中国物理学会高能物理分会第十四届全国粒子物理学术会议（2024）

For loops with UV divergences, finite physical results obtained via infinity − infinity mean the physical transition amplitudes of loops are not mathematically well-defined. In this talk, a new method of UV-free scheme will be introduced to derive loop results without UV divergences. It provides a new perspective to the hierarchy problem of Higgs mass without fine-tuning within the Standard Model. In addition, how to describe loop corrections is a fundamental challenge in the quantization of Einstein gravity. Here we give it a try, and the result seems to be effective for graviton loops. This indicates that both loops of the renormalizable Standard Model and the non-renormalizable Einstein gravity can be described by the new method.
