有效场论中低能质子-质子散射

Low energy proton-proton scattering in effective field theory

Shung-ichi Ando, Jae Won Shin, Chang Ho Hyun, Seung Woo Hong

摘要:

用无介子有效场论研究了低能质子-质子散射。采用维数正则化和MS-bar及功率发散减法进行环计算,计算了1 S 0通道的散射振幅,直到次-次-首阶,并通过有效射程参数确定振幅中出现的低能常数。本文研究了S波质子-质子散射中库仑相互作用与散射长度和有效射程分离的正则化方案和尺度依赖性。

英文摘要:

Low energy proton-proton scattering is studied in pionless effective field theory. Employing the dimensional regularization and MS-bar and power divergence subtraction schemes for loop calculation, we calculate the scattering amplitude in 1S0 channel up to next-to-next-to leading order and fix low-energy constants that appear in the amplitude by effective range parameters. We study regularization scheme and scale dependence in separation of Coulomb interaction from the scattering length and effective range for the S-wave proton-proton scattering.
