NAME

module omegaNucleon

PURPOSE

Includes the cross sections for omega-nucleon scattering in the resonance regime.


omegaNucleon/omegaNuc [ Subroutines ]

[ Top ] [ omegaNucleon ] [ Subroutines ]

NAME

subroutine omegaNuc(srts,teilchenIN,mediumATcollision,momentumLRF, teilchenOUT,sigmaTot,sigmaElast,useHiEnergy,HiEnergySchwelle,plotFlag, sigmaArr)

PURPOSE

Evaluates omega Nucleon -> anything cross sections and returns also a "preevent"

INPUTS

  • real :: srts --- sqrt(s) in the process
  • type(particle),dimension(1:2) :: teilchenIn --- colliding particles
  • type(medium) :: mediumATcollision --- Medium informations at the position of the collision
  • real, dimension(0:3) :: momentumLRF --- Total Momentum in LRF

High energy matching:

Debugging:

  • logical,optional :: plotFlag --- Switch on plotting of the Xsections

RESULT

  • real :: sigmaTot --- total Xsection
  • real :: 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) :: teilchenOut --- particles
  • real, dimension(6), optional :: sigmaArr -- partial cross sections

The cross sections are based upon a parametrization by Golubeva. See routine golub_omega in parametrizationBarMes.

NOTES

Possible final states are :

NAME

subroutine makeOutput

PURPOSE

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

  • 'omegaN_sigTotElast.dat' : sigmaTot, sigmaElast
  • 'omegaN_resProd.dat' : Baryon production (Resonances with ID's 1:40)
  • 'omegaN_nonStrange_nuk.dat' : non-strange meson with nucleon in final state
  • 'omegaN_strangeProd.dat' : Kaon and hyperon in final state
