How to add a sample in NUISANCE

This is a step-by-step guide on how to add samples into the NUISANCE framework.

Using: NUISANCE v1r0, NEUT 5.3.6

For this tutorial I'll be adding the T2K CC1pi+ H2O data. The data comes from http://t2k-experiment.org/results/nd280data-numu-cc1pi-xs-on-h2o-2015/ and https://arxiv.org/abs/1605.07964. The data is supplied both in a ROOT file and a number of .csv files; I'll be using the ROOT file here.

The T2K CC1pi+ H2O data release contains various distributions in FIG 4. In this tutorial I'll look at adding one kinematic distribution and one derived distribution: p_mu and E{rec}_nu.

Examining the data and choosing distributions

Finding the neutrino flux and generating events

The first issue at hand is to find the flux for the experiment. If we don't have this (or its very difficult to find), there is simply no way to reproduce the results (unless the measurement is a total cross-section without any phase space cuts).

A quick search through the document finds it is documented in reference [12]. You could also find it in our ExperimentFlux flux list?.
