    "abstract": "Recently, we have derived the leading and subleading isospin-breaking\nthree-nucleon forces using the method of unitary transformation. In the present\nwork we extend this analysis and consider the corresponding two-nucleon forces\nusing the same approach. Certain contributions to the isospin-violating one-\nand two-pion-exchange potential have already been discussed by various groups\nwithin the effective field theory framework. Our findings agree with the\npreviously obtained results. In addition, we present the expressions for the\nsubleading charge-symmetry-breaking two-pion exchange potential which were not\nconsidered before. These corrections turn out to be numerically important.\nTogether with the three-nucleon force results presented in our previous work,\nthe results of the present study specify completely isospin-violating nuclear\nforces up to the order $q^5/\\Lambda^5$, where $q$ ($\\Lambda$) denotes the soft\n(hard) scale.",
