the neutral CP-even Higgs masses (m{sub Hi}{sup 0}) and the couplings H{sub i}{sup 0}Z{sup 0}Z{sup 0}(i = 1,2,3), which determine the magnitude of the Higgs-strahlung processes e{sup +}e{sup -}{yields}Z{sup 0}H{sub i}{sup 0}. Limits from LEP2 are then considered, in order to obtain bounds on the neutral Higgs sector. Further, we also include the experimental limits from LEP2 on e{sup +}e{sup -}{yields}H{sup +}H{sup -} and those on BR(t{yields}bH{sup +}) from Tevatron, to derive bounds on the mass of the two lightest charged Higgs bosons (H{sub 1}{sup {+-}} and H{sub 2}{sup {+-}}). Concerning the latter, we find some cases, where m{sub H1}{sup {+-}} congruent with 90 GeV, that are not excluded by any experimental bound, even for large values of tan{beta}, so that they should be looked for at the Large Hadron Collider (LHC)
