Useful Subsets of the Inclusive Lepton Datasets
(Ntuple Version)
We have generated a number of useful collections of
UC standard
ntuples which are ready for immediate analysis by PAW, ROOT, or
your own favorite histogramming package that understands HBOOK4
column-wise ntuples.
Starting with our Run 1B
inclusive electron
and inclusive muon PAD files, we have created a set of ntuples
corresponding to all inclusive electrons (ICEFLT) and another set
corresponding to all inclusive muons (CMUFLT). These ntuples are
organized by Stream A DST tape name, one for each tape
(e.g., tape CCK000 gave birth to the ntuple ICEFLT_CCK000.NT).
Using simple FORTRAN filters,
the combined ICEFLT/CMUFLT ntuples are skimmed and merged into useful
subsets.
Ntuple file names and the FORTRAN filter source code are
included in the links
below.
-
Two CEM clusters (ELEELE)
Two central electron/photon candidates with
transverse energy greater than 20 GeV
and calorimeter isolation less than 0.15.
-
Muon and a CEM cluster (CMUELE)
One central electron/photon candidate with
transverse energy greater than 20 GeV
and calorimeter isolation less than 0.15, and
one muon candidate with
transverse momentum greater than 20 GeV
and calorimeter isolation less than 0.15.
-
W electrons (WENU)
One tight central electron with transverse energy greater than
20 GeV and missing transverse energy greater than 20 GeV.
-
W muons (WMUNU)
One tight muon with transverse momentum greater than
20 GeV and missing transverse energy greater than 20 GeV.
-
Z dielectrons (ZEE)
One tight central electron with transverse energy greater than
20 GeV and
a second central/plug/forward electron
candidate with transverse energy greater than
20/15/10 GeV.
-
Z dimuons (ZMUMU)
One tight muon with transverse momentum greater than
20 GeV and
a second muon candidate with transverse momentum greater
than 20 GeV.
-
Z dielectrons (ZEE); loose cuts
One central electron with transverse energy or
corrected transverse energy greater than
20 GeV and
a second central/plug/forward electron
candidate with transverse energy or
corrected transverse energy greater than
20/15/10 GeV.
-
Z dielectrons (ZEE); tight cuts
Two tight isolated central electrons with Et greater
than 25 GeV (estat > 9025).
-
Lepton Photon (LGAMMA)
One tight central lepton (electron or muon) and a good
photon.
These are all also on CD.
