The neutrino dispersion in the magnetized medium was analyzed as a function of the neutrino spin and mass. It was shown that in a super-strong magnetic field plasma contribution to the neutrino energy greatly exceeds the analogous correction in the field-free case.
Production of a massive neutrino-antineutrino pair by a virtual polarized photon in the Weiberg-Salam model with mixing is studied. The rate of the neutrino production by photons with various polarizations is found at values of the magnetic field intensity lower than critical.
The radiation shift of the quark mass in a constant chromomagnetic field at finite temperature and density was calculated. The limiting cases of a weak and a strong chromomagnetic field were considered. It was shown that in a strong field there is no imaginary part in the contribution of the finite density effects to the quark mass shift, and its real part can considerably exceed the corresponding part of the purely field contribution.
The rate of associative production of Higgs and $Z$--bosons by charged leptons in the field of a plane electromagnetic wave of arbitrary intensity and in the constant crossed field is obtained. The cross section is examined as a function of particle energies and external field intensities for various values of the Higgs boson mass. It is shown, that the photoproduction cross section increases logarithmically at super high energies up to the values, that essentially exceed the cross section of the reaction $e^+e^-\to ZH,$ which, at present, is considered as the most probable channel of Higgs boson production.
