Dataset: NLO QCD parton shower matching for $p p \rightarrow e^{+} \nu_e \mu^{-} \bar{\nu}_{\mu} \gamma + X$ simulated using Herwig 7.3 interfaced with VBFNLO 3.0 via BLHA2.

Data files for different observable histograms for NLO QCD parton shower matching for $p p \rightarrow e^{+} \nu_e \mu^{-} \bar{\nu}_{\mu} \gamma + X$ simulated using Herwig 7.3 interfaced with VBFNLO 3.0 via BLHA2.

Parameters:

PDF: CT18LO (LO), CT18NLO (NLO)

Four active scheme.

EW parameters: \begin{align}  m_W & = 80.3770\; {\rm GeV}, \; \Gamma_W = 2.085\; {\rm GeV} \nonumber         \\  m_Z & = 91.1876\; {\rm GeV}, \; \Gamma_Z = 2.495\; {\rm GeV} \nonumber        \\  G_F & = 1.16637\cdot10^{-5}\; {\rm GeV^{-2}}.\end{align}

$\mu_F$ = $\mu_R$ = $m_{\rm EW}$

generation-level cuts: \begin{align}   & p_{T, \ell} > 10\, {\rm GeV},\quad |\eta_{\ell}| < 5.0 \nonumber     \\   & p_{T, \gamma} > 10\, {\rm GeV}, \quad|\eta_{\gamma}| < 5.0, \nonumber \\   & \Delta R_{\ell \gamma} > 0.3,\quad                                  \end{align}

analysis-level cuts\begin{align}   & p_{T, \ell} > 30\, {\rm GeV},\quad |\eta_{\ell}| < 2.5 \nonumber  \\   & p_{T, \gamma} > 30\, {\rm GeV}, \quad|\eta_{\gamma}| < 2.5,\nonumber \\   & \Delta R_{\ell \gamma} > 0.7,\quad   \end{align}

Two different datasets are given:

Herwig + VBFNLO data files

The name of the file describes the corresponding observable,

The columns represent: left bin boundary, right bin boundary, value, low-y error, high-y error.

VBFNLO standalone data files

Name of the observable in the first line inside the file,

columns represent: left bin boundary, right bin boundary, value, y-error
