论文摘要
考虑到新的重要细节，重新考虑了带有反对称扭转的弯曲时空中的共形异常。我们首次制定了异常诱导的有效作用的协变量解决方案。协变量的有效作用包括与共形异常中总导数相对应的局部术语。无质量费米对这些术语的贡献的特征是乘法性异常，来自旋转型操作员的两种不同选择。另一方面，异常诱导的作用的非局部部分没有歧义，并且承认低能量的极限类似于度量标准理论中的有效潜力。
The conformal anomaly in curved spacetime with antisymmetric torsion is reconsidered, taking into account new important details. We formulate, for the first time, the covariant solution of the anomaly-induced effective action. The covariant effective action includes local terms corresponding to total derivatives in the conformal anomaly. The contribution of massless fermions to these terms is characterized by multiplicative anomaly, coming from two different choices of doubling for the spinor operator. On the other hand, the nonlocal part of anomaly-induced action is free of ambiguities and admits a low-energy limit, similar to the effective potential in the metric-scalar theory.
