多种风格的SU(3)理论中保形性研究的新方法

A novel approach to the study of conformality in the SU(3) theory with multiple flavors

Richard Brower, Anna Hasenfratz, Claudio Rebbi, Evan Weinberg, Oliver Witzel

摘要:

研究了SU(3)理论中多费米子味的自发手征对称性破缺与共形行为之间的转变。我们提出了一个新的策略来研究这种转变。为了探测跃迁,我们没有改变味道的数量,而是提升了费米子子集的质量,使其余的费米子保持在无质量手征极限附近。献给瓦列里·鲁巴科夫院士60岁生日。

英文摘要:

We investigate the transition between spontaneous chiral symmetry breaking and conformal behavior in the SU(3) theory with multiple fermion flavors. We propose a new strategy for studying this transition. Instead of changing the number of flavors, we lift the mass of a subset of the fermions, keeping the rest of the fermions near to the massless chiral limit in order to probe the transition. Dedicated to the 60th birthday of Academician Valery Rubakov.
