    The function creates a ``ParticleList``, selecting particles according to the chosen ``working_point``,
    and decorates each candidate in the list with the nominal Data/MC :math:`\\ell` ID efficiency and
    :math:`\\pi,K` fake rate correction factors and their stat, syst uncertainty, reading the info
    from the Conditions Database (CDB) according to the chosen input global tag (GT).
 
    .. note::
        Particles will **not** be selected if they are outside the Data/MC *efficiency* corrections' phase space coverage
        for the given working point.
        In fact, the threshold value for the PID cut in such cases is set to NaN.
 
    .. warning::
        At the moment, the only supported *binary* lepton identification is against the **pion** hypothesis.
        This implies that, if binary classification is chosen, only :math:`\\pi` fake rate corrections will be added to the
        resulting particle list.
 
    Parameters:
        pdgId (int): the lepton pdg code.
        working_point (str): name of the chosen working point that defines the content of the list. Choose among the above values.
        method (str): the PID method: 'likelihood' or 'bdt'.
        classification (str): the type of classifier: 'binary' (one-vs-pion) or 'global' (one-vs-all).
        lid_weights_gt (str): the name identifier of the global tag with the recommended Data/MC correction weights.
 
                              .. tip::

                                  for info about the recommended global tags.
 
        release (Optional[int]): the major release number of the data and MC campaigns considered.
                                 If specified, it ensures the correct :math:`\\ell` ID variables are used.

                                     for info about lepton identification variables and campaigns.
 
        channel_eff (Optional[str]): the channel used to derive the :math:`\\ell` ID efficiency corrections.
                                     By default, 'combination' is set, meaning they are obtained by combining results
                                     of several hadronic and low multiplicity channels, wherever they overlap.
 
                                     .. tip::

                                         for other possible choices (if any).
 
        channel_misid_pi (Optional[str]): the channel used to derive the :math:`\\pi` fake rate corrections.
        channel_misid_K (Optional[str]): the channel used to derive the :math:`K` fake rate corrections.
        inputListName (Optional[str]): the name of a pre-existing ``ParticleList`` object (defined as a full ``decayString``,
                                       e.g. 'e-:my_input_electrons') of which the standard lepton list will be a subset.
                                       For instance, users might want to apply a Bremsstrahlung correction to electrons first,
                                       which modifies their 4-momentum, and only later define the subset passing the PID selection,
                                       including the appropriate PID weights and uncertainties (which are :math:`p`-dependent).
                                       By default, the standard lepton list is created from all ``Track`` objects in the event.
 
                                       .. warning::
                                           Do **not** apply any PID selection on the input list, otherwise results could be biased.
 
        outputListLabel (Optional[str]): the name of the output lepton list label, i.e.,
                                         the string that follows the particle identifier ('e-:', 'mu-:').
                                         By default, it is assigned as:
                                         ``'{method}_{classification}_{working_point}'``.
 
        trainingModeMulticlass (Optional[``Belle2.ChargedPidMVAWeights.ChargedPidMVATrainingMode``]): enum identifier
                               of the multi-class (global PID) training mode.
                               See `modularAnalysis.applyChargedPidMVA` docs for available options.
        trainingModeBinary (Optional[``Belle2.ChargedPidMVAWeights.ChargedPidMVATrainingMode``]): enum identifier
                           of the classification (binary PID) training mode.
                           See `modularAnalysis.applyChargedPidMVA` docs for available options.
        path (basf2.Path): modules are added to this path.
