چکیده
We discuss the simplest models for the generation of neutrinos masses at tree level and one-loop level. The realization of the different seesaw mechanisms in the context of renormalizable SU(5) and SO(10) theories is reviewed. A new mechanism for the generation of neutrino masses at one-loop level is presented. We discuss the first realization of the Type III seesaw mechanism in the context of a renormalizable SU(5) theory, called “Adjoint SU(5)".

We point out a Z2 × Z2 symmetry which characterizes uniquely the phenomenologically successful tripartite form leading to a tri-bimaximal mixing in the neutrino mass matrix. We impose this symmetry in a set up including the charged leptons and find that it can accommodate all the possible patterns of lepton masses in the framework of type-I and type-II seesaw mechanism. We also discuss the poss...

Using the experimental result on b → sγ and theoretical result on b → sg, a four -generation SM is analysed to constrain the rephasinginvariant combinations of the CKM matrix and masses of the fourth generation quarks.

We present the Large Hadron Collider (LHC) discovery potential in the Z′ and heavy neutrino sectors of a U(1)B−L enlarged Standard Model also encompassing three heavy Majorana neutrinos. This model exhibits novel signatures at the LHC, the most interesting arising from a Z′ decay chain involving heavy neutrinos, eventually decaying into leptons and jets. In particular, this signature allows one...

Dynamical chiral symmetry breaking and confinement are two crucial features of Quantum Chromodynamics responsible for the nature of the hadron spectrum. These phenomena, presumably coincidental, can account for 98% of the mass of our visible universe. In this set of lectures, I shall present an introductory review of them in the light of the Schwinger-Dyson equations.
