The Machine Learning Landscape of Top Taggers
G. Kasieczka, T. Plehn, A. Butter +24
Based on the established task of identifying boosted, hadronically decaying top quarks, we compare a wide range of modern machine learning approaches. Unlike most established metho…
Enhancing the discovery prospects for SUSY-like decays with a forgotten kinematic variable
Dipsikha Debnath, James S. Gainer, Can Kilic +3
The lack of a new physics signal thus far at the Large Hadron Collider motivates us to consider how to look for challenging final states, with large Standard Model backgrounds and…
Measuring the mass, width, and couplings of semi-invisible resonances with the Matrix Element Method
Amalia Betancur, Dipsikha Debnath, James S. Gainer +2
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 r…
Resolving Combinatorial Ambiguities in Dilepton Event Topologies with Constrained Variables
Dipsikha Debnath, Doojin Kim, Jeong Han Kim +2
We advocate the use of on-shell constrained variables in order to mitigate the combinatorial problem in SUSY-like events with two invisible particles at the LHC. We show that…
LHC Collider Phenomenology of Minimal Universal Extra Dimensions
Jyotiranjan Beuria, AseshKrishna Datta, Dipsikha Debnath +1
We discuss the collider phenomenology of the model of Minimal Universal Extra Dimensions (MUED) at the Large hadron Collider (LHC). We derive analytical results for all relevant st…
Detecting kinematic boundary surfaces in phase space: particle mass measurements in SUSY-like events
Dipsikha Debnath, James S. Gainer, Can Kilic +3
We critically examine the classic endpoint method for particle mass determination, focusing on difficult corners of parameter space, where some of the measurements are not independ…
Identifying Phase Space Boundaries with Voronoi Tessellations
Dipsikha Debnath, James S. Gainer, Can Kilic +3
Determining the masses of new physics particles appearing in decay chains is an important and longstanding problem in high energy phenomenology. Recently it has been shown that the…
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…
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…
Model-Independent Searches Using Matrix Element Ranking
Dipsikha Debnath, James S. Gainer, Konstantin T. Matchev
Thus far the LHC experiments have yet to discover beyond-the-standard-model physics. This motivates efforts to search for new physics in model independent ways. In this spirit, we…
Discoveries far from the Lamppost with Matrix Elements and Ranking
Dipsikha Debnath, James S. Gainer, Konstantin T. Matchev
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. We describe procedures for adapt…
