TASI: Standard Model & Neutrino Masses
نویسنده
چکیده
Now that we have assembled the pieces, we can write down the Standard Model Lagrangian. It consists of three gauge theories based on the groups SU(3) for color, SU(2) for weak charge, and U(1) for hypercharge, with three independent coupling constants g3, g2, and g1, and three gauge potentials: eight gluons, Gμ , A = 1, 2, . . . , 8, three weak bosons, W a μ , a = 1, 2, 3, and one Hyperon Bμ, with field strengths

The origin of the asymmetry between matter and anti-matter of the Universe has been one of the great challenges in particle physics and cosmology. Leptogenesis as a mechanism for generating the cosmological baryon asymmetry of the Universe has gained significant interests ever since the advent of the evidence of non-zero neutrino masses.

متن کاملModel for Small neutrino masses at the TeV Scale
We propose a model for neutrino mass generation in wich no physics beyond a TeV is required. We extend the standard model by adding two charged singlet fields with lepton number two. Dirac neutrino masses mνD ≤ MeV are generated at the one loop level. Small left handed majorana neutrino masses can be generated via the seesaw mechanism with right handed neutrino masses MR are of order TeV scale....
متن کاملGravitino constraints on models of neutrino masses and leptogenesis
In the supersymmetric extensions of the standard model, neutrino masses and leptogenesis requires existence of new particles. We point out that if these particles with lepton number violating interactions have standard model gauge interactions, then they may not be created after reheating because of the gravitino problem. This will rule out all existing models of neutrino masses and leptogenesi...
متن کاملNeutrino masses and particle physics beyond the standard model
The evidence for non-vanishing neutrino masses from solar and atmospheric neutrinos provides the first solid hint towards physics beyond the standard model. A full reconstruction of the neutrino spectrum may well provide a key to the theoretical structures underlying the standard model such as supersymmetry, grand unification or extra space dimensions. In this article we discuss the impact of a...
