超对称模型中的高质量轴子

High Quality Axion in Supersymmetric Models

Gongjun Choi, Tsutomu T. Yanagida

摘要:

在这项工作中,我们讨论了如何使用的对称性,以及在物理学的动机超越标准模型(BSM)可以保证高质量的轴子。我们避免引入对称性,只用于解决轴子质量问题。相反,我们依赖于BSM中的其他问题所激发的对称性:超对称性,$U(1)_{\rm B-L}$和离散R对称性$Z_{NR}$。我们发现,这些保证了高品质的轴子之间的相互作用,即使引力子的质量和轴子衰减常数大$m_{3/2}=\mathcal{O}(10){\rm TeV}$和$F_{a}=\mathcal{O}(10^{15}){\rm GeV}$分别。这项工作的关键点依赖于MSSM的混合异常$Z_{NR}-[SU(2)_{L}]^{2}$和$Z_{NR}-[SU(3)_{c}]^{2}$的贡献是不够的测量$N\neq6$的$Z_{NR}$,这需要引入新的物质场的观察。我们做了介绍,以实现零混合异常,这在逻辑上支持所需的足够大的$N$为$Z_{NR}$。这种机制有效地使$Z_{NR}$等于$U(1)_{R}$,从而提供了一个逻辑完整的解决方案的轴子质量问题。

英文摘要:

In this work, we discuss how the use of the symmetries well motivated in physics beyond the Standard model (BSM) can guarantee the high quality axions. We avoid to introduce symmetries only useful for addressing the axion quality problem. Rather, we rely on symmetries well motivated by other issues in BSM: supersymmetry, $U(1)_{\rm B-L}$ and the discrete R-symmetry $Z_{NR}$. We show that the interplay among these guarantees the high quality of the axion even for the gravitino mass and axion decay constant as large as $m_{3/2}=\mathcal{O}(10){\rm TeV}$ and $F_{a}=\mathcal{O}(10^{15}){\rm GeV}$ respectively. The key point of this work relies on the observation that the MSSM contribution to the mixed anomalies $Z_{NR}-[SU(2)_{L}]^{2}$ and $Z_{NR}-[SU(3)_{c}]^{2}$ is not enough for gauging $Z_{NR}$ for $N\neq6$, which necessitates the introduction of new matter fields. We make the introduction to achieve zero mixed anomalies, which logically supports a desired large enough $N$ for $Z_{NR}$. This mechanism effectively makes $Z_{NR}$ equal to $U(1)_{R}$ and thus offers a logically complete solution to the axion quality problem.
