Using sorted invariant mass variables to evade combinatorial ambiguities in cascade decays
Doojin Kim, Konstantin T. Matchev, Myeonghun Park
The classic method for mass determination in a SUSY-like cascade decay chain relies on measurements of the kinematic endpoints in the invariant mass distributions of suitable colle…
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…
Discovering New Physics with Voronoi Tessellations
Dipsikha Debnath, James S. Gainer, Doojin Kim +1
High energy experimental data can be viewed as a sampling of the relevant phase space. We point out that one can apply Voronoi tessellations in order to understand the underlying p…
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…
