Same - sign top quarks as signature of light stops 1
نویسنده
چکیده
We present a new method to search for a light scalar top (stop), decaying dominantly into cχ̃0 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.

Same-sign top quarks as signature of light stops at the CERN LHC
We present a new method to search for a light scalar top with t̃1 < ∼ mt, decaying dominantly into a c-jet and the lightest neutralino, 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. The resulting signature is 2 b-jets plus 2 same-sign leptons plus add...

متن کاملScalar Top Study: Detector Optimization
A vertex detector concept of the Linear Collider Flavour Identification (LCFI) collaboration, which studies pixel detectors for heavy quark flavour identification, has been implemented in simulations for c-quark tagging in scalar top studies. The production and decay of scalar top quarks (stops) is particularly interesting for the development of the vertex detector as only two c-quarks and miss...
متن کاملStops in R-parity Breaking Model for High-Q Events at HERA
We investigate an event excess in the reaction ep → eX with large x and high Q observed at HERA and show that the events could naturally be interpreted as a signature of the production of the scalar top quarks (stops) in a supersymmetric model with R-parity breaking interactions. The HERA events are characterized by the broad mass distribution and in fact it can be simulated by our specific sce...
متن کاملSame-Sign Dilepton Excesses and Vector-like Quarks
Multiple analyses from ATLAS and CMS collaborations, including searches for ttH production, supersymmetric particles and vector-like quarks, observed excesses in the same-sign dilepton channel containing b-jets and missing transverse energy in the LHC Run 1 data. In the context of little Higgs theories with T parity, we explain these excesses using vector-like T-odd quarks decaying into a top q...
