TL;DR
This paper investigates single top production at the LHC within a non-minimal supersymmetric model featuring a heavy Dirac gluino, highlighting unique flavor-changing processes and distinctive top production signatures.
Contribution
It introduces a SUSY-QCD model with a heavy Dirac gluino and analyzes its impact on single top production via FCNCs at the LHC, emphasizing the process ug->tg.
Findings
The process ug->tg dominates single top production via FCNCs.
Top quarks are produced very forward in this scenario.
The top and anti-top production asymmetry is significant.
Abstract
We study single top production at the LHC in a SUSY-QCD model with a heavy Dirac gluino. The presence of a heavy Dirac gluino allows for notable top-up flavour changing neutral currents. In this scenario, we find that the process ug->tg gives the largest contribution to single top production via FCNCs at the LHC. The key features of this signal are that the top quark is produced very forward and that it is asymmetric to its anti-top counterpart, as the latter lacks a valence quark.
