TASI: Standard Model & Neutrino Masses
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, w...
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...
متن کاملNeutrino masses within the minimal supersymmetric standard model.
We investigate the possibility of accommodating neutrino masses compatible with the MSW study of the Solar neutrino deficit within the minimal supersymmetric Standard Model. The “gravity-induced” seesaw mechanism based on an interplay of nonrenormalizable and renormalizable terms in the superpotential allows neutrino masses mν ∝ mu/MI , with mu the corresponding quark mass and MI ≃ 4 × 1011 GeV...
متن کاملLee Wick Dark Energy
We consider the cosmological application of Lee-Wick theory where a field has a higher derivative kinetic operators. The higher derivative term can be eliminated by introducing a set of auxiliary fields. We investigate the cosmological evolutions of these fields as a candidate of dark energy. This model has the same structure as so called “quintom’ model except the form of potentials and the si...
متن کاملRadiatively Induced Neutrino Masses and Large Higgs-Neutrino Couplings in the Standard Model with Majorana Fields
The Higgs sector of the Standard Model (SM) with one right-handed neutrino per family is systematically analyzed. In a model with intergenerational independent mixings between families, we can account for very light neutrinos acquiring Majorana masses radiatively at the first electroweak loop level. We also find that in such a scenario the Higgs coupling to the light–heavy neutrinos and to the ...
