Assuming a heavy SUSY spectrum, the most promising channels above the top quark mass are $H^pm o tb$ and $H^pm o au^pm
u_ au$ which provide coverage in the low and high $ aneta$ regions up to $sim 600$ GeV. The achievable precisions on the charged Higgs mass and $ aneta$ determination are also discussed. The $H^pm o W^pm h^0$ channel, though restricted to a small MSSM parameter space, shows a viable signal in NMSSM where the parameter space is less constrained. The observation of the channel $H^- o au^-_L
u_ au + c.c.$ may constitute a distinctive evidence for models with singlet neutrinos in large extra dimensions. | | Source: | arXiv, hep-ph/0203121 | | Services: | Forum | Review | PDF | Favorites | |
