我们考虑一个具有测量重子数的模型,当考虑到普朗克尺度以上的引力效应时,该模型可能是渐近安全的。我们研究了该理论中的紫外不动点,并从达到渐近不动点的要求出发,确定了模型在TeV尺度下参数空间的限制条件。假设新的规范对称在TeV尺度上被打破,我们评论了这些限制的现象学含义。
We consider a model with gauged baryon number that may be rendered asymptotically safe when gravitational effects above the Planck scale are taken into account. We study the ultraviolet fixed points in this theory and determine the restrictions on the parameter space of the model at the TeV scale following from the requirement that the asymptotic fixed points are reached. Assuming that the new gauge symmetry is broken at the TeV scale, we comment on the phenomenological implications of these restrictions.
