PURPOSE
- Provides propagators, i.e. two-point functions
propagators/propagator_3_2_vac [ Functions ]
[ Top ] [ propagators ] [ Functions ]
NAME
function propagator_3_2_vac(resID,p_res) result(propagator)
PURPOSE
- Provides a spin=3/2 propagator G^{mu,nu} of a resonance in vacuum. Note that G^{mu nu} is a 4x4 matrix.
INPUTS
- real, dimension(0:3),intent(in) :: p_res ! resonance 4-momentum
- integer :: resID ! ID of the resonance
OUTPUT
complex,dimension(0:3,0:3,0:3,0:3), intent(out) ::propagator First two indices =mu,nu, i.e. (G^{mu,nu} )_ij=propagator(mu,nu,i,j)
