\sqrt{s}_min: a global inclusive variable for determining the mass scale of new physics in events with missing energy at hadron colliders
Partha Konar, Kyoungchul Kong, Konstantin T. Matchev
We propose a new global and fully inclusive variable \sqrt{s}_{min} for determining the mass scale of new particles in events with missing energy at hadron colliders. We define \sq…
Common gauge origin of discrete symmetries in observable sector and hidden sector
Taeil Hur, Hye-Sung Lee, Christoph Luhn
An extra Abelian gauge symmetry is motivated in many new physics models in both supersymmetric and nonsupersymmetric cases. Such a new gauge symmetry may interact with both the obs…
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…
Lightest U-parity Particle (LUP): a hidden sector dark matter candidate
Hye-Sung Lee
We introduce a new dark matter candidate, the lightest U-parity particle (LUP). We suggest it as a good dark matter candidate especially in the R-parity violating supersymmetric mo…
A General Method for Model-Independent Measurements of Particle Spins, Couplings and Mixing Angles in Cascade Decays with Missing Energy at Hadron Colliders
Michael Burns, Kyoungchul Kong, Konstantin T. Matchev +1
We outline a general strategy for measuring spins, couplings and mixing angles in the case of a heavy partner decay chain terminating in an invisible particle. We consider the comm…
Discrete Anomalies of Binary Groups
Christoph Luhn
We derive the discrete anomaly conditions for the binary tetrahedral group T' as well as the binary dihedral groups Q_2n. The ambiguities of embedding these finite groups into SU(2…
