手征相互作用减重整化的外围NN散射

Peripheral NN scattering from subtractive renormalization of chiral interactions

Edilson Ferreira Batista, Sergio Szpigel, Varese Salvador Timoteo

摘要:

我们在Lippman-Schwinger(LS)方程中应用五个减法,以进行手征N3 LO核子-核子相互作用的非微扰重整化。在这里,我们计算的非耦合的周边波在重整化尺度之间的相移$0.1~ \rm{fm}^{-1}$和$1 ~ \rm{fm}^{-1}$。在这个范围内,结果是尺度不变的,并且提供了与奈梅亨分波分析的总体一致性,至少达到$E_{\rm{lab}} = 150 ~ \rm{MeV}$,截止值为$Λ= 30~\rm{fm}^{-1}$。

英文摘要:

We apply five subtractions in the Lippman-Schwinger (LS) equation in order to perform a non-perturbative renormalization of chiral N3LO nucleon-nucleon interactions. Here we compute the phase shifts for the uncoupled peripheral waves at renormalization scales between $0.1~ \rm{fm}^{-1}$ and $1 ~ \rm{fm}^{-1}$. In this range, the results are scale invariant and provide an overall goof agreement with the Nijmegen partial wave analysis up to at least $E_{\rm{lab}} = 150 ~ \rm{MeV}$, with a cutoff at $Λ= 30~\rm{fm}^{-1}$.
