Measuring the mass, width, and couplings of semiinvisible resonances with the matrix element method
/ Betancur, Amalia ; Debnath, Dipsikha ; Gainer, James S. ; Matchev, Konstantin T. ; et al
We demonstrate the use of the matrix element method (MEM) for the measurement of masses, widths, and couplings in the case of single or pair production of semiinvisibly decaying resonances. [...]

Probing the Triple Higgs SelfInteraction at the Large Hadron Collider
/ Kim, Jeong Han ; Kong, Kyoungchul ; Matchev, Konstantin T. ; Park, Myeonghun
We propose a novel kinematic method to expedite the discovery of the double Higgs ($hh$) production in the ${\ell}^{+}{\ell}^{}b\overline{b}+{E}_{T}$ final state. [...]

How to prove that a ${E}_{T}$ excess at the LHC is not due to dark matter
/ Kim, Doojin ; Matchev, Konstantin T.
If the LHC is able to produce dark matter particles, they would appear at the end of cascade decay chains, manifesting themselves as missing transverse energy. [...]

Identifying phasespace boundaries with Voronoi tessellations
/ Debnath, Dipsikha ; Gainer, James S. ; Kilic, Can ; Kim, Doojin ; et al
Determining the masses of new physics particles appearing in decay chains is an important and longstanding problem in high energy phenomenology. [...]

Discoveries far from the lamppost with matrix elements and ranking
/ Debnath, Dipsikha ; Gainer, James S. ; Matchev, Konstantin T.
The prevalence of null results in searches for new physics at the LHC motivates the effort to make these searches as modelindependent as possible. [...]

Onshell constrained M 2 variables with applications to mass measurements and topology disambiguation
/ Won Sang Cho ; James S. Gainer ; Doojin Kim ; Konstantin T. Matchev ; et al
We consider a class of onshell constrained mass variables that are 3+1 dimensional generalizations of the Cambridge M T 2 variable and that automatically incorporate various assumptions about the underlying event topology. [...]
