In this review, we present a derivation of the on-shell renormalization conditions for scalar and fermionic fields in theories with and without parity conservation. We also discuss the specifics of Majorana fermions. Our approach only assumes a canonical form for the renormalized propagators and exploits the fact that the inverse propagators are nonsingular in [Formula: see text], where [Formula: see text] is the external four-momentum and [Formula: see text] is a pole mass. In this way, we obtain full agreement with commonly used on-shell conditions. We also discuss how they are implemented in renormalization.

Missing Transverse Momentum

We present the MadAnalysis 5 implementation of the heavily charged gauge boson search to recast the analysis of its decay into one charged lepton and missing transverse momentum. Signal events describing [Formula: see text] ([Formula: see text] or [Formula: see text]) at [Formula: see text] TeV in the sequential standard model are generated by the MadGraph5_aMC@NLO at leading order. The corresponding signal cross-sections for both electron and muon channels vary from 195 fb to 0.238 fb depending on the pole mass of the [Formula: see text] boson in the range of 2 TeV to 6 TeV. We validate our implementation by comparing the transverse mass distributions of our signal prediction to those of the ATLAS analysis for an integrated luminosity of 139 fb[Formula: see text].

Mass Definition

We discuss the gauge dependence of fermion mass definition under the on-shell and pole mass renormalization prescriptions. By the two-loop-level calculation of the cross section of the physical process [Formula: see text], we prove for the first time that the on-shell fermion mass renormalization prescription makes physical result gauge-dependent. On the other hand, such gauge dependence does not appear in the result of the pole mass renormalization prescription. Our calculation also implies that the difference of physical results between the two mass renormalization prescriptions cannot be neglected at two-loop level.
