Abstract
地 点 |
Given its importance in stabilizing the Higgs mass, probing the
superpartner of top quark is a high-priority study at the Large
Hadron Collider (LHC). In my talk, I will describe the search
strategies we developed for the top squark (called stop) at the
LHC. When the top squarks are produced from the cascade decay
of gluino and squarks, our analysis is performed in the
stop-neutralino coannihilation region where stop decays into
a charm quark and the stable lightest supersymmetric particle
(called neutralino1). When the top squarks are produced from
the direct production, I will show you our analysis in fully
hadronic final state (0-lepton) and 2-lepton final state
(with neutralino1 as a Bino-Higgsino mixture). I will also show
you our latest result in the very challenging compressed scenario
where the mass difference between stop and neutralino1 is
approximately equal to the mass the top quark. |
