Bounds on minicharged neutrinos in the minimal standard model.
In the minimal Standard Model (MSM) with three generations of quarks and leptons, neutrinos can have tiny charges consistent with electromagnetic gauge invariance. There are three types of non-standard electric charge, given by Qst + ǫ(Li − Lj), where i, j = e, μ, τ (i 6= j), Qst is standard electric charge, Li is a family-lepton–number, and ǫ is an arbitrary parameter which is put equal to zer...
متن کاملBounds on the Higgs Mass in the Standard Model and the Minimal Supersymmetric Standard Model A
Depending on the Higgs-boson and top-quark masses, M H and Mt, the effective potential of the Standard Model can develop a non-standard minimum for values of the field much larger than the weak scale. In those cases the standard minimum becomes metastable and the possibility of decay to the non-standard one arises. Comparison of the decay rate to the non-standard minimum at finite (and zero) te...
متن کاملBounds on the Higgs Mass in the Standard Model and Minimal Supersymmetric Standard Model
We present bounds on the Higgs mass in the Standard Model and in the Minimal Supersymmetric Standard Model using the effective potential with nextto-leading logarithms resummed by the renormalization group equations, and physical (pole) masses for the top quark and Higgs boson. In the Standard Model we obtain lower bounds from stability requirements: they depend on the top mass and the cutoff s...
متن کاملTriviality bounds in the next to minimal supersymmetric standard model.
We study the implications of the triviality problem for the Higgs masses and other relevant parameters in the Next to Minimal Supersymmetric Standard Model (NMSSM). By means of triviality, a new way to constrain parameters is proposed, and therefore we are able to derive triviality bounds on the heaviest-Higgs mass, the lightest-Higgs mass, the soft SUSY-breaking parameters, and the vacuum expe...
متن کاملNeutrinos and the standard model
Since their ”discovery” by Pauli in 1930, neutrinos have played a key part in confirmation of the structure of the standard model of strong and electroweak interactions. After reviewing ways in which this has been manifested in the past, we discuss areas in which neutrinos continue to play this role.
