标题： Neutrinoless double-$β$ decay in TeV scale Left-Right symmetric models

摘要： 在本文中，我们详细研究了在具有TeV尺度右手规范玻色子的左右对称模型中的无中微子双β衰变。这种尺度目前处于对撞机可探测的范围内。 我们讨论了可以对此过程做出贡献的不同图，并确定了当右手中微子也处于TeV尺度时的主要贡献。 我们计算了在假设I型和II型主导的情况下，控制无中微子双β衰变的有效质量的贡献，并讨论了由于额外贡献导致的有效质量的变化。 我们还讨论了最近的Daya-Bay和RENO测量对$\sin^2\theta_{13}$的影响，在不同情景下对有效质量的影响。 显示英文摘要

摘要： In this paper we study in detail the neutrinoless double beta decay in left-right symmetric models with right-handed gauge bosons at TeV scale which is within the presently accessible reach of colliders. We discuss the different diagrams that can contribute to this process and identify the dominant ones for the case where the right-handed neutrino is also at the TeV scale. We calculate the contribution to the effective mass governing neutrinoless double beta decay assuming type-I, and type-II dominance and discuss what are the changes in the effective mass due to the additional contributions. We also discuss the effect of the recent Daya-Bay and RENO measurements on $\sin^2\theta_{13}$ on the effective mass in different scenarios.
