| dc.description | The observed light neutrinos may be related to the existence of new heavy neutrinos in the spectrum of the SM. If a pair of heavy neutrinos has nearly degenerate masses, then CP violation from the interference between tree-level and self-energy graphs can be resonantly enhanced. We explore the possibility of observing CP asymmetries due to this mechanism at the LHC. We consider a pair of heavy neutrinos N_{1,2} with masses ranging from 100 to 500 GeV and a mass-splitting Δm_N = m_{N_2}-m_{N_1} comparable to their widths Γ_{N_{1,2}}. We find that for Δm_N ~ Γ_{N_{1,2}}, the resulting CP asymmetries can be very large or even maximal and therefore, could potentially be observed at the LHC. | |
