| dc.description | We calculate in chiral perturbation theory the parity-violating two-pion exchange nucleon-nucleon potentials at leading one-loop order. At a distance of $r= m_π^{-1} \simeq 1.4 $fm they amount to about $\pm 16%$ of the parity-violating $1π$-exchange potential. We evaluate also the parity-violating effects arising from $2π$-exchange with excitation of virtual $Δ(1232)$-isobars. These come out to be relatively small in comparison to those from diagrams with only nucleon intermediate states. The reason for this opposite behavior to the parity-conserving case is the blocking of the dominant isoscalar central channel by CP-invariance. Furthermore, we calculate the T-matrix related to the iteration of the parity-violating $1π$-exchange with the parity-conserving one. The analytical results presented in this work can be easily implemented into calculations of parity-violating nuclear observables. | |
