Get the mass-differential width \( d\Gamma / dm \) for a dilepton Dalitz decay, where \( m \) is the invariant mass of the lepton pair.
This differential width is used directly for the dilepton shining weights. It is calculated according to Weil:2013mya [60], eq. (30)-(36).
Also see Staudenmaier:2017vtq [55] for a description of dilepton production in SMASH.
