Corrections to Tri-bimaximal Neutrino Mixing: Renormalization and Planck Scale Effects
Amol Dighe, Srubabati Goswami, Werner Rodejohann
We study corrections to tri-bimaximal (TBM) neutrino mixing from renormalization group (RG) running and from Planck scale effects. We show that while the RG effects are negligible…
Constraints on flavor-dependent long range forces from solar neutrinos and KamLAND
Abhijit Bandyopadhyay, Amol Dighe, Anjan S. Joshipura
Flavor-dependent long range (LR) leptonic forces, like those mediated by the or gauge bosons, constitute a minimal extension of the standard model that preserv…
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…
Thermodynamics of the PNJL model with nonzero baryon and isospin chemical potentials
Swagato Mukherjee, Munshi G. Mustafa, Rajarshi Ray
We have extended the Polyakov-Nambu-Jona-Lasinio (PNJL) model for two degenerate flavours to include the isospin chemical potential (). All the diagonal and mixed derivatives…
Signature of heavy Charged Higgs Boson at LHC in the 1 and 3 prong Hadronic Tau Decay channels
Monoranjan Guchait, Ritva Kinnunen, D. P. Roy
We have done a fast simulation analysis of the charged Higgs signal at LHC in the 1 and 3 prong hadronic -jet channels along with the background. The polarization…
Solar Model Parameters and Direct Measurements of Solar Neutrino Fluxes
Abhijit Bandyopadhyay, Sandhya Choubey, Srubabati Goswami +1
We explore a novel possibility of determining the solar model parameters, which serve as input in the calculations of the solar neutrino fluxes, by exploiting the data from direct…
