[ Top ] [ Modules ]

NAME

module twoBodyStatistics

PURPOSE

This module contains routines for collecting 2-body statistics, e.g. sqrt(s) distributions and collision rates.

twoBodyStatistics/flag_sqrts [ Global module-variables ]

[ Top ] [ twoBodyStatistics ] [ Global module-variables ]

PURPOSE

If .true., then the calculation and output of the sqrts distributions from subroutine sqrts_distribution will be done

SOURCE

  logical, save :: flag_sqrts = .false.

twoBodyStatistics/flag_rate [ Global module-variables ]

[ Top ] [ twoBodyStatistics ] [ Global module-variables ]

PURPOSE

If .true., then the calculation and output of the collision rates from subroutine rate will be done

SOURCE

  logical, save :: flag_rate = .false.

twoBodyStatistics/flag_varirate [ Global module-variables ]

[ Top ] [ twoBodyStatistics ] [ Global module-variables ]

PURPOSE

If .true., then the calculation and output of the collision rates from subroutine varirate will be done

SOURCE

  logical, save :: flag_varirate = .false.

twoBodyStatistics/varirate_chargeZero [ Global module-variables ]

[ Top ] [ twoBodyStatistics ] [ Global module-variables ]

PURPOSE

If .true., then all charge states are combined together

SOURCE

  logical, save :: varirate_chargeZero = .true.

twoBodyStatistics/varirate_filterPhi [ Global module-variables ]

[ Top ] [ twoBodyStatistics ] [ Global module-variables ]

PURPOSE

If .true., then only channels involving a phi meson are reported

SOURCE

  logical, save :: varirate_filterPhi = .false.

twoBodyStatistics/varirate_size [ Global module-variables ]

[ Top ] [ twoBodyStatistics ] [ Global module-variables ]

PURPOSE

size of array to hold all rates

SOURCE

  integer, save :: varirate_size = 100

twoBodyStatistics/varirate_format [ Global module-variables ]

[ Top ] [ twoBodyStatistics ] [ Global module-variables ]

PURPOSE

indicate the format to produce the output.

It is binary coded:

  • 1 : use human readable output
  • 2 : use machine readable output (csv format)

So valid values are 1,2,3.

SOURCE

  integer, save :: varirate_format = 1

twoBodyStatistics/sqrts_mode [ Global module-variables ]

[ Top ] [ twoBodyStatistics ] [ Global module-variables ]

PURPOSE

This flag determines the way how sqrt(s) is calculated (if flag_sqrts = .true.):

  • 1 = use vacuum sqrt(s)
  • 2 = use in-medium, i.e. full sqrts

SOURCE

  integer, save ::  sqrts_mode = 1

twoBodyStatistics/init [ Subroutines ]

[ Top ] [ twoBodyStatistics ] [ Subroutines ]

NAME

subroutine init

PURPOSE

Reads in namelist "ColStat"

INPUTS

  • (none)

OUTPUT

  • Initializes global module variables

twoBodyStatistics/ColStat [ Namelists ]

[ Top ] [ twoBodyStatistics ] [ Namelists ]

NAME

NAMELIST ColStat

PURPOSE

Namelist which includes the input switches:

twoBodyStatistics/sqrts_distribution [ Subroutines ]

[ Top ] [ twoBodyStatistics ] [ Subroutines ]

NAME

subroutine sqrts_distribution(pair, itype, flag)

PURPOSE

Computes the distribution of colliding pairs of particles over sqrt(s).

INPUTS

  • type(particle), dimension(1:2), intent(in) :: pair -- incoming pair of particles
  • integer, intent(in) :: itype
  • logical, optional, intent(in) :: flag -- .true. do output

Possible values for itype:

  • 1 -- separate collision,
  • 2 -- collision in presence of a particle nearby before sqrt(s) correction,
  • 3 -- collision in presence of a particle nearby after sqrt(s) correction,
  • 4 -- elastic binary collisions
  • 5 -- inelastic binary collisions

OUTPUT

"dNdsqrts_Bm.dat" and "dNdsqrts_mm.dat".

twoBodyStatistics/dNdsqrts_BB.dat [ Output files ]

[ Top ] [ twoBodyStatistics ] [ Output files ]

NAME

file dNdsqrts_BB.dat

PURPOSE

Contains the sqrt(s) distribution of baryon-baryon collisions. Enabled by flag_sqrts.

twoBodyStatistics/dNdsqrts_Bm.dat [ Output files ]

[ Top ] [ twoBodyStatistics ] [ Output files ]

NAME

file dNdsqrts_Bm.dat

PURPOSE

Contains the sqrt(s) distribution of baryon-meson collisions. Enabled by flag_sqrts.

twoBodyStatistics/dNdsqrts_mm.dat [ Output files ]

[ Top ] [ twoBodyStatistics ] [ Output files ]

NAME

file dNdsqrts_mm.dat

PURPOSE

Contains the sqrt(s) distribution of meson-meson collisions. Enabled by flag_sqrts.

twoBodyStatistics/rate [ Subroutines ]

[ Top ] [ twoBodyStatistics ] [ Subroutines ]

NAME

subroutine rate(partIn,partOut,time,flag)

PURPOSE

Computes the collision rates for the different types of collisions.

INPUTS

  • type(particle), dimension(:) :: partIn -- incoming particles
  • type(particle), dimension(:) :: partOut -- outgoing particles
  • real, intent(in) :: time -- current time step
  • logical, optional, intent(in) :: flag -- .true. do output of the accumulated collision numbers

OUTPUT

  • file "rate.dat"

twoBodyStatistics/filterPhi [ Subroutines ]

[ Top ] [ twoBodyStatistics ] [ Subroutines ]

NAME

logical function filterPhi()

PURPOSE

apply filter on precence of phi meson

twoBodyStatistics/varirate [ Subroutines ]

[ Top ] [ twoBodyStatistics ] [ Subroutines ]

NAME

subroutine varirate(partIn,partOut,time)

PURPOSE

Computes the collision rates for alltypes of collisions.

Here the list of input and output channels are generated on the fly, thus this routine calculates the "variate-rate", or short: "varirate".

INPUTS

  • type(particle), intent(in), dimension(:) :: partIn -- incoming particles
  • type(particle), intent(in), dimension(:) :: partOut -- outgoing particles
  • real, intent(in) :: time -- current time step

OUTPUT

  • file "VariRate.particles.dat", "VariRate.rates.dat"
