NAME

module pionP11_1440_resonance

PURPOSE

Includes the cross sections for pion-P11_1440 scattering in the resonance regime. Implemented are the following reactions:

  • pion P11_1440 -> X

Public routines:


pionP11_1440_resonance/pionNuc [ Subroutines ]

NAME

subroutine pionNuc(srts,teilchenIN,mediumATcollision,momentumLRF,teilchenOUT,sigmaTot,sigmaElast,plotFlag)

PURPOSE

Evaluates pion P11_1440 -> anything cross sections and returns also a "preevent"

RESULT

  • real, intent(out) :: sigmaTot ! total Xsection
  • real, intent(out) :: sigmaElast ! elastic Xsection

This routine does a Monte-Carlo-decision according to the partial cross sections to decide on a final state with maximal 3 final state particles. These are returned in the vector teilchenOut. The kinematics of these teilchen is only fixed in the case of a single produced resonance. Otherwise the kinematics still need to be established. The result is:

  • type(preEvent),dimension(1:3), intent(out) :: teilchenOut ! colliding particles

NOTES

Possible final states are :

NAME

subroutine makeOutput

PURPOSE

Writes all cross sections to file as function of srts and plab [GeV]. Filenames:

  • 'pionP11_1440_sigTotElast.dat' : sigmaTot, sigmaElast
  • 'pionP11_1440_resProd.dat' : Baryon resonance production
