\begin{document}$^3P_{0}$\end{document} channel. Another interesting feature is that the \begin{document}$^1S_{0}$\end{document} and \begin{document}$^3P_{1}$\end{document} channels are correlated. Fixing the relevant low energy constants by fitting to the \begin{document}$^1S_{0}$\end{document} phase shifts at \begin{document}$T_\mathrm{lab.}=10$\end{document} and 25 MeV with cutoff values \begin{document}$\Lambda = 400-650$\end{document} MeV, one can describe the \begin{document}$^3P_{1}$\end{document} phase shifts relatively well. In the limit of \begin{document}$\Lambda\rightarrow \infty$\end{document}, the \begin{document}$^1S_0$\end{document} phase shifts become cutoff-independent, whereas the \begin{document}$^3P_{1}$\end{document} phase shifts do not. This is consistent with the Wigner bound and previous observations that the \begin{document}$^{3}P_1$\end{document} channel is best treated perturbatively. As for the \begin{document}$^1P_{1}$\end{document} and \begin{document}$^3S_{1}$\end{document}-\begin{document}$^3D_{1}$\end{document} channels, renormalization group invariance is satisfied."> Renormalizability of leading order covariant chiral nucleon-nucleon interaction -
