Quark Flavor Mixings from Hierarchical Mass Matrices
Rohit Verma, Shun Zhou
In this paper, we extend the Fritzsch ansatz of quark mass matrices while retaining their hierarchical structures and show that the main features of the Cabibbo-Kobayashi-Maskawa (…
Lepton textures and neutrino oscillations
Rohit Verma
Systematic analyses of the textures arising in lepton mass matrices have been carried out using unitary transformations and condition of naturalness for the Dirac and Majorana neut…
Polytropic bulk viscous cosmological model with variable G and Λ
Rishi Kumar Tiwari, Mukesh Sharma, Sonia Sharma
We consider a Bianchi type-I Polytropic bulk viscous fluid cosmological model with variable G and Λ. To get a deterministic model, we assume some conditions of A, B, C, and polytro…
Generic lepton mass matrices and neutrino oscillations
Rohit Verma
Several intriguing aspects of neutrino oscillation phenomenology like the origin of small neutrino masses, the absolute neutrino mass scale, the neutrino mass hierarchy, i.e. norma…
Lower bound on neutrino mass and possible CP violation in neutrino oscillations
Rohit Verma
The phenomenology of the most general lepton mass matrices obtained through weak basis transformations has been discussed. Using a hierarchical parametrization of these mass matric…
Minimal Weak Basis Textures and Quark Mixing Data
Rohit Verma
The phenomenology of most general quark mass matrices with minimum of three texture zeros obtained through weak basis (WB) transformations has been discussed within the framework o…
