    Weak axial nuclear heavy meson exchange currents and interactions of solar neutrinos with deuterons

  • Original language description

    Starting from the axial heavy meson exchange currents, constructed earlier in conjunction with the Bethe-Salpeter equation, we first present the axial rho-, omega- and alpha(1)-meson exchange Feynman amplitudes that satisfy the partial conservation of the axial current. Employing these amplitudes, we derive the corresponding weak axial heavy meson exchange currents in the leading order in the 1/M expansion (M is the nucleon mass), suitable for the nuclear physics calculations beyond the threshold energies and with wave functions obtained by solving the Schrodinger equation with one-boson exchange potentials. The constructed currents obey the nuclear form of the partial conservation of the axial current. We apply the space component of these currents incalculations of the cross sections for the disintegration of deuterons by low energy (anti) neutrinos.

    Slabé axiální jaderné mezonové výměnné proudy a a interakce slunečních neutrin s deuterony

  • Czech description

    Na základě axiálních výměnných peroudů s výměnou těžkých mezonů,které byly zkonstruovány dříve pro Bethe-Salpeteronovu rovnici, presentujeme axiální Fenmanovy amplitudy s výměnou rho-omega-a a1 mezonů.S použitím těchto amplitud, odvodíme slabé mezonové proudy, které jsou vhodné pro výpočty v jaderné fyzice.Dále aplikujeme tyto proudy ve výpočtech efektivních průřezů pro reakce slabého štěpení deuteronů nízkoenergetickými neutriny.
