ggF production of the heavy neutrinos from Higgs and bosons. can be prompt when giving an enhancement to the production from the ggF channel. For , off-shell Higgs produces final state. Similarly off-shell can also produce final state when . For the Higgs mediated case, top quark loop will contribute dominantly whereas for the case all contributions coming from the quarks will be counted according to its coupling with the quarks.
