Testing a possible W and Z structure at the LHC/CERN

Abstract

One of the first channels to be experimentally analyzed at the LHC is $p+p⟶l^{+}+l^{-}+X$. A resonance in this channel would be a clear indication of a new gauge neutral boson, as proposed in many extended models. In this paper we call attention to the possibility that the new resonance in this channel could have spin zero. A new high mass spin zero state could be a strong indication of the composite nature of the standard model particles. We have made a comparison between spin zero and spin one for the new hypothetical heavy gauge particle production and decays and we show some distributions that can easily identify their spins.
