Abstract
In the context of Left-Right symmetry, we revisit the Keung-Senjanovi\'{c} production of right-handed $W_R$ bosons and heavy neutrinos $N$ at high energy colliders. We develop a multi-binned sensitivity measure and use it to estimate the sensitivity for the entire range of $N$ masses, spanning the standard and merged prompt signals, displaced vertices and the invisible $N$ region. The estimated sensitivity of the LHC with 300/fb integrated luminosity ranges from 5 to beyond 7 TeV, while the future 33(100) TeV collider's reach with 3/ab extends to 12(26) TeV.
Highlights
The Standard Model (SM) of fundamental interactions continues to be experimentally verified, and yet we are short of having evidence for a mechanism providing mass to the neutrinos
The scale of breaking is not predicted, the Large Hadron Collider (LHC) would be especially fit for probing this scenario, if the mass of the new RH gauge boson WR were in the TeV range
The bottom line is, there remains a significant potential to discover the WR at the LHC or future colliders, with the high scale hinted by tensions in the kaon sector [15]
Summary
The Standard Model (SM) of fundamental interactions continues to be experimentally verified, and yet we are short of having evidence for a mechanism providing mass to the neutrinos. The bottom line is, there remains a significant potential to discover the WR at the LHC or future colliders, with the high scale hinted by tensions in the kaon sector [15] The golden such channel is the Keung-Senjanović (KS). The mN region below ∼20 GeV is relevant for phenomenology because of the connection between the KS process at the LHC and the new physics contributions to neutrinoless double beta decay, as studied in [32,33,34].
