Same-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...
متن کاملSame - sign top quarks as signature of light stops 1
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.
متن کاملDiscovering the top partners at the LHC using same-sign dilepton final states
A natural, non-supersymmetric solution to the hierarchy problem generically requires fermionic partners of the top quark with masses not much heavier than 500GeV. We study the pair production and detection at the LHC of the top partners with electric charge Qe = 5/3 (T5/3) and Qe = −1/3 (B), that are predicted in models where the Higgs is a pseudo-Goldstone boson. The exotic T5/3 fermion, in pa...
متن کاملSearch for top-quark partners with charge 5/3 in the same-sign dilepton final state.
A search for the production of heavy partners of the top quark with charge 5/3 is performed in events with a pair of same-sign leptons. The data sample corresponds to an integrated luminosity of 19.5 fb(-1) and was collected at sqrt[s] = 8 TeV by the CMS experiment. No significant excess is observed in the data above the expected background, and the existence of top-quark partners with masses b...
متن کاملSame-sign top quarks as signature of light stops at the 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...
