Derived_quantities module

This module contains the functions to calculate the derived quantities of the HEP dataset. Originally written by David Rousseau, and Victor Estrade.

derived_quantities.DER_data(data)

data is supposed to be clean (no Weight, no eventId etc…) This function directly modifies the dataframe data so make sure to make a copy if you need to keep data

derived_quantities.calcul_int(data)

Calculate the px py pz E components of the particles’ 4 momentum.

Args:

data (pandas.DataFrame): Input data containing the particle properties.

Returns:

pandas.DataFrame: Dataframe with the derived quantities calculated.

derived_quantities.f_DER_deltaeta_jet_jet(data)

Calculate the absolute value of the difference of the pseudorapidity of the two jets Parameters: data (dataframe)

derived_quantities.f_DER_deltar_had_lep(data)

Calculate the delta R between the hadron and the lepton

derived_quantities.f_DER_lep_eta_centrality(data)

Calculate the centrality of the lepton Parameters: data (dataframe)

derived_quantities.f_DER_mass_jet_jet(data)

Calculate the invariant mass of the two jets Parameters: data (dataframe)

derived_quantities.f_DER_mass_transverse_met_lep(data)

Calculate the transverse mass between the MET and the lepton Parameters: data (dataframe)

derived_quantities.f_DER_mass_vis(data)

Calculate the invariant mass of the hadron and the lepton Parameters: data (dataframe)
