The Majorana nature of neutrinos may only be experimentally verified via lepton-number violating processes involving charged leptons. We explore the Delta L = 2 like-sign dilepton production at hadron colliders to search for signals of Majorana neutrinos. We find significant sensitivity for resonant production of a Majorana neutrino in the mass range of 10-80 GeV at the current run of the Tevatron with 2 fb(-1) integrated luminosity and in the range of 10-400 GeV at the CERN LHC with 100 fb(-1).
中微子的马约拉纳性质只能通过涉及带电轻子的轻子数违反过程进行实验验证。我们研究强子对撞机中类似同号双轻子产生的ΔL = 2过程，以寻找马约拉纳中微子的信号。我们发现，在Tevatron当前运行且积分亮度为2 fb⁻¹时，对质量范围在10 - 80 GeV的马约拉纳中微子的共振产生有显著敏感性；在欧洲核子研究中心大型强子对撞机（CERN LHC）且积分亮度为100 fb⁻¹时，对质量范围在10 - 400 GeV的马约拉纳中微子的共振产生有显著敏感性。
