polarization (xx/xx/19)
 
4
      OM: Allow syntax for (fully) polarized particles:
 
5
           ex: p p > w+{L} j, e+{L} e-{R} > mu+ mu- Z{T}
 
6
               p p > w+{T} w-{L} j j, w+ > e+ ve, w- > j j
 
7
               p p > w+{T} j [QCD]   (beta)
 
8
          polarization@NLO does not work for QCD charged particle and is still beta
 
9
               as it can lead to weird crash
 
10
      OM: distinguish in the code if zero contribution are related to no point passing cuts or if
 
11
          they are related to vanishing matrix-element. In the later case, allow for a lower threshold.
 
12
          (This allow to fasten the computation of such zero contribution)
