我们研究了维度正则化在光锥规范弦场论中的作用。我们表明,它是没有必要添加一个接触项的弦场论作用作为计数器项在这个正则化至少在树的水平。我们还研究了非临界维数下玻色子理论的单圈振幅,并证明了它们是模不变的。
We study how the dimensional regularization works in the light-cone gauge string field theory. We show that it is not necessary to add a contact term to the string field theory action as a counter term in this regularization at least at the tree level. We also investigate the one-loop amplitudes of the bosonic theory in noncritical dimensions and show that they are modular invariant.
