Precise reconstruction of sparticle masses without ambiguities
Konstantin T. Matchev, Filip Moortgat, Luc Pape +1
We critically reexamine the standard applications of the method of kinematical endpoints for sparticle mass determination. We consider the typical decay chain in supersymmetry (SUS…
Using kinematic boundary lines for particle mass measurements and disambiguation in SUSY-like events with missing energy
Michael Burns, Konstantin T. Matchev, Myeonghun Park
We revisit the method of kinematical endpoints for particle mass determination, applied to the popular SUSY decay chain squark -> neutralino -> slepton -> LSP. We analyze the uniqu…
Using Subsystem MT2 for Complete Mass Determinations in Decay Chains with Missing Energy at Hadron Colliders
Michael Burns, Kyoungchul Kong, Konstantin T. Matchev +1
We propose to use the MT2 concept to measure the masses of all particles in SUSY-like events with two unobservable, identical particles. To this end we generalize the usual notion…
Kaluza-Klein Dark Matter: Direct Detection vis-a-vis LHC
Sebastian Arrenberg, Laura Baudis, Kyoungchul Kong +2
We explore the phenomenology of Kaluza-Klein (KK) dark matter in very general models with universal extra dimensions (UEDs), emphasizing the complementarity between high-energy col…
Discrete gauge symmetries and proton stability in the U(1)'-extended MSSM
Hye-Sung Lee, Christoph Luhn, Konstantin T. Matchev
The Minimal Supersymmetric Standard Model (MSSM) with conserved R-parity suffers from several fine-tuning problems, e.g. the mu-problem and the problem of proton decay through high…
Connecting LHC, ILC, and Quintessence
Daniel J. H. Chung, Lisa L. Everett, Kyoungchul Kong +1
If the cold dark matter consists of weakly interacting massive particles (WIMPs), anticipated measurements of the WIMP properties at the Large Hadron Collider (LHC) and the Interna…
