Supersymmetric Model with Higgs Triplet

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 Hig...

Description
Summary: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') and the couplings H'Z0Z0(i = 1,2,3), which determine the magnitude of the Higgs-strahlung processes e+e-'Z0H'. 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+e-'H+H- and those on BR(t'bH+) from Tevatron, to derive bounds on the mass of the two lightest charged Higgs bosons (H' and H'). Concerning the latter, we find some cases, where m'~90 GeV, that are not excluded by any experimental bound, even for large values of tanb, so that they should be looked for at the Large Hadron Collider (LHC).
