Edge Detecting New Physics the Voronoi Way
Dipsikha Debnath, James S. Gainer, Doojin Kim +1
We point out that interesting features in high energy physics data can be determined from properties of Voronoi tessellations of the relevant phase space. For illustration, we focu…
The Hierarchy Solution to the LHC Inverse Problem
James S. Gainer, Konstantin T. Matchev, Myeonghun Park
Supersymmetric (SUSY) models, even those described by relatively few parameters, generically allow many possible SUSY particle (sparticle) mass hierarchies. As the sparticle mass h…
Precision studies of the Higgs boson decay channel H -> ZZ -> 4l with MEKD
Paul Avery, Dimitri Bourilkov, Mingshui Chen +10
The importance of the H -> ZZ -> 4l "golden" channel was shown by its major role in the discovery, by the ATLAS and CMS collaborations, of a Higgs-like boson with mass near 125 GeV…
Precise reconstruction of sparticle masses without ambiguities
Konstantin T. Matchev, Filip Moortgat, Luc Pape +1
We critically reexamine the standard applications of the method of kinematical endpoints for sparticle mass determination. We consider the typical decay chain in supersymmetry (SUS…
Using kinematic boundary lines for particle mass measurements and disambiguation in SUSY-like events with missing energy
Michael Burns, Konstantin T. Matchev, Myeonghun Park
We revisit the method of kinematical endpoints for particle mass determination, applied to the popular SUSY decay chain squark -> neutralino -> slepton -> LSP. We analyze the uniqu…
Using Subsystem MT2 for Complete Mass Determinations in Decay Chains with Missing Energy at Hadron Colliders
Michael Burns, Kyoungchul Kong, Konstantin T. Matchev +1
We propose to use the MT2 concept to measure the masses of all particles in SUSY-like events with two unobservable, identical particles. To this end we generalize the usual notion…
