MT2 to the Rescue -- Searching for Sleptons in Compressed Spectra at the LHC
Zhenyu Han, Yandong Liu
We propose a novel method for probing sleptons in compressed spectra at hadron colliders. The process under study is slepton pair production in R-parity conserving supersymmetry, w…
J_{E_T}: A Global Jet Finding Algorithm
Yang Bai, Zhenyu Han, Ran Lu
We introduce a new jet-finding algorithm for a hadron collider based on maximizing a J_{E_T} function for all possible combinations of particles in an event. This function prefers…
Jet Radiation Radius
Zhenyu Han
Jet radiation patterns are indispensable for the purpose of discriminating partons' with different quantum numbers. However, they are also vulnerable to various contaminations from…
Hunting Quasi-Degenerate Higgsinos
Zhenyu Han, Graham D. Kribs, Adam Martin +1
We present a new strategy to uncover light, quasi-degenerate Higgsinos, a likely ingredient in a natural supersymmetric model. Our strategy focuses on Higgsinos with inter-state sp…
