摘要:

我们研究了非超对称SU(N)规范理论的规范动力学,其特征是同时存在根据两种不同的基本规范群表示变换的费米子物质。我们绑定的区域的味道和颜色,可以产生一个物理红外固定点。作为一个一致性检查,我们恢复以前调查的共形窗口的界限时,限制到一个单一的物质表示。早期的共形窗可以想象成现在新的共形房子的一部分。我们预言了红外不动点处的非微扰反常维数。我们进一步研究了在凝聚体中加入质量项对共形手征动力学的影响,并构造了最简单的瞬子诱导的有效拉格朗日项。

英文摘要:

We investigate the gauge dynamics of nonsupersymmetric SU(N) gauge theories featuring the simultaneous presence of fermionic matter transforming according to two distinct representations of the underlying gauge group. We bound the regions of flavors and colors which can yield a physical infrared fixed point. As a consistency check we recover the previously investigated conformal windows bounds when restricting to a single matter representation. The earlier conformal windows can be imagined to be part now of the new conformal house. We predict the nonperturbative anomalous dimensions at the infrared fixed points. We further investigate the effects of adding mass terms to the condensates on the conformal house chiral dynamics and construct the simplest instanton induced effective Lagrangian terms.
