Bisection-based asymmetric MT2 computation: a higher precision calculator than existing symmetric methods
Christopher G. Lester, Benjamin Nachman
An MT2 calculation algorithm is described. It is shown to achieve better precision than the fastest and most popular existing bisection-based methods. Most importantly, it is also…
Sneaky light stop
Till Eifert, Benjamin Nachman
A light supersymmetric top quark partner (stop) with a mass nearly degenerate with that of the Standard Model (SM) top quark can evade direct searches. The precise measurement of S…
A Meta-analysis of the 8 TeV ATLAS and CMS SUSY Searches
Benjamin Nachman, Tom Rudelius
Between the ATLAS and CMS collaborations at the LHC, hundreds of individual event selections have been measured in the data to look for evidence of supersymmetry at a center of mas…
Jet Charge with the ATLAS Detector using TeV Collision Data
Benjamin Nachman
The momentum-weighted sum of the charges of tracks associated to a jet provides an experimental handle on the electric charge of fundamental strongly-interacting particles. An over…
Spatial Mass
Benjamin Nachman, Ariel Schwartzman
In analogy to the transverse mass constructed from two objects, we define the spatial mass constructed from the input objects 3-vector momenta. This observable is insensitive to je…
Jets from Jets: Re-clustering as a tool for large radius jet reconstruction and grooming at the LHC
Benjamin Nachman, Pascal Nef, Ariel Schwartzman +2
Jets with a large radius and grooming algorithms are widely used to fully capture the decay products of boosted heavy particles at the Large Hadron Collider (LHC). Unl…
