Abstract

Using rigorous solutions, we compare the ERE parameters obtained in three different scenarios of EFT( ) in nonperturbative regime. A scenario with unconventional power counting (like KSW) is shown to be disfavored by the PSA data, while the one with elaborate prescription of renormalization but keeping conventional power counting intact seems more promising.
