    "abstract": "A Wilsonian renormalization group (WRG) equation for nuclear current\noperators in two-nucleon systems is derived. Nuclear current operators relevant\nto low-energy Gamow-Teller transitions are analyzed using the WRG equation. We\nemploy the axial two-body current operators from phenomenological models and\nheavy-baryon chiral perturbation theory, which are quite different from one\nanother in describing small scale physics. After reducing the model space of\nthe operators using the WRG equation, we find that there still remains a\nsignificant model dependence at \\Lambda = 200 MeV, where \\Lambda is the sharp\ncutoff specifying the size of the model space. A model independent effective\ncurrent operator is found at a rather small cutoff value, \\Lambda = 70 MeV. By\nsimulating the effective current operator at \\Lambda=70 MeV, we obtain a\ncurrent operator based on a pionless theory, thereby arguing an equivalence\nrelation between nuclear current operators of phenomenological models and those\nof effective field theories.",
