NAME
function NievesHadronTensor_1pi(process_ID,q,p_in, position, charge_in, p_out,
charge_out, pion_charge_out, matrix) result(success)
PURPOSE
This function returns the hadronic tensor for 1-pion production (that is: lepton A --> lepton nucleon pion A-1) by a current type defined by "process" (e.g. CC, NC, em).
INPUTS
- integer,intent(in) :: process -- type of the process (EM, CC, NC)
- real, dimension(0:3), intent(in) :: q -- momentum transferred
- real, dimension(0:3), intent(in) :: p_in -- 4-momentum of incoming nucleon
- real, dimension(1:3), intent(in) :: position -- position --- is used for in-medium propagator
- real,intent(in) :: charge_in -- charge of incoming nucleon
- real, dimension(0:3),intent(in) :: p_out -- 4-momentum of outgoing nucleon
- real,intent(in) :: charge_out -- charge of outgoing nucleon
- real,intent(in) :: pion_charge_out -- charge of outgoing pion
OUTPUT
- complex, dimension(0:3,0:3) :: matrix -- H^mu nu
- logical, intent(out) :: success -- true if there is a coupling strength to the process;
- false if there is no coupling, therefore H^mu nu=0
NOTES
- We use the Peskin notation where the spin sum(u(p) ubar(p))=slashed(p)+m !!
