22 Aug 2000 | | Journal: | Phys.Lett. B493 (2000) 127-134 | | Subject: | hep-ph | | Abstract: | Thanks to the focus point phenomenon, it is quite {it natural} for the minimal SUGRA model to have a large soft scalar mass m_0 > 1 TeV. A distinctive feature of this model is an inverted hierarchy, where the lighter stop has a significantly smaller mass than the other squarks and sleptons. Consequently, the gluino is predicted to decay dominantly via stop exchange into a channel containing 2b and 2W along with the LSP. We exploit this feature to construct a robust signature for this model at the LHC in leptonic channels with 3-4 b-tags and a large missing-E_T. | | Source: | arXiv, hep-ph/0008228 | | Services: | Forum | Review | PDF | Favorites | |
