Graviton production with 2 jets at the LHC in large extra dimensions
Kaoru Hagiwara, Partha Konar, Qiang Li +2
We study Kaluza-Klein (KK) graviton production in the large extra dimensions model via 2 jets plus missing transverse momentum signatures at the LHC. We make predictions for both t…
Next-to-leading order QCD corrections to slepton pair production via vector-boson fusion
Partha Konar, Dieter Zeppenfeld
Slepton pairs can be produced in vector-boson fusion processes at hadron colliders. The next-to-leading order QCD corrections to the electroweak production cross section for p p ->…
Looking for a heavy wino LSP in collider and dark matter experiments
Utpal Chattopadhyay, Debottam Das, Partha Konar +1
We investigate the phenomenology of a wino LSP as obtained in AMSB and some string models. The WMAP constraint on the DM relic density implies a wino LSP mass of 2.0-2.3 TeV. We fi…
Looking for a Heavy Higgsino LSP in Collider and Dark Matter Experiments
Utpal Chattopadhyay, Debajyoti Choudhury, Manuel Drees +2
A large part of the mSUGRA parameter space satisfying the WMAP constraint on the dark matter relic density corresponds to a higgsino LSP of mass TeV. We find a promising…
Gauge boson fusion as a probe of inverted hierarchies in supersymmetry
Partha Konar, Biswarup Mukhopadhyaya
Supersymmetric scenarios with inverted mass hierarchy can be hard to observe at a hadron collider, particularly for the non-strongly interacting sector. We show how the production…
Bhabha Scattering with Radiated Gravitons at Linear Colliders
Sukanta Dutta, Partha Konar, Biswarup Mukhopadhyaya +1
We study the process e+- e- -> e+- e- +- missing energy at a high-energy e+- e- collider, where the missing energy arises from the radiation of Kaluza-Klein gravitons in a model wi…
