[ Top ] [ Modules ]

NAME

module kaonSigma_resonance

PURPOSE

Includes the cross sections for kaon-sigma scattering in the resonance regime

Public routines:

NOTES

Resonances are included into the model of Huang et al for calculating the cross sections. After this, the treatment is done as for 2 -> 2 reactions.


kaonSigma_resonance/kaonSigma [ Subroutines ]

[ Top ] [ kaonSigma_resonance ] [ Subroutines ]

NAME

subroutine kaonSigma (srts,teilchenIN,teilchenOUT,sigmaTot,sigmaElast,plotFlag)

PURPOSE

Evaluates kaon sigma -> anything cross sections and returns also a "preevent"

INPUTS

  • real, intent(in) :: srts ! sqrt(s) in the process
  • type(particle),dimension(1:2), intent(in) :: teilchenIn ! colliding particles

Debugging:

  • logical, intent(in),optional :: plotFlag ! Switch on plotting of the Xsections

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 :


kaonSigma/evaluateXsections [ Subroutines ]

[ Top ] [ kaonSigma ] [ Subroutines ]

NAME

subroutine evaluateXsections

PURPOSE

Evaluates kaon sigma -> anything cross sections

NOTES

There are no resonance contributions to kaon Sigma scattering. The contributions are given by Huang parametrizations of pi N(Delta) -> Kaon Sigma using detailed balance relations.

kaonSigma/makeOutput [ Subroutines ]

[ Top ] [ kaonSigma ] [ Subroutines ]

NAME

subroutine makeOutput

PURPOSE

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

  • 'kaonSigma_sigTotElast.dat' : sigmaTot, sigmaElast
  • 'kaonSigma_nonStrange.dat' : non-strange meson in final state
