Abstract

The weak decay processes known from early times are all described by charged-current interactions. As given in (2.6), the charged current is the sum of leptonic and hadronic currents:
$${J_\mu } = J_{_\mu }^{(l)} + J_{_\mu }^{(h)} $$
(3.1)
, where
$$J_{_\mu }^{(l)} = \overline {{v_e}} {\gamma _\mu }(1 - {\gamma _5}){e^ - } + \overline {{v_\mu }} {\gamma _\mu }(1 - {\gamma _5}){\mu ^ - } + \overline {{v_\tau }} {\gamma _\mu }(1 - {\gamma _5}){\tau ^ - }$$
(3.2)
and
$$J_{_\mu }^{(h)} = (\overline u ,\overline c ,\overline t ){U_q}{\gamma _\mu }(1 - {\gamma _5})(\begin{array}{*{20}{c}} d \\ s \\ b \\ \end{array} ) $$
(3.3)

    This treatment is invalid for relativistic wave functions, which are singular at the origin. More appropriately, the Fermi function is given by the wave functions at the nuclear radius rather than at the origin.Google Scholar

    This is due to a somewhat tricky, but lucky situation. The cross section for the neutrino flux other than B neutrinos is solely determined by the GT(gs), which is well determined. For the B neutrino capture cross section a large change from García et al.’s B(GT) to Trinder et al.’s B(GT) is mostly a redistribution of the GT strengths at low-lying levels. It is fortunate that the first excited level of A is located above the maximum energies of all solar neutrino fluxes other than B neutrinos and that the GT strength to the first excited state is estimated by subtraction from the total decay rate, which is well constrained. The calculation of Kuramoto et al. takes into account the large GT strengths for E > 5 MeV levels, as expected from the (pn) experiment.Google Scholar

    See also Butler and Chen [484], who used nucleon-nucleon effective field theory to calculate νd cross sections. In their calculation, however, there is one free parameter (an isovector axial two-body matrix element), and the results agree with those of either Kubodera et al. or Haxton et al. depending on the choice of this parameter. The calculation is limited to a low-energy region > 20 MeV. This contrasts with the earlier conclusion of Ying et al. [482], which is ascribed to an error in their computer code [473,483].Google Scholar
