We study the new physics contributions to neutrinoless double beta decay ($0\nu \beta \beta$) in a TeV scale left-right model with spontaneous D-parity breaking mechanism where the values of the $SU{(2)}_L$ and $SU{(2)}_R$ gauge couplings, $g_L$ and $g_R$ are unequal. Neutrino mass is generated in the model via gauge extended inverse seesaw mechanism. We embed the model in a non-supersymmetric $SO(10)$ GUT with a purpose of quantifying the results due to the condition $g_L\ne g_R$. We compare the predicted numerical values of half life of $0\nu \beta \beta$ decay, effective Majorana mass parameter and other lepton number violating parameters for three different cases; (i) for manifest left-right symmetric model ($g_L=g_R$), (ii) for left-right model with spontaneous D parity breaking ($g_L\ne g_R$), (iii) for Pati-Salam symmetry with D parity breaking ($g_L\ne g_R$). We show how different contributions to $0\nu \beta \beta$ decay are suppressed or enhanced depending upon the values of the ratio $\frac{g_R}{g_L}$ that are predicted from successful gauge coupling unification.

我们研究了新的物理学对中微子双β衰变（$0\nu \beta \beta$）在具有自发D奇偶性打破机制的TeV尺度左右模型中， $\mathrm{小号}ü{（2）}_{\mathrm{大号}}$ 和 $\mathrm{小号}ü{（2）}_{\mathrm{[R}}$ 液力偶合器 $G_{\mathrm{大号}}$ 和 $G_{\mathrm{[R}}$是不平等的。中微子质量是通过量规扩展的反向跷跷板机制在模型中生成的。我们将模型嵌入到非超对称中$\mathrm{小号}Ø（10）$ GUT旨在根据条件对结果进行量化 $G_{\mathrm{大号}}\ne G_{\mathrm{[R}}$。我们比较了半衰期的预测数值$0\nu \beta \beta$在三种不同情况下的衰减，有效马约拉纳质量参数和其他轻子数违反参数；（i）对于清单左右对称模型（$G_{\mathrm{大号}}=G_{\mathrm{[R}}$），（ii）对于自发D奇偶性破损的左右模型（$G_{\mathrm{大号}}\ne G_{\mathrm{[R}}$），（iii）具有D奇偶校验破损的Pati-Salam对称性（$G_{\mathrm{大号}}\ne G_{\mathrm{[R}}$）。我们展示了对$0\nu \beta \beta$ 根据比率值抑制或增强衰减 $\frac{G_{\mathrm{[R}}}{G_{\mathrm{大号}}}$ 从成功的量规耦合统一预测。
