共形手性动力学

Conformal Chiral Dynamics

Francesco Sannino

摘要:

我们研究了规范理论的手征动力学,发展了一个红外稳定的不动点。我们确定了双线性费米子凝聚体的基础费米子质量和它的反常尺寸的依赖。我们介绍了瞬子的贡献,并研究它们如何影响附近的不动点的动力学。我们推广了Gell-Mann Oakes Renner关系,并建议用它来揭示基础规范理论的红外不动点的存在。我们的研究结果有直接的影响建设明智的扩展的标准模型的粒子相互作用和强耦合理论的相图的一般理解。

英文摘要:

We investigate the chiral dynamics of gauge theories developing an infrared stable fixed point. We determine the dependence of the bilinear fermion condensate on the underlying fermion mass and its anomalous dimension. We introduce the instanton contributions and investigate how they affect the dynamics near the fixed point. We generalize the Gell-Mann Oakes Renner relation and suggest to use it to uncover the presence of an infrared fixed point of the underlying gauge theory. Our results have an immediate impact on the construction of sensible extensions of the Standard Model of particle interactions and the general understanding of the phase diagram of strongly coupled theories.
