Abstract

This is an imaginary story that could come to pass involving a detector, a Boson, and good resolution. It was written for Snowmass 2013, as a white paper for the New Physics group. The story describes a scenario in which nature has designated the existence of a Left-Right Symmetric Model Z' at a pole mass of 3 TeV, which is observed by analysers through the dilepton decay channel. Signal and Background samples were generated for a proton-proton collider at $\sqrt{s}$ = 14 TeV and $\sqrt{s}$ = 33 TeV, with enough events to represent a dataset of up to 3000 fb$^{-1}$ for each centre of mass energy. These samples were passed through the Delphes fast simulation framework to produce detector reconstructed events. The story is played out from first hints to a well established new discovery with plentiful data, and attempts to capture the journey and excitement that this entails.
