NAME
module omegaNucleon
PURPOSE
Includes the cross sections for omega-nucleon scattering in the resonance regime. Public routines:
omegaNucleon/omegaNuc [ Subroutines ]
[ Top ] [ omegaNucleon ] [ Subroutines ]
NAME
subroutine omegaNuc(srts,teilchenIN,mediumATcollision,momentumLRF, teilchenOUT,sigmaTot,sigmaElast,useHiEnergy,HiEnergySchwelle,plotFlag)
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:
- logical :: useHiEnergy --- .true. if High-Energy cross sections are given by paramBarMesHE
- real :: HiEnergySchwelle --- threshold sqrt(s) for paramBarMesHE, i.e. at which energy the cross sections of paramBarMesHE are used
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
The cross sections are based upon a parametrization by Golubeva. See routine golub_omega in parametrizationBarMes.
