The events are produced assuming 100% polarization for the initial state electron and positron; different files for the same final state correspond to different polarization sign combinations. The variable IDRUPLH indexes the different final states and polarizations. Assume, for example, that a process has IDRUPLH=14995 . The stdhep file is ftp://ftp-lcd.slac.stanford.edu/ilc2/whizdata/ILC500/w14995_01.stdhep and the information about the generation of this file can be found in the directory ftp://ftp-lcd.slac.stanford.edu/ilc2/whizdata/ILC500/doc/run_output/w14995/run_01/ .

The WHIZARD Monte Carlo version 1.40 is used for parton generation . For processes with (for all processes except SUSY processes. WHIZARD version 1.51 is used for SUSY processes. For processes with (without) an on-shell Higgs boson in the final state the Higgs mass is assumed to be 120 GeV (2000 GeV).

Electron/Positron Beam Properties: Beamstrahlung and LINAC Energy Spread
...
The first line indicates that a user-supplied function is used to simulate the beams. A copy of this function can
be found in ftp://ftp-lcd.slac.stanford.edu/ilc3/ilcwhizdata/whizard/ILC500v1r4p0/StandardModelwhizard-v1r4p0/whizard-src/user.f90The absolute value of USER_spectrum_mode determines which energy spectrum is used, with the sign +/- indicating
electron/positron beam, respectively. For the 500 GeV SM data sample this absolute value is always 2, and corresponds
to the Guinea-Pig data contained in the directory ftp://ftp-lcd.slac for the WHIZARD 1.40 version and in ftp://ftp-lcd.slac.stanford.edu/ilcilc3/ILC500whizdata/StandardModelwhizard/guineawhizard-pig/ilc_0500_may05_run05_seed06/
This spectrum represents the default ILC design for Ecm=500 GeV circa August 2005, and includes both incoming LINAC
energy spread and beamstrahlung.
Final State Parton Showering and Fragmentation
PYTHIA 6.205 is used for final state QED/QCD parton showering and for the fragmentation of quarks and gluons. Parton showering is performed for all final state fermions with the exception of electrons. Final state QED showering of electrons is turned off because the PYTHIA final state showering code indiscriminately uses the invariant mass of final state fermion-antifermion pairs for the maximum virtuality scale. Default parameters are used for parton showering and fragmentation.
The interface to PYTHIA is contained in 1.95/whizard-src/user.f90 for the WHIZARD 1.95 version. This function refers to links with the names ..._linker_000... which can be found in
ftp://ftp-lcd.slac.stanford.edu/ilcilc3/ILC500whizdata/StandardModelwhizard/whizardguinea-srcpig/user.f90 . The source code for referenced subroutines can be found in ftp://ftp-lcd.slac.stanford.edu/ilc/ILC500/StandardModel/a6f/include .Color flow information was not available in WHIZARD 1.40, and so kinematic and parton id information is used to identify color singlet systems (see energy_spread.
The absolute value of USER_spectrum_mode determines which energy spectrum is used, with the sign +/- indicating
electron/positron beam, respectively. For the Ecm = 500 GeV SM data sample this absolute value is always 2, and corresponds
to the Guinea-Pig data contained in the directory ftp://ftp-lcd.slac.stanford.edu/ilc/ILC500/StandardModel/a6fguinea-pig/include/ilc_fragment_call.f90 and ftp://ftp-lcd.slac.stanford.edu/ilc/ILC500/StandardModel/a6f/include/calc_a1sq_a2sq.f90
).
Kinematic Cuts
Kinematic cuts are applied to massless particle configurations where some cutoff is required to avoid an infinite cross section. In the WHIZARD event generation stage we set the masses of all first and second generation fermions to zero, so that photons, gluons, electrons, muons and u,d,s,c quarks are all subject to kinematic cuts. The cuts are given by the WHIZARD input parameters default_jet_cut, default_mass_cut and default_q_cut . We use the WHIZARD default value
default_jet_cut=10 GeV for the minimum invariant mass of a pair of colored particles. We use default_mass_cut=4 GeV for the minimum invariant mass of a pair of colorless particles, and we use default_q_cut=4 GeV for the minimum sqrt(-Q**2) for
massless t-channel processes.
The massless assumption for the first and second fermion generations can produce some odd results given the kinematic cut values we have chosen. For example, the cross section for gamma gamma -> tau tau is significantly larger than the cross section for gamma gamma -> mu mu since the cut value of 4 GeV for default_mass_cut and default_q_cut is much larger than the tau mass.
Also the cross section for gamma gamma -> qq is suppressed relative to the corresponding cross section for lepton pair
production because the cut value of 10 GeV for default_jet_cut is larger than the cut value of 4 GeV for default_mass_cut .
Derived stdhep files.
There are over 3500 files in ftp://ftp-lcd.slac.stanford.edu/ilc2/whizdata/ILC500/, each produced with 100% electron and positron polarization. To use these
stdhep files in practice one must read the correct number of events from a subset of these files, or read a derived stdhep file. A derived stdhep file is built from the files
in ftp://ftp-lcd.slac.stanford.edu/ilc2/whizdata/ILC500/ and corresponds to a particular subset of final states with a particular initial state electron and positron polarization
combination (such as -80% electron and +30% positron).
Event Weight
Due to the presence of some high cross section processes, the events in a derived stdhep file are not completely unweighted.
The event weight must therefore always be considered when analyzing events.
This weight is stored in the variable EVENTWEIGHTLH in the stdhep common block HEPEV4.
Process Identification
For each event in a derived stdhep file the variable IDRUPLH from the common block HEPEV4 is used to identify the process. (See the
description of the IDRUPLH variable in the introduction above.)

