量子引力与标量场

Quantum gravity and scalar fields

P. T. Mackay, D. J. Toms

摘要:

本文研究了与引力耦合的标量场的一圈量子化。我们研究了有效作用量中质量(即φ ^2)项出现的发散。我们使用Vilkovisky-DeWitt有效作用量技术,它保证了结果是规范不变的,以及规范条件独立的传统计算相比。我们的最终结果是确定有效行动的完整极点部分。

英文摘要:

In this paper we consider the quantization of a scalar field coupled to gravity at one loop order. We investigate the divergences appearing in the mass (i.e. phi^2) term in the effective action. We use the Vilkovisky-DeWitt effective action technique which guarantees that the result is gauge invariant as well as gauge condition independent in contrast to traditional calculations. Our final result is to identify the complete pole part of the effective action.
