我们讨论了在大型强子对撞机上产生和衰变重右手中微子时引起的轻子味破坏过程。这些粒子出现在标准模型的左右对称延伸中，作为中微子质量产生的信使，并且可以具有TeV级的质量。我们确定了右手中微子混合矩阵的预期灵敏度，以及右手规范玻色子和重中微子质量的预期灵敏度。通过比较LHC和搜索低能LFV过程的灵敏度，我们确定了参数空间的有利区域，以探索低能和高能LFV之间的互补性。
We discuss lepton flavour violating processes induced in the production and decay of heavy right-handed neutrinos at the LHC. Such particles appear in left-right symmetrical extensions of the Standard Model as the messengers of neutrino mass generation, and can have masses at the TeV scale. We determine the expected sensitivity on the right-handed neutrino mixing matrix, as well as on the right-handed gauge boson and heavy neutrino masses. By comparing the sensitivity of the LHC with that of searches for low energy LFV processes, we identify favourable areas of the parameter space to explore the complementarity between LFV at low and high energies.
