We can conclude that the process of Z boson emission by a neutrino is possible as a perturbative process only in early universe when the expansion factor is much larger than the Z boson mass. 3. Total Probability In this section, we will analyze the situation when the expansion parameter ω...

The covariant Hamiltonian formalism for quantized fields and the relativistic Fock space method, developed in previous papers, are applied to the case of the Z-boson in the Weinberg-Salam theory, and the quantization of the mass of the Z-boson is discussed. An «elementary» Z-boson is as...
A model of a light $Z'$ boson based on gauged $L_\\mu - L_au$ $U(1)$ symmetry is constructed. The $Z'$ boson mass is constrained to be in the range of 0.8 to 1 GeV from Z and $Z'$ mass relation, g-2 of muon, and tau decays. The two body decay $au ightarrow \\mu...
摘要: The mass of Z′ boson is considered in a flavor-independent phenomenological potential model. We have used the low energy parameters and the estimated value so obtained is accessible to experiments at low energies.关键词:Higgs boson potential model Z boson Z′ boson ...
The search for Higgs boson production in association with a W or a Z boson, in the decay channel H→WW∗, is performed with a data sample collected with the ATLAS detector at the LHC in proton-proton collisions at centre-of-mass energi... The search for Higgs boson production in assoc...
