Same-sign top quarks as signature of light stops
arXiv:hep-ph/0609293 · doi:10.1063/1.2735166
Abstract
We present a new method to search for a light scalar top (stop), decaying dominantly into $c\tildeÏ^0_1$, at the LHC. The principal idea is to exploit the Majorana nature of the gluino, leading to same-sign top quarks in events of gluino pair production followed by gluino decays into top and stop. We demonstrate the reach of our method in terms of the gluino mass and the stop-neutralino mass difference.
