Boosting Invisible Higgs Searches by Tagging a Gluon Jet for Gluon Fusion Process

Won Sang Cho, Hyung Do Kim, Dongsub Lee

We propose a novel method in that quark-gluon tagging of the jets emitted as initial state radiation (ISR) can boost searches of invisible Higgs from gluon fusion processes against…

The 750 GeV Diphoton Excess May Not Imply a 750 GeV Resonance

Won Sang Cho, Doojin Kim, Kyoungchul Kong +4

We discuss non-standard interpretations of the 750 GeV diphoton excess recently reported by the ATLAS and CMS Collaborations which do not involve a new, relatively broad, resonance…

OPTIMASS: A Package for the Minimization of Kinematic Mass Functions with Constraints

Won Sang Cho, James S. Gainer, Doojin Kim +5

Reconstructed mass variables, such as , , , and , play an essential role in searches for new physics at hadron colliders. The calculation of these…

Improving the sensitivity of stop searches with on-shell constrained invariant mass variables

Won Sang Cho, James S. Gainer, Doojin Kim +4

The search for light stops is of paramount importance, both in general as a promising path to the discovery of beyond the standard model physics and more specifically as a way of e…

On-shell constrained variables with applications to mass measurements and topology disambiguation

Won Sang Cho, James S. Gainer, Doojin Kim +4

We consider a class of on-shell constrained mass variables that are 3+1 dimensional generalizations of the Cambridge variable and that automatically incorporate various as…

Probing resonance decays to two visible and multiple invisible particles

Won Sang Cho, Doojin Kim, Konstantin T. Matchev +1

We consider the decay of a generic resonance to two visible particles and any number of invisible particles. We show that the shape of the invariant mass distribution of the two vi…
