摘要:

本文总结了在伴随表象中具有不同数目费米子的SU(2)规范理论的谱和质量反常维数的结果,其中每个Majorana费米子有效地对应于半个Dirac味$N_f$ .标准模型的扩展最相关的例子是超对称杨-米尔斯理论($N_f=1/2$)和最小步行技术色($N_f=2$)。除了这些理论,我们还将考虑$N_f=1$和$N_f=3/2$的情况。结果包括胶球,三重态和单重态介子,和可能的分数带电自旋半粒子的粒子谱。此外,我们将讨论我们最近的结果的质量异常尺寸。

英文摘要:

We summarize our results concerning the spectrum and mass anomalous dimension of SU(2) gauge theories with various numbers of fermions in the adjoint representation, where each Majorana fermion corresponds effectively to half a Dirac flavour $N_f$. The most relevant examples for extensions of the standard model are supersymmetric Yang-Mills theory ($N_f=1/2$) and Minimal Walking Technicolour ($N_f=2$). In addition to these theories we will also consider the cases of $N_f=1$ and $N_f=3/2$. The results comprise the particle spectrum of glueballs, triplet and singlet mesons, and possible fractionally charged spin half particles. In addition we will discuss our recent results for the mass anomalous dimension.
