Hidden Higgs Particle
A modification of the standard model of electroweak interactions with the
nonlocal Higgs sector is proposed. Proper form of nonlocality makes Higgs
particles unobservable after the electroweak symmetry breaking. They appear
only as a virtual state because their propagator is an entire function. We
discuss some specific consequences of this approach comparing it with the
conventional standard model.Comment: 15 pages, LaTeX, no figure
Longitudinal vector form factors in weak decays of nuclei
The longitudinal form factors of the weak vector current of particles with
spin and isospin are determined by the mass difference
and the charge radii of members of the isotopic doublets. The most promising
reactions to measure these form factors are the reactions with large momentum
transfers involving the spin-1/2 isotopic doublets with a maximum mass
splitting. Numerical estimates of longitudinal form factors are given for
nucleons and eight nuclear spin-1/2 isotopic doublets.Comment: 6 pages. Talk given at the 10th MEDEX'15 meeting Matrix Elements for
