论文摘要
我们研究了最小左右对称模型（LRSM）的中微子质量基质中纹理零的现象学意义。由于最大零的可能性减少了该模型的最大参数数量，因此我们仅考虑那些在轻中微子中微子质量矩阵中具有最大纹理零的案例，而dirac Neutrino sutrino suptrino mass mastrix $ m_d $和重型右手（rh）中微子质量（RH）中微子MastIno Mastrino MATSRINO MATSRINIS MASTRINIS MATSRISN MASTRIX $ M_ $ m_ {rr} $ {RR} $ {RR} $ {RR} $ {RR}。然后，我们计算了不同的光中微子参数之间的相关性，然后计算出针对中微子双β衰变（NDBD）的新物理贡献，用于不同的质地零病例。我们发现，对于高于1 GEV的RH中微子质量，对NDBD的新物理贡献可以饱和相应的实验结合。
We studied the phenomenological implications of texture zeros in the neutrino mass matrix of the minimal left-right symmetric model (LRSM). Since the possibility of maximum zeros reduces the maximum number of free parameters of the model making it more predictive, we considered only those cases with maximum possible texture zeros in light neutrino mass matrix $M_ν$, Dirac neutrino mass matrix $M_D$ and heavy right-handed (RH) neutrino mass matrix $M_{RR}$. We then computed the correlations among the different light neutrino parameters and then the new physics contributions to neutrinoless double beta decay (NDBD) for the different texture zero cases. We find that for RH neutrino masses above 1 GeV, the new physics contributions to NDBD can saturate the corresponding experimental bound.
