Hitting Bottomonium

Abstract

Introduction

In a fit of childishness, I came across the term Bottomonium referring to Upsolon flavorless mesons.  Some fast and loose internet research attributed the original discovery to Leon Lederman et. al. in 1977.  A peak appeared at 9.5Gev in what I interpreted as a fixed target experiment.  I then looked for the same peak in the LHC data.

Procedures

Using provided 2-110 GeV dimuon data set I looked for a discernible peak in mass.  I did not explore data attributed to Z or W masses.  

Results

The initial 2-110 GeV mass plot shows a peak at 9.5GeV.  Zooming in on the 7-15GeV range reveals peaks at both 9.5 and 10 GeV.

Discussion and Conclusions

While I started my hunt for rather child-like reasons, I was able to tease out Bottomonium from the provided dimuon data set. This relationship should also show up in dielectron events upon further study.
