Tribimaximal mixing and leptogenesis in a seesaw model
Riazuddin
It is pointed out that if a neutrino mass matrix for right-handed neutrinos in seesaw mechanism has mu -tau symmetry and total lepton number L_{e}+L_{μ}+L_τ remains constant (not z…
model for electroweak unification and sterile neutrinos
Riazuddin, Fayyazuddin
Some of basic problems in neutrino physics such as new energy scales, the enormous gap between neutrino masses and the lightest charged fermion mass, possible existance of sterile…
An SU(3) symmetry for light neutrinos
Riazuddin
It is proposed that light neutrinos form a triplet in a global SU(3) symmetry in mass eigenstate basis. Assuming that the SU(3)symmetry is broken in the direction (-alambda_{3}+fra…
Neutrino flavor mixing in an SU(3) symmetry for light neutrinos
Riazuddin
It is proposed that light neutrinos form a triplet in a global SU(3) flavor symmetry. Within this framework, a symmetry principle predicts sin^2 theta_{23}=0.5 and gives the so cal…
Neutrinos: recent developments and origin of neutrino mass matrix
Riazuddin
Certainly one of the most exciting areas of research at present is neutrino physics. The neutrinos are fantastically numerous in the universe and as such they have bearing on our u…
Particle Aspects of Cosmology and Baryogenesis
Riazuddin
An introduction to particle aspects of cosmology with particular refrence to primordial nucleosynthesis, dark matter and baryogenesis is provided. In particular, various scenarios-…
