abstract

P odd anapole moment of the deuteron is found in the chiral limit, $m_{\pi} \to 0$. The contact current generated by the P odd pion exchange does not contribute to the deuteron anapole. Being combined with usual radiative corrections to the weak electron -- deuteron interaction, our calculation results in a sufficiently accurate theoretical prediction for the corresponding effective constant $C_{2d}$. The experimental measurement of this constant would give valuable information on the P odd $\pi$NN constant and on the $s$-quark content of nucleons. We calculate also in the same limit $m_{\pi} \to 0$ the deuteron P odd and T odd multipoles: electric dipole moment and magnetic quadrupole moment.
