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

$E_{\mu} > 10 {\rm GeV}$

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

$M_{\mu\mu} = \sqrt{(E_{\mu^-}+E_{\mu^+})^2 -(p_{\mu^-}+p_{\mu^+})^2 }$
