  Hadronic decays of boosted resonances, e.g., top quark jets, at hadronic
super colliders are frequent predictions in TeV-scale extensions of the
Standard Model of Particle Physics. In such scenarios, accurate modeling of QCD
radiation is necessary for trustworthy predictions. We present the automation
of fully differential, next-to-leading-order (NLO) in QCD corrections with
parton shower (PS) matching for an effective Left-Right Symmetric Model (LRSM)
that features $W_R^\pm, Z_R$ gauge bosons and heavy Majorana neutrinos $N$.
Publicly available universal model files require remarkably fewer user inputs
for predicting benchmark collider processes than leading order LRSM
constructions. We present predictions for inclusive $W_R^\pm, Z_R$ production
at the $\sqrt{s} = 13$ TeV Large Hadron Collider (LHC) and a hypothetical
future 100 TeV Very Large Hadron Collider (VLHC), as well as inclusive $N$
production for a hypothetical Large Hadron Electron Collider (LHeC). As a case
study, we investigate at NLO+PS accuracy the properties of heavy neutrino
(color-singlet) jets and top quark (color-triplet) jets from decays of
high-mass $W_R$ bosons at the LHC. Contrary to top jets, we find that the
kinematic properties of heavy neutrinos jets, and in particular jet mass, are
resilient against the effects of parton showers and hard QCD radiation. This
suggests that in searches for neutrino jets, aggressive selection cuts that
would otherwise be inappropriate for top jets can be imposed with minimal
signal loss.
