自对偶规范场与畴壁费米子零模

The self-dual gauge fields and the domain wall fermion zero modes

Sadataka Furui

摘要:

本文提出了一种新的库仑规范畴壁费米子系统规范固定,它能减小有效运行耦合和任意动量方向有效质量的涨落,包括圆柱切割区以外的区域,并在RBC/UKQCD合作组的$16^3\times 32\times 16$规范位形中得到了验证。在最低动量点的运行耦合没有显示出红外抑制,并且与从JLab合作中提取的实验数据兼容。动量$p=$ 0.6GeV附近有效质量涨落的来源可能是畴壁费米子零模。

英文摘要:

A new type of gauge fixing of the Coulomb gauge domain wall fermion system that reduces the fluctuation of the effective running coupling and the effective mass of arbitrary momentum direction including the region outside the cylinder cut region is proposed and tested in the $16^3\times 32\times 16$ gauge configurations of RBC/UKQCD collaboration. The running coupling at the lowest momentum point does not show infrared suppression and compatible with the experimental data extracted from the JLab collaboration. The source of the fluctuation of the effective mass near momentum $p=$0.6GeV region is expected to be due to the domain wall fermion zero modes.
