Pad\'e expansion and the renormalization of nucleon-nucleon scattering
  The importance of imposing physical boundary conditions on the $T$-matrix to remove the nonperturbative renormalization prescription dependence is stressed and demonstrated in two diagonal channels, $^1P_1$ and $^1D_2$, with the help of Pad\'e expansion.
