R parity violating supersymmetric explanation for the CDF Wjj excess
Dilip Kumar Ghosh, Manas Maity, Sourov Roy
Recently CDF has reported a 4.1 sigma excess in the distribution of the dijet invariant mass between 120-160 GeV in Wjj event sample in 7.3 fb^{-1} of data, which has generated con…
Constraints on axino warm dark matter from X-ray observation at the Chandra telescope and SPI
Paramita Dey, Biswarup Mukhopadhyaya, Sourov Roy +1
A sufficiently long lived warm dark matter could be a source of X-rays observed by satellite based X-ray telescopes. We consider axinos and gravitinos with masses between 1 keV and…
Sneutrino-antisneutrino oscillation at the Tevatron
Dilip Kumar Ghosh, Tuomas Honkavaara, Katri Huitu +1
Sneutrino-antisneutrino oscillation can be a very useful probe to look for signatures of lepton number violation () at the Tevatron. Here, we discuss a scenario where the tot…
Constraints on composite Dirac neutrinos from observations of galaxy clusters
R. S. Hundi, Sourov Roy
Recently, to explain the origin of neutrino masses a model based on confining some hidden fermionic bound states into right-handed chiral neutrinos has been proposed. One of the co…
Resonant Leptogenesis with nonholomorphic R-Parity violation and LHC Phenomenology
Joydeep Chakrabortty, Sourov Roy
In R-parity violating supersymmetric models both leptogenesis and the correct neutrino masses are hard to achieve together. The presence of certain soft nonholomorphic R-parity vio…
