大质量引力理论中的单圈发散

One-loop divergences in massive gravity theory

Ioseph L. Buchbinder, Dante D. Pereira, Ilya L. Shapiro

摘要:

计算了最近提出的无虚影的大质量引力模型的单圈发散,其中作用量依赖于度规场和外张量场f。通过辅助张量场的引入,将质量项的非多项式结构简化为更标准的形式,并在量子计算后将其置于壳层上。正如人们所预料的那样,反项并不再现经典作用量的形式。而且,其结果在f中具有幂级数的形式.

英文摘要:

The one-loop divergences are calculated for the recently proposed ghost-free version of massive gravity, where the action depends on both metric and external tensor field f. The non-polynomial structure of the massive term is reduced to a more standard form by means of auxiliary tensor field, which is settled on-shell after quantum calculations are performed. As one should expect, the counterterms do not reproduce the form of the classical action. Moreover, the result has the form of the power series in f.
