Maximal mixing as a `sum' of small mixings
Joydeep Chakrabortty, Anjan S. Joshipura, Poonam Mehta +1
In models with two sources of neutrino masses, we look at the possibility of generating maximal/large mixing angles in the total mass matrix, where both the sources have only small…
GUTs with dim-5 interactions: Gauge Unification and Intermediate Scales
Joydeep Chakrabortty, Amitava Raychaudhuri
Dimension-5 corrections to the gauge kinetic term of Grand Unified Theories (GUTs) may capture effects of quantum gravity or string compactification. Such operators modify the usua…
Gaugino mass non-universality in an SO(10) supersymmetric Grand Unified Theory: low-energy spectra and collider signals
Subhaditya Bhattacharya, Joydeep Chakrabortty
We derive the non-universal gaugino mass ratios in a supergravity (SUGRA) framework where the Higgs superfields belong to the non-singlet representations {\bf 54} and {\bf 770} in…
