EFT($\notpi$)各种场景下的有效射程扩展

Effective range expansion in various scenarios of EFT($\notpi$)

Ji-Feng Yang

摘要:

利用严格解,我们比较了在非微扰区EFT($\notpi$)的三种不同情况下的ERE参数。PSA数据显示,非常规功率计数(如KSW)的情况下,不受欢迎,而一个精心设计的重整化处方,但保持传统的功率计数完好无损似乎更有希望。

英文摘要:

Using rigorous solutions, we compare the ERE parameters obtained in three different scenarios of EFT($\notpi$) 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.
