Dear Michael,
Many thanks for your detailed clarification.
It might be that I am wrongly understood. Certainly, Juergen did a lot
for the experiment and he is/will be perfect coordinator of the both
lumi detectors.I agree that providing reliable luminosity numbers is as
important as correctly done tracking, well organized MC simulation, etc.
PNPI group is/will be involved in this lumi analysis being responsible
for MWPC calibration, digitization, geometry,..But we consider this
obligation as
only a part of our commitment in the OLYMPUS analysis. We are planning
to thoroughly study systematics, and based on that extract the physical
effect we all aim at. Our students are working on internal
bremsstrahlung and vacuum loops, and pion production background.They
also need PhD theses.
Unfortunately, we had to measure at one toroid polarity, and thus we
have measured double ratio instead of 4-fold ratio as was conceived in
the proposal. This make the analysis much more complicate and much more
dependent on MC. In such a situation I find it absolutely crucial to
compare the result to be obtained at MIT with that obtained by one (at
least) other group, which might be, e.g., a group of unified efforts at
DESY.
Both groups should stay at the same ground, and so must be coordinated
by one person equally involved in the two analyses.This is my vision of
the situation.
With best regards StanB
