/hadronTensor_QE [ Modules ]

[ Top ] [ Modules ]

NAME

module hadronTensor_QE

PURPOSE

  • Evaluates the hadron tensor for gamma N -> N'
  • For details see the notes about this in the PhD of Oliver Buss


hadronTensor_QE/extraTerm [ Global module-variables ]

[ Top ] [ hadronTensor_QE ] [ Global module-variables ]

SOURCE

  logical, save :: extraTerm=.true.

PURPOSE

Switch to take out the extra term which preserves charge conservation in case of a momentum dependend mass.


hadronTensor_QE/H_munu_QE [ Functions ]

[ Top ] [ hadronTensor_QE ] [ Functions ]

NAME

real function H_munu_QE(mu,nu,pin,pout,nucleonCharge)

PURPOSE

calculate the hadronic tensor for QE scattering

INPUTS

  • integer :: nu, mu -- Lorentz indices
  • real, dimension(0:3) :: pin,pout -- incoming/outgoing nucleon momentum
  • integer :: nucleonCharge -- charge of nucleon

NOTES

This routine is highly inefficient, since it recalculates many things, even if only the lorentz indizes have changed sinc the last call.
