Partial conservation of axial current (PCAC) and the decay of the charmed F meson into a nucleon pair

It is suggested that measurements of the decay mode F + → p n and of the ratio B( F + → p n )/B( F + → τ +ν τ) provide a useful test of Gell-Mann-Levy's and Nambu's conjecture on the conservation of the axial current in the limit of a massless pion (or equivalently at high energy)....