This spectrum represents the default ILC design for Ecm=500 GeV circa August 2005, and includes both incoming LINAC
energy spread and beamstrahlung.
For the Ecm = 250 GeV SM data sample the absolute value of USER_spectrum_mode is 4 for the LOI samples with do_isr = T, and USER_spectrum_mode is 5 for the post-LOI samples with do_isr = F. The Guinea-Pig data for USER_spectrum_mode=5 is in ftp://ftp-lcd.slac.stanford.edu/ilc3/ILC250/LOI_backgrounds/guineapig/postLOI/guineapig/lumionly/raw . USER_spectrum_mode=6 corresponds to SB2009_350_nTF_extbunches. USER_spectrum_mode=7 corresponds to SB2009_500_nTF_extbunches.

PYTHIA 6.205 is used for final state QED/QCD parton showering and for the fragmentation of quarks and gluons. Parton showering is performed for all final state fermions with the exception of electrons. Final state QED showering of electrons is normally turned off because the PYTHIA final state showering code indiscriminately uses the invariant mass of final state fermion-antifermion pairs for the maximum virtuality scale; however, PYTHIA final state QED showering of electrons was turned on for all Ecm = 250 GeV processes so that its effects could be studied in e+e- --> e+e-H. Otherwise default parameters are used for parton showering and fragmentation.

Mixed stdhep files.
There are over 3500 files in ftp://ftp-lcd.slac.stanford.edu/ilc2/whizdata/ILC500/, each produced with 100% electron and positron polarization. To use these
stdhep files in practice one must read the correct number of events from a subset of these files, or read a mixed stdhep file. A mixed stdhep file is built from the files
in ftp://ftp-lcd.slac.stanford.edu/ilc2/whizdata/ILC500/ and corresponds to a particular subset of final states with a particular initial state electron and positron polarization
combination (such as -80% electron and +30% positron).
Event Weight
Due to the presence of some high cross section processes, the events in a mixed stdhep file are not completely unweighted.
The event weight must therefore always be considered when analyzing events.
This weight is stored in the variable EVENTWEIGHTLH in the stdhep common block HEPEV4.
Process Identification
For each event in a mixed stdhep file the variable IDRUPLH from the common block HEPEV4 is used to identify the process. (See the
description of the IDRUPLH variable in the introduction above.)

The lumi values in this table refer to the event weight normalization, and may not correspond in some instances to the ratio of the number of events to the cross section. Each Mixed Stdhep
File directory contains files inv_ab_stdhep_files_XXX_ecmEEE_80L_30R and inv_ab_stdhep_files_XXX_ecmEEE_80R_30L which describe the raw stdhep files used to build the mixed files (for example ftp://ftp-lcd.slac.stanford.edu/ilc/ILC250/Large_Stdhep_SM/inv_ab_stdhep_files_Large_Stdhep_SM_ecm250_80L_30R).
The fields in the ..._inv_ab_stdhep_files are:
filename (at SLAC) |
| Begin event |
| End event |
| Event weight |
| process_id |
| 1st initial particle polarization if particle is e- or e+; beams/brems flag if photon |
| 2nd initial particle polarization if particle is e- or e+; beams/brems flag if photon |

The "index" link in the "Raw Stdhep Files" column takes you to the list of processes in the mixed stdhep file. The five columns in this list are: process_id, initial_state,
the variable IDRUPLH, an internal sequence number (1 - 4) and a bit indicating whether or not events were produced for this particular initial state polarization sign combination (0 = events generated, 1= events not generated). The internal sequence number denotes the initial state electron or positron helicity and/or the type of initial state photon (EPA or bremsstrahlung):
