    "abstract": "We use a recently improved version of the chiral nucleon-nucleon potential at\nnext-to-next-to-leading order to calculate the $^1S_0$ pairing gap in\nisospin-symmetric nuclear matter. The pairing potential consists of the\nlong-range one- and two-pion exchange terms and two short-distance NN-contact\ncouplings. We find that the inclusion of the two-pion exchange at\nnext-to-next-to-leading order reduces substantially the cut-off dependence of\nthe $^1S_0$ pairing gap determined by solving a regularised BCS equation. Our\nresults are close to those obtained with the universal low-momentum\nnucleon-nucleon potential $V_{\\rm low-k}$ or the phenomenological Gogny D1S\nforce.",
