有限模对称的广义物质宇称

Generalized Matter Parities from Finite Modular Symmetries

Tatsuo Kobayashi, Satsuki Nishimura, Hajime Otsuka, Morimitsu Tanimoto, Kei Yamamoto

摘要:

我们通过源于有限模对称性$Γ_N$的离散对称性对标准模型的超对称扩展进行分类。由于有限模对称超对称理论$Γ_N$中的所有耦合都是由具有偶模权的全纯模形式描述的,因此可重整化和不可重整化的算子如重子和轻子数违反算子受到严格的限制。从具有模权$1/M$的多重态的模变换中,我们发现了$\mathbb{Z}_{2M}$对称性,包括广义重子宇称、广义轻子宇称、$R$宇称、$\mathbb{Z}_3$重子三重性和$\mathbb{Z}_6$质子六重性.这种$\mathbb{Z}_{2M}$对称性与CP变换一起被扩大到$\mathbb{Z}_{2M} \rtimes \mathbb{Z}_2^{\text{CP}}$对称性。

英文摘要:

We classify a supersymmetric extension of the Standard Model by discrete symmetries originating from finite modular symmetries $Γ_N$. Since all the couplings in supersymmetric theories of finite modular symmetries $Γ_N$ are described by holomorphic modular forms with even modular weights, renormalizable and non-renormalizable operators such as baryon- and/or lepton-number violating operators are severely constrained. From the modular transformation of matter multiplets with modular weight $1/M$, we find $\mathbb{Z}_{2M}$ symmetries, including the generalized baryon and lepton parities, $R$-parity, $\mathbb{Z}_3$ baryon triality and $\mathbb{Z}_6$ proton hexality. Such $\mathbb{Z}_{2M}$ symmetries are enlarged to $\mathbb{Z}_{2M} \rtimes \mathbb{Z}_2^{\text{CP}}$ symmetries together with the CP transformation.
