Leptogenesis by curvature coupling of heavy neutrinos
Gaetano Lambiase, Subhendra Mohanty
We introduce a CP violating coupling between the Ricci curvature and the heavy right handed neutrinos. This splits the Majorana masses of the left and the right handed heavy neutri…
Probing the Role of Magnetic-Field Variations in NOAA AR 8038 in Producing Solar Flare and CME on 12 May 1997
Rajmal Jain, Arun K. Awasthi, Babita Chandel +3
We carried out a multi-wavelength study of a CME and a medium-size 1B/C1.3 flare occurring on 12 May 1997. We present the investigation of magnetic-field variations in the NOAA Act…
Rapid optical variability in blazar S5 0716+71 during 2010 March
Sunil Chandra, K. S. Baliyan, S. Ganesh +1
We report rapid optical variability for the blazar S5 0716+71 during 2010 March 08-10 & 19-20 in the CCD observations made from Mt.Abu Infrared Observatory. The light curves are co…
Lorentz invariant dark-spinor and inflation
Abhishek Basak, Jitesh R. Bhatt
We investigate the possibility of the inflation driven by a Lorentz invariant non-standard spinor field. As these spinors are having dominant interaction via gravitational field on…
Energy-Dependent Timing of Thermal Emission in Solar Flares
Rajmal Jain, Arun Kumar Awasthi, Arvind Singh Rajpurohit +1
We report solar flare plasma to be multi-thermal in nature based on the theoretical model and study of the energy-dependent timing of thermal emission in ten M-class flares. We emp…
Fermion Masses in SO(10) Models
Anjan S. Joshipura, Ketan M. Patel
We examine many SO(10) models for their viability or otherwise in explaining all the fermion masses and mixing angles. This study is carried out for both supersymmetric and non-sup…
