Member Function Documentation

TComplex DLModel::Amp ( double  t ) const

virtual

Amplitude in t-space.

Normalisation is such that \( dsigma/dt = (\hbar c)^2 * \pi / (s p^2) * |Amp(t)|^2 \) Differential cross-section can be obtained as Constants::sig_fac * |Amp(t)|^2

Parameters

t	in GeV^-2, t < 0

Implements Elegent::Model.
