Direct bounds on Left-Right gauge boson masses at LHC Run 2.

While the third run of the Large Hadron Collider (LHC) is ongoing, the underlying theory that extends the Standard Model remains so far unknown. Left-Right Models (LRMs) introduce a new gauge sector, and can restore parity symmetry at high enough energies. If LRMs are indeed realized in nature, the mediators of the new weak force can be searched for in colliders via their direct production. We recast existing experimental limits from the LHC Run 2 and derive generic bounds on the masses of the heavy LRM gauge bosons. As a novelty, we discuss the dependence of the W_R and Z_R total width on the LRM scalar content, obtaining model-independent bounds within the specific realizations of the LRM scalar sectors analysed here. These bounds avoid the need to detail the spectrum of the scalar sector, and apply in the general case where no discrete symmetry is enforced. Moreover, we emphasize the impact on the W_R production at LHC of general textures of the right-handed quark mixing matrix without manifest left-right symmetry. We find that the W_R and Z_R masses are constrained to lie above 2 TeV and 4 TeV, respectively. [ABSTRACT FROM AUTHOR]
