New Production Mechanism for Heavy Neutrinos at the LHC
We study a new production mechanism for heavy neutrinos at the LHC, which dominates over the usually considered s-channel W-exchange diagram for heavy-neutrino masses larger than 100-200 GeV. The new mechanism is infrared-enhanced by t-channel W\gamma-fusion processes. This has important implication...
