1. Measuring the mass, width, and couplings of semi-invisible 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 semi-invisibly decaying resonances. [...]

2. Probing the Triple Higgs Self-Interaction 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 +bb¯+ET final state. [...]

3. How to prove that a ET 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. [...]

4. Identifying phase-space 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. [...]

5. 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 model-independent as possible. [...]

6. On-shell 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 on-shell 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. [...]
