Cross-fertilising extra gauge boson searches at the LHC

Abstract For the purpose of cross-fertilising currently separate experimental approaches, we connect results of LHC analyses attempting to access the properties of additional W′ and Z′ bosons from Drell-Yan processes. Under theoretical assumptions linking the two new gauge bosons, we take into accou...
