چکیده

If the standard electroweak gauge model is extended to include two or more Higgs doublets, there may be a neutral Higgs boson h which is light (with a mass of say 10 GeV) but the hZZ coupling is suppressed so that it has so far escaped experimental detection. However, the effective hhZZ coupling is generally unsuppressed, hence the decay of Z into two light Higgs bosons plus a fermion-antifermion pair may have an observable branching fraction, especially if h decays invisibly as for example in the recently proposed doublet Majoron model.

Higgs and Z bosons decay into light gluinos.

We calculate the decay rate of scalar and pseudoscalar Higgs bosons into a pair of gluinos, within the Minimal Supersymmetric Standard Model. In the theoretically and experimentally allowed light gluino window, m ~ g 3{5 GeV, gluino pairs can completely dominate the decays of the light scalar Higgs boson and play a prominent role in the decay of the pseudoscalar Higgs boson. This would alter th...

Decay of Z into Three Pseudoscalar Bosons

We consider the decay of the Z boson into three pseudoscalar bosons in a general two-Higgs-doublet model. Assuming m A to be very small, and that of the two physical neutral scalar bosons h 1 and h 2 , A only couples to Z through h 1 , we find the Z → AAA branching fraction to be negligible for moderate values of tan β ≡ v 2 /v 1 , if there is no λ 5 (Φ † 1 Φ 2) 2 + h.c. term in the Higgs poten...

The Two-Photon Decay Mode of MSSM Higgs Bosons

At the Large Hadron Collider (LHC), the CP-even Higgs bosons (h and H) of the Minimal Supersymmetric Standard Model (MSSM) will be searched for mainly through their two-photon decay. We present a detailed analysis of the production and two-photon decay of the CP-even Higgs bosons of MSSM at the LHC by taking into account all the parameters of the model, especially the bilinear parameter μ and t...
