/pionPot [ Modules ]
NAME
module pionPot
PURPOSE
Includes several modules to determine the pion potential.
pionPot/pionPot_Main [ Subroutines ]
[ Top ] [ pionPot ] [ Subroutines ]
PURPOSE
determine scalar potential for pion, to use in mesonpotential Potential is defined as oth component of a vectorpotential in the LRF routine is called by mesonpotential. The potential should not be used above 250 MeV momentum.
pionPot/pionPot_DeltaHole [ Subroutines ]
[ Top ] [ pionPot ] [ Subroutines ]
PURPOSE
Evaluates potential for pion according to simple Delta-Hole-Model See Diploma-Thesis O.Buss,pages 18-22
INPUTS
- real :: rhop,rhon -- proton and neutron density
- real,dimension(1:3), intent(in) :: p-- !momentum of pion in GEV
- real, intent(in) :: masse -- mass of pion in GEV
RESULT
- real, intent(out) :: Vopt -- in GEV
pionPot/pionPot_Kapusta [ Subroutines ]
[ Top ] [ pionPot ] [ Subroutines ]
PURPOSE
Evaluates potential for pion according to Kapusta.
INPUTS
- real :: rho -- density in fm^-3
- real, intent(in) :: k -- absolute momentum in GeV
RESULT
- real, intent(out):: VOpt -- optical potential as oth component of vector potential in GeV
pionPot/pionPot_Smooth [ Subroutines ]
[ Top ] [ pionPot ] [ Subroutines ]
PURPOSE
Berechnet das potential des pions lineare extrapolation zwischen oset-potential um Ekin=0 und simplen DeltaHole-Potential Gueltigkeit: bis 130 MeV Ekin
INPUTS
- real :: rhop,rhon !proton and neutron density
- real, dimension(1:3),intent(in) :: momentum !in GeV
- real, intent(in) :: masse !mass of pion in GEV
RESULT
- real, intent(out) :: Vopt !in GEV
pionPot/pionPot_oset [ Subroutines ]
[ Top ] [ pionPot ] [ Subroutines ]
PURPOSE
evaluates real part of the pion selfenergy and pion decay width according to (NPA 554 pages 554 and following) Oset, Salcedo et al. All calculations are done in MEV and then converted to GEV in the end!
NOTES
This Routine calls two subroutines, which evaluate s-Wave and P-Wave of the Selfenergy. These Subroutines evaluate the full selfenergy.
