Consequences of f(R)-theories of gravity on gravitational leptogenesis
G. Lambiase, S. Mohanty, L. Pizza
f(R)-theories of gravity are reviewed in the framework of the matter-antimatter asymmetry in the Universe. The asymmetry is generated by the gravitational coupling of heavy (Majora…
Thermodynamic Properties of Strongly Interacting Matter in a Finite Volume using the Polyakov-Nambu-Jona-Lasinio model
Abhijit Bhattacharyya, Paramita Deb, Sanjay K. Ghosh +2
We present the thermodynamic properties of strongly interacting matter in finite volume in the framework of Polyakov loop enhanced NambuJona-lasinio model within mean field appr…
Vacuum Stability Constraints on the Minimal Singlet TeV Seesaw Model
Subrata Khan, Srubabati Goswami, Sourov Roy
We consider the minimal seesaw model in which two gauge singlet right handed neutrinos with opposite lepton numbers are added to the Standard Model. In this model, the smallness of…
Probing chromomagnetic and chromoelectric couplings of the top quark using its polarization in pair production at hadron colliders
Sudhansu S. Biswal, Saurabh D. Rindani, Pankaj Sharma
The Tevatron, where the top quark was discovered, and the currently functional Large Hadron Collider (LHC), with copiously produced top pairs, enable a detailed study of top-quark…
Two Zero Mass Matrices and Sterile Neutrinos
Monojit Ghosh, Srubabati Goswami, Shivani Gupta
Recent experimental data is indicative of the existence of sterile neutrinos. The minimal scheme that can account for the data and is consistent with cosmological observations is t…
Determining neutrino mass hierarchy from electron disappearance at a Low energy neutrino factory
Rupak Dutta, Nita Sinha, Sushant K. Raut
Recent measurements of large theta_{13} by Daya Bay and RENO reactor experiments have opened up the possibility of determining the neutrino mass hierarchy, i.e. the sign of the mas…
