Right-handed Neutrino Dark Matter in a U(1) Extension of the Standard Model
Peter Cox, Chengcheng Han, Tsutomu T. Yanagida
We consider minimal extensions of the Standard Model in which one of the right-handed neutrinos is charged under the new gauge symmetry and plays the role of dark matter. In…
Surviving scenario of stop decays for ATLAS search
Chengcheng Han, Mihoko M. Nojiri, Michihisa Takeuchi +1
Recently ATLAS reported a excess in the stop search with channel. We try to interpret the signal by a light stop pair production in the MSSM. We find:…
Identifying a new particle with jet substructures
Chengcheng Han, Doojin Kim, Minho Kim +3
We investigate a potential of measuring properties of a heavy resonance X, exploiting jet substructure techniques. Motivated by heavy higgs boson searches, we focus on the decays o…
SUSY effects in Higgs productions at high energy colliders
Junjie Cao, Chengcheng Han, Jie Ren +3
Considering the constraints from collider experiments and dark matter detections, we investigate the SUSY effects in the Higgs productions at an collider w…
A new approach for detecting compressed bino/wino at the LHC
Chengcheng Han, Lei Wu, Jin Min Yang +2
In some supersymmetric models like split supersymmetry or models with non-universal gaugino mass, bino (LSP) and winos (NLSP) may have rather small mass splitting in order to provi…
Probing light bino and higgsinos at the LHC
Chengcheng Han
Motivated by the naturalness, we study a simplified MSSM scenario where only the bino-like LSP and higgsino-like NLSP are light. We first scan the parameter space of this scenario,…
