Resonant Higgs pair production as a probe of stop at the LHC

Searching for top squark (stop) is a crucial task of the LHC. When the flavor conserving two body decays of the stop are kinematically forbidden, the stops produced near the threshold will live long enough to form bound states which subsequently decay through annihilation into the Standard Model (SM) final states. In the region of stop mixing angle \( {\theta}_{\tilde{t}}\to 0 \) ...

Leptonic mono-top from single stop production at the LHC

Top squark (stop) can be produced via QCD interaction but also the electroweak interaction at the LHC. In this paper, we investigate the observability of the associated production of stop and chargino, \( pp\to {\tilde{t}}_1{\tilde{\chi}}_{\overline{1}} \), in compressed electroweakino scenarios at 14 TeV LHC. Due to small mass splitting between the lightest neutralino (\( ...
