A search for pair-produced charged Higgs bosons in Z0 decays

Charm Decays as Evidence for Charged Higgs Bosons

It is suggested that the recent anomalous data on Cabibbo-suppressed charm decays can be interpreted as a manifestation of a charged Higgs boson. If this were true, it would be the first experimental detection of a Higgs contribution. At the least, it demonstrates that large, interesting Higgs (i.e., scalar) contributions are consistent with present experimental constraints. Predictions are giv...

τ − ν τ Decays and Implications for Charged Higgs Bosons

Direct search for charged higgs bosons in decays of top quarks.

We present a search for charged Higgs bosons in decays of pair-produced top quarks in pp collisions at sqrt[s] = 1.8 TeV recorded by the D0 detector at the Fermilab Tevatron collider. With no evidence for signal, we exclude most regions of the ( M(H+/-),tan(beta)) parameter space where the decay t--> H(+)b has a branching fraction >0.36 and B(H+/--->tau(nu)(tau)) is large.

Search for doubly charged Higgs bosons with lepton-flavor-violating decays involving tau leptons.

We search for pair production of doubly charged Higgs particles (H+/- +/-) followed by decays into electron-tau (etau) and muon-tau (mutau) pairs using data (350 pb(-1) collected from [over]pp collisions at sqrt[s]=1.96 TeV by the CDF II experiment. We search separately for cases where three or four final-state leptons are detected, and combine results for exclusive decays to left-handed etau (...

Tools for Charged Higgs Bosons

In order to identify the Higgs sector realized in nature, the predictions for Higgs boson masses, production cross sections and decay widths have to be compared with experimental results. We give a brief overview about computer codes for the evaluation of the properties of charged Higgs bosons, mostly focusing on the case of the Minimal Supersymmetric Standard Model (MSSM). We briefly review th...
