| Abstract | |
In this work, we use published results by the ATLAS Collaboration collected at LHC Run 2 at a center-of-mass energy of root s p= 13 TeV with an integrated luminosity of 139 fb(-1) to derive lower-mass limits on the Z' gauge boson associated with the B-L gauge symmetry. Using dilepton data, we find that M-Z'> 4 TeV (6 TeV) for g(B-L) = 0.1 (g(B-L) = 0.5) in the absence of invisible decays. Once invisible decays are turned on, these limits are substantially relaxed. Assuming an invisible branching ratio of BRinv = 0.9, the LHC bound is loosened up to M-Z'> 4.8 TeV for g(B-L) = 0.5. This analysis confirms that the LHC is able to impose stricter constraints than the bounds established by experiments at LEP. We also estimate the projected High-Luminosity LHC bounds at root s = 14 TeV and a planned integrated luminosity of L = 3 ab(-1)that will probe Z' masses up to 7.5 TeV. (AU) | |
