Heavy Majorana neutrinos at a very large electron-proton collider
F. M. L. Almeida, Y. A. Coutinho, J. A. Martins Simões +1
We study the discovery potential for detecting new neutral heavy Majorana leptons as suggested by some extentions of the Standard Model in recently proposed electron-proton collide…
