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

TL;DR

This paper explores the potential for a new spin-zero resonance in the dilepton channel at the LHC, which could indicate a composite nature of standard model particles, and compares it with the spin-one hypothesis.

Contribution

It introduces the possibility of a spin-zero gauge boson resonance at the LHC and compares its signatures with those of a spin-one boson, aiding in experimental identification.

Findings

Distributions that distinguish spin-zero from spin-one resonances.

Potential for a spin-zero resonance to indicate compositeness of standard model particles.

Comparison of production and decay signatures for different spins.

Abstract

One of the first channels to be experimentally analyzed at the LHC is $ p + p \longrightarrow 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.
