SUSY规范理论中的积群S-限制

Product Group S-Confinement in SUSY Gauge Theories

Benjamin Lillard

摘要:

基于一个反对称物质场和四种夸克的模型,我们提出了一套新的具有乘积规范群和无树能级超势的s-限制理论。对于每个产品组,我们找到一组规范不变的运营商,满足特胡夫特异常匹配条件,我们确定了动态生成的超势再现经典的运营商之间的约束。这些乘积规范理论中的几个在不破坏手征对称性的情况下限制,即使在经典模空间被量子修改的情况下。这些结果可能是有用的复合模型的建设,特别是在小介子运营商不存在的情况下,或与多个自然的能量尺度的理论,并可能提供新的方法来打破超对称动态。

英文摘要:

We propose a new set of s-confining theories with product gauge groups and no tree-level superpotential, based on a model with one antisymmetric matter field and four flavors of quarks. For each product group we find a set of gauge-invariant operators which satisfy the 't Hooft anomaly matching conditions, and we identify the dynamically generated superpotential which reproduces the classical constraints between operators. Several of these product gauge theories confine without breaking chiral symmetry, even in cases where the classical moduli space is quantum-modified. These results may be useful for composite model building, particularly in cases where small meson operators are absent, or for theories with multiple natural energy scales, and may provide new ways to break supersymmetry dynamically.
