英文摘要The neutrinoless double-beta (0 nu beta beta) decay is a unique process used to identify the Majorana nature of massive neutrinos, and its rate depends on the size of the effective Majorana neutrino mass < m >(ee). We put forward a novel 'coupling-rod' diagram to describe < m >(ee) in the complex plane, by which the effects of the neutrino mass ordering and CP-violating phases on < m >(ee) are intuitively understood. We show that this geometric language allows us to easily obtain the maximum and minimum of vertical bar < m >(ee)vertical bar. It remains usable even if there is a kind of new physics contributing to < m >(ee), and it can also be extended to describe the effective Majorana masses < m >(e mu), < m >(e tau), < m >(mu mu), < m >(mu tau), and < m >(tau tau) which may appear in some other lepton-number violating processes.
