/dimi [ Modules ]
NAME
module dimi
PURPOSE
Includes the N N <-> Delta N cross sections according to the OPE model by Dmitriev et al. See:
- Diploma Thesis Effenberger, chapter 3.3.1
- Dmitriev/Sushkov/Gaarde, Nucl. Phys. A 459 (1986) 503-524
dimi/massNN_NDelta [ Functions ]
[ Top ] [ dimi ] [ Functions ]
NAME
function massNN_NDelta (srts) result (massDelta)
PURPOSE
Evaluates masses in N N -> N Delta process using dimidm. This is done by a Monte-Carlo process utilizing dsigma/dm.
dimi/dimiSigma [ Functions ]
[ Top ] [ dimi ] [ Functions ]
NAME
function dimiSigma (srts, massDelta) result (sigma)
PURPOSE
Returns the cross section for Delta++ n -> pp scattering.
dimi/dimiIntegrated [ Functions ]
[ Top ] [ dimi ] [ Functions ]
NAME
function dimiIntegrated (srts) result (dsdm_Integrated)
PURPOSE
Returns the cross section for p p -> Delta++ n scattering, integrated over the Delta mass.
dimi/setMaxSqrts [ Subroutines ]
[ Top ] [ dimi ] [ Subroutines ]
NAME
subroutine setMaxSqrts(srtsMax)
PURPOSE
set the upper bound of the tabulation
dimi/dimidm [ Subroutines ]
[ Top ] [ dimi ] [ Subroutines ]
NAME
subroutine dimidm (dsdm, dsdmIntegrated, sigma, srts, mdel)
PURPOSE
this subroutine calculates the cross sections for p p <-> Delta++ n Stores cross sections at first call to a field and then it only returns those field values.
INPUTS
OUTPUT
- real :: sigma -- total cross section (for reaction with incoming delta)
- real :: dsdm -- mass differential cross section as function of mdel and srts (for reaction with outgoing delta)
- real :: dsdm_Integrated -- mass differential cross section integrated over mass as function of srts (for reaction with outgoing delta)
dimi/mnnnd2 [ Functions ]
[ Top ] [ dimi ] [ Functions ]
NAME
real function mnnnd2(t,u,mdel)
PURPOSE
return Matrix element squared and averaged over initial and summed over final spins for p_1 p_2 -> n_3 delta_4^++ (within Dmitriev and Sushkov model with effective nucleon and delta masses).
