In these lectures we briefly cover some of the main lines of research in particle physics beyond the Standard Model

Beyond the Standard Model

In these lectures I give a short review of the main theoretical ideas underlying the extensions of the Standard Model of elementary particle interactions.

The Standard Model and Beyond

The Standard Model and Beyond

We start with a brief presentation of the Standard Model and the weak neutral current, in view of a discussion of parity-violation in electron-hadron electroweak interactions. We then discuss some limitations of this model, motivating the consideration of larger frameworks such as grand-unification and supersymmetry. We also comment about the possible effects of additional light neutral gauge b...

Beyond The Standard Model

An overview of unified theory models that extend the standard model is given. A scenario describing the physics beyond the standard model is developed based on a finite quantum field theory (FQFT) and the group G=SO(3, 1)⊗SU(3)⊗SU(2)⊗U(1). The field theory is Poincaré invariant, gauge invariant, finite and unitary to all orders of perturbation theory and has a fundamental scale which is chosen ...
