KEK Theory Seminar (Dr. Richard Ruiz)
In this seminar, we re-examine the discovery potential at hadron colliders of high-mass WR gauge bosons in Left-Right Symmetric Models. We focus on the case where the WR is very heavy compared to the heavy Majorana neutrino N. Present search strategies for WR-N production are not sensitive to this regime due to the breakdown of the collider signature definition: since the neutrinos produced in WR decays are highly boosted, their decays to leptons and jets are highly collimated, forming a single object we call a "neutrino jet."
After exploring the phenomenology of neutrino jets, we consider an alternative WR-N search strategy at hadron colliders. We include QCD corrections to WR production with threshold resummation at NNLL and matched, for the first time, to the threshold-improved parton distributions. We these improvements, we present the discovery potential of neutrino jets at the 13 TeV Large Hadron Collider and a hypothetical future 100 TeV Very Large Hadron Collider.
