We show some results concerning the renormalization group (RG) invariance of the nucleon‐nucleon (NN) interaction in pionless effective field theory at next‐to‐leading order (NLO), using a non‐relativistic Callan‐Symanzik equation (NRCS) for the driving term of the Lippmann‐Schwinger (LS) equation with three recursive subtractions. The phase‐shifts obtained for the RG evolved potential are same as those for the original potential, apart from relative differences of order 10−15.
