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 کاملFermion Masses in the Standard Model*?”
We consider a proposal that the masses of fermions in the Standard Model are determined by dynamical symmetry breaking. Rather than being introduced as arbitrary parameters in the Lagrangian, they are determined self-consistently by the requirement that the proper self-energy vanish on the fermion mass shell. We find in the one-loop approximation that it is possible to generate a heavy top quar...
متن کاملStandard Model Masses and Models of Nuclei
We note an intriguing coincidence in nuclear levels, that the subshells responsible for doubly magic numbers happen to bracket nuclei at the energies of the Standard Model bosons. This could show that these bosons actually contribute to the effective mesons of nuclear models. Dear Grubendol, I want to report you and the fellows of your society about some strange coincidences I have found in nuc...
متن کاملConstituent Quark Masses and the Electroweak Standard Model
Constituent quark masses can be determined quite well from experimental data in several ways and one can obtain fairly accurate values for all six mq. The strong quark-meson coupling g = 2π/ √ 3 arises from the quark-level linear σ model, whereas e and sin θw arise from weak interactions when the heavy MW and MZ are regarded as resonances in analogy with the strong KSFR relation. The Higgs boso...
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...
