Description
简介:张宏浩,中山大学物理学院教授,博士生导师。他于1998-2002年在清华大学物理系读本科,2002-2007年在清华大学物理系读直博,2007年至今在中山大学任教,2010年12月被聘为副教授,2016年6月被遴选为博士生导师,2017年1月被聘为教授。他主要研究粒子物理与场论,特别是暗物质、有效场论、额外维、超出标准模型的新物理等。他的课题组是国际上最早运用有效场论方法对暗物质开展唯象学计算分析的研究小组之一,其在这方面的两篇代表性研究论文获得了国际同行的大量引用。 摘要:Asymptotic safety was originally proposed by Steven Weinberg to find a theory of quantum gravity. Its key ingredient is the existence of a nontrivial ultraviolet (UV) fixed point of the coupling constants of the theory. In this work, we propose a new class of asymptotically safe dark matter models with minimal parameters. We study the phenomenology of the models, and find that they are actually viable in some regions of the parameter space.
