Detailed Description

This processor is calculating the invariant mass for the 2 specified objects.

Objects could be electrons (TMBEMCluster), muon (TMBMuon), jet (TMBJet) or TMBLorentzVector. For electron and muon you also can specify what kind of pt, eta and phi you want to use. There is a choice between the "best" quality (default) or the "track" one.

The calculated mass saved as name()+"ResMass" variable (double) to the Event. The pointer to the first objects also saved to the Events as name()+":EM1" or name()+":Muon1" or name()+":Jet1" or name()+":LorentzVector1" and with number 2 instead of 1 for the second object. You can test the existance of each object using cafe::Event::get() methode:
if(event.get("name",electron)) do something

You can choose reconstruction method specifying the option .target_mass

choose pair with highest invariant mass if "target_mass" is negative (default)
choose pair mass closest to mass specified with "target_mass" option.

You also can apply selection on the reconstructed mass.

If options "lower_mass_bound" and "upper_mass_bound" are non negative, only events with lower_mass_bound <= mass <= upper_mass_bound will pass the selection.
If option "Charge" has value "opposite" only pairs with opposite sign will be chosen. If value is "samesign" only objects with the same charge sign will be chosen. The default option is "noselection".

Selector also can build the invariant mass histogram if "hist_bins" value greater than 0.

Optional parameters:

.Branch1: name of the branch with the first object [default: "Muon"]
.Object1_type: first object type. Could be muon, electron, jet or TMBLorentzVector [default: "TMBLorentzVector"]

.Branch2: name of the branch with the second object. Can be the same as the first one. In that case all possible combination will be calculated and all objects with the same ROOT Unique ID will be rejected. [default: Branch1]
.Object2_type: the object type for the second object [default: "TMBLorentzVector"]

.Object1_method: what kind of pt, eta and phi should be used. Available method "best" for all objects type (pt, eta, phi from the TMBLorentzVector will be used) and "track" for electron an muon (pt, eta and phi will from the track matched to the object will be used) [default: "best"]
.Object2_method: the same as Object1_method, but for the second object [default: "best"]

.target_mass: reference invariant mass [default: -1.0 - the highest invariant mass will be chosen]
.low_mass_bound: if invariant mass lower than this value, event will be rejected [default: -1.0 no selection]
.upper_mass_bound: if invariant mass higher than this value, event will be rejected [default: -1.0 no selection]

.UseEOPTrackMatchElectron: Use EOP track matched electrons [default: false]

.Charge: accept only objects pair with the specified charges. Available options "opposite", "samesign", "noselection" [default: "noselection"]

.hist_bins: if this value greater than 0, the invariant mass histogram with name "masshist_"+name() will be build [default: 0]
.hist_lower: histogram lower limit [default: 0.0]
.hist_upper: histogram upper limit [default: 120.0]
