论文摘要
我们研究了替代性左右模型（ALRM）中中性s中性双β衰减（$0νββ$）和瘦素发生的可能性。与通常的左右对称模型不同，ALRM具有主要右手中微子，该中微子不带任何收费。此外，在这张图片中，颜色夸克和带电的舔子通过额外的左手标量场获得质量，而不是通常的双打。这些功能共同通过矢量 - 标准（$ wh $）调解共同为$0νβ$产生重大贡献。对于中等的相关电荷Higgs玻色子（$ M_ {h_1^\ pm} \ sim 200 $ GEV） $^{76} $ ge和$^{136} $ XE，均在未来实验预期的敏感性之内。引起右撇子中微子衰变引起的共鸣诱导生成，可能是产生正确的男性生成的所需顺序，$ε\ sim \ sim 10^{ - 6} $，用于小零相，而没有任何微调。
We investigate the possibility of neutrinoless double beta decay ($0νββ$) and leptogenesis within the Alternative Left-Right Model (ALRM). Unlike the usual left-right symmetric model, ALRM features a Majorana right-handed neutrino which does not carry any charge. Further, in this picture the down-type quark and the charged leptons receive mass through the additional left-handed scalar field, rather than the usual doublet. Together, these features conspire to generate significant contributions to the $0νββ$ through vector-scalar ($WH$) mediation. For moderate masses of the relevant charged Higgs boson ($M_{H_1^\pm}\sim 200$ GeV), the half-life of $T_{\frac{1}{2}}^{WH}$ is $\sim 3\times 10^{26}~{\rm yrs}$ for both the case of $^{76}$Ge and $^{136}$Xe, well within the sensitivity expected by future experiments. Invoking the resonant leptogenesis, CP violation arising from the right-handed neutrino decay could be the required order to generate the correct baryogenesis, $ε\sim 10^{-6}$, for small Dirac phases and without any fine tuning.
