Neutral and
Charged Current Results from the e+p running period 1994- 1997
Figures of 1995:
Differential x Cross Section of CC and
NC
This devonvoluted cross section is based on e+ data taken 1994 and
1995.
In order to get comparable cross sections for CC and NC the kinematics
for both processes were derived form hadronic variables.
Differential y Cross Section of CC and
NC
This decvonvoluted cross section is based on e+ data taken 1994 and
1995.
In order to get comparable cross sections for CC and NC the kinematics
for both processes were derived form hadronic variables.
Differential q^2 Cross Section of CC
and NC
This devonvoluted cross section is based on e+ data taken 1994 and
1995.
In order to get comparable cross sections for CC and NC the kinematics
for both processes were derived form hadronic variables.
Helicity fit to ds/dy(CC)
Applying a fit of the theortical prediction of the CC-cross section
with
two free parameters a and b for the contribution of the antiquarks (a)
and the quarks (b) to the measured ds/dy cross section of CC,
one can disentangle the different states of helicity of antiquarks
and quarks in the proton.
This fit is based on the analytical program EPRC using the MRSH
parameterization.

Ratio of NC/CC cross sections as function of Q^2 (eps))
This plot is based on 1994 e+p data.
NC and CC dsigma/dQ^2 as eps or
as ps-file
This plot is based on H1 and ZEUS NC and CC e+p data.
CC dsigma/dQ^2 eps file or
ps-file
dsigma/dQ2 for charged current data from HERA (H1 and ZEUS). Cross
sections
for electron and positron induced reactions.
Isolated Leptons and missing transverse momentum:
The acceptance of lepton
events from W decay in terms of pt of the
hadrons.
