amplitudes_2Pi/ampli [ Functions ]

[ Top ] [ amplitudes_2Pi ] [ Functions ]

NAME

function ampli(r,q,p1,p2,p4,p5,o,betaToLRF,mediumAtPosition) result(t)

PURPOSE

Calculates the 2pi photoproduction amplitude taken from Nacher et. al. NPA 695 (2001) 295. t is given in the CM frame, only transverse components are calculated.
