    "abstract": "We calculate the parity-violating nucleon-nucleon potential in heavy-baryon\nchiral perturbation theory up to the next-to-next-to-leading order. The\none-pion exchange comes in the leading order and the next-to-next-to-leading\norder consists of two-pion-exchange and the two-nucleon contact terms. In order\nto investigate the effect of the higher order contributions, we calculate the\nparity-violating asymmetry in $\\vec{n} p \\to d \\gamma$ at the threshold. The\none-pion dominates the physical observable and the two-pion contribution is\nabout or less than 10% of the one-pion contribution.",
