## Introduction

In this example, we will draw a plot of invariant mass of di-muon, which come from $H$, for the channel of $vvH$.

## Event selection

The muon+ and muon- candidates are selected by

The di-muon is constructed from the one muon+ and one muon of largest energies. Then the invariant mass is calculated by
