论文摘要
在这封信中，我们通过分析地计算了共形对称性对O（$ n $）$ λϕ^{4} $无质量标量场理论的辐射校正对振幅比率的效果，以探测两尺度因素的普遍性假设。为此，我们采用了三种独立且独立的现场理论重新归一化组方法。通过三种不同的方法计算，获得的幅度比值相同，从而显示它们的通用特征。此外，它们与在扁平时空中获得的相同，然后满足两个规模的因子普遍性假设。
In this Letter we compute analytically the effect of conformal symmetry on the radiative corrections to the amplitude ratios for O($N$) $λϕ^{4}$ massless scalar field theories in curved spacetime for probing the two-scale-factor universality hypothesis. For that we employ three distinct and independent field-theoretic renormalization group methods. The amplitude ratios values obtained are identical when computed through the three distinct methods, thus showing their universal character. Furthermore, they are the same as that obtained in flat spacetime, then satisfying the two-scale-factor universality hypothesis.
