Dark Matter Particle Spectroscopy at the LHC: Generalizing MT2 to Asymmetric Event Topologies
Partha Konar, Kyoungchul Kong, Konstantin T. Matchev +1
We consider SUSY-like missing energy events at hadron colliders and critically examine the common assumption that the missing energy is the result of two identical missing particle…
Superpartner mass measurements with 1D decomposed MT2
Partha Konar, Kyoungchul Kong, Konstantin T. Matchev +1
We propose a new model-independent technique for mass measurements in missing energy events at hadron colliders. We illustrate our method with the most challenging case of a short,…
A general method for determining the masses of semi-invisibly decaying particles at hadron colliders
Konstantin T. Matchev, Myeonghun Park
We present a general solution to the long standing problem of determining the masses of pair-produced, semi-invisibly decaying particles at hadron colliders. We define two new tran…
Precision sparticle spectroscopy in the inclusive same-sign dilepton channel at LHC
Konstantin T. Matchev, Filip Moortgat, Luc Pape +1
The inclusive same-sign dilepton channel is already recognized as a promising discovery signature for supersymmetry in the early days of the LHC. We point out that it can also be u…
Shedding Light on the Dark Sector with Direct WIMP Production
Partha Konar, Kyoungchul Kong, Konstantin T. Matchev +1
A Weakly Interacting Massive Particle (WIMP) provides an attractive dark matter candidate, and should be within reach of the next generation of high-energy colliders. We consider t…
