HiLeptonAnalysis/DoHiLeptonAnalysis [ Subroutines ]

[ Top ] [ HiLeptonAnalysis ] [ Subroutines ]

subroutine DoHiLeptonAnalysis(realPart,pertPart,MassNum,finalFlag,beforeRUN)

PURPOSE

This is the routine, which does the actual analysis for HiLepton calculations

INPUTS

NOTES

If this routine is called with beforeRUN=.true., then production and formation times of the particles produced in the first event are reported. Otherwise, after all timesteps, particle spectra etc are stored.

HiLeptonAnalysis/BinCutsJLAB5_R [ Subroutines ]

[ Top ] [ HiLeptonAnalysis ] [ Subroutines ]

NAME

subroutine BinCutsJLAB5_R(nu,Q2,zH, iNu,iQ2,iZH)

PURPOSE

select the histogramm to bin the values of R

HiLeptonAnalysis/BinCutsJLAB5_pT2 [ Subroutines ]

[ Top ] [ HiLeptonAnalysis ] [ Subroutines ]

NAME

subroutine BinCutsJLAB5_pT2(nu,Q2,zH, iNu,iQ2,iZH)

HiLeptonAnalysis/checkCuts [ Subroutines ]

[ Top ] [ HiLeptonAnalysis ] [ Subroutines ]

NAME

subroutine checkCuts(Part,nu,Q2,Ebeam,phi_Lepton,acceptFlag,weight)

PURPOSE

This routine applies the experimental cuts and returns some weight, which indicate the probability, that the parton is detected.

As a side effect, it calculates the transverse momentum of the particle in respect to the photon direction.

INPUTS

  • type(particle) :: Part -- particle to consider
  • real :: nu -- nu value of Event
  • real :: Q2 -- Q**2 value of Event
  • real :: Ebeam -- Energy of the Lepton Beam
  • real :: phi_Lepton -- Angle of scattered Lepton

OUTPUT

  • logical :: acceptFlag -- true, if particle is detected at all
  • real :: weight -- weight of acceptance
  • real, OPTIONAL :: pT2 -- transverse momentum according lepton beam

NOTES

phi_Lepton indicates the azimuthal angle of the scattered lepton around the axis, which is determined by the momentum of the incoming lepton. This is normally not the z-axis. (see below)

A particle can be detected, but, e.g. due to rotational systematics around the lepton beam axis, only in 50% of all cases. If the details of the detector are not important, you can then give the particle the acceptance weight 0.5.

Be aware: The events are normally in a system, where the PHOTON determines the z-axis.

HiLeptonAnalysis/labrotate [ Subroutines ]

[ Top ] [ HiLeptonAnalysis ] [ Subroutines ]

NAME

subroutine labrotate(alpha,phi_Lepton,p,theta,phi,pT2)

PURPOSE

Because AccWeight is an rotation-averaged value, we have now to choose the "phi" angle.

INPUTS

  • alpha : angle to rotate around y-axis
  • phi_Lepton : angle to rotate arund z-axis
  • p : vector to rotate

OUTPUT

  • theta : angle
  • phi : angle
  • pT2 : transverse momentum (squared) acording lepton axis

NOTES

First the vector is rotated around the y-axis by the angle alpha (i.e. the angle between incoming lepton and photon). Secondly, this vector is rotated around the z-axis by the angle phi_Lepton.
