Member Function Documentation

TComplex JenkovszkyModel::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
tin GeV^-2, t < 0

Implements Elegent::Model.

TComplex JenkovszkyModel::Prf ( double  b) const
virtual

Profile function (amplitude in b-space).

Normalisation is such that \( Amp(t) = 2 p \sqrt{s} \int db b Prf() J_0(b \sqrt{-t}) \)

Parameters
bin fm.

Implements Elegent::Model.
