论文摘要

The superallowed Gamow-Teller transition in the doubly-magic-shell nucleus $^{100}$Sn and the high resolution spectral shape analysis in the fourth-forbidden nonunique transition in $^{115}$In indicate as much as $\sim 40\%$ {\it fundamental} quenching in the axial-current coupling constant $g_A$ in nuclei.这可以归因于核培养基中QCD“出现”痕量异常的影响。如果得到证实,这将表明与核培养基中手性尺度对称性一致的核相互作用进行重大改进,并对BSM的$0ν$和$νν$ double $β$衰减产生重大影响。我提出了一个论点,即如此大的异常引起的淬火与隐藏量表的对称性在核培养基中的表现不相容,这是解决此问题的一种可能手段,以隐藏的规模对称性在男性核物质中渗透到正常核物质到巨大的紧凑型明星。

The superallowed Gamow-Teller transition in the doubly-magic-shell nucleus $^{100}$Sn and the high resolution spectral shape analysis in the fourth-forbidden nonunique transition in $^{115}$In indicate as much as $\sim 40\%$ {\it fundamental} quenching in the axial-current coupling constant $g_A$ in nuclei. This can be attributed to an effect of the trace anomaly in QCD "emerging" in nuclear medium. If confirmed, this would signal a major revamping to do in nuclear interactions consistent with chiral-scale symmetry in nuclear medium and a big impact on $0ν$ and $νν$ double $β$ decays for BSM. I present an argument that such a big anomaly-induced quenching is incompatible with how hidden scale symmetry manifests in nuclear medium, A possible means to resolve this issue is discussed in terms of hidden scale symmetry permeating in baryonic matter from normal nuclear matter to massive compact-star matter.
