Workshop on The Pion Form Factor
NIKHEF, Amsterdam, The Netherlands
January 18, 2000
The pion is a prime case for calculations of hadron structure, whether
in a perturbative QCD framework or non-perturbative ones.
Recently the electromagnetic faorm factor of the pion has been studied
with state of the art techniques at the Thomas Jefferson National
Accelerator Laboratory (experiment E93-021) and the results are about
to be available.
For this reason on January 18, 2000 a one-day workshop on
The Pion Form Factor will be organized, to discuss the data situation
and especially the status of the theory of the pion form factor and how
to reliably extract it from experimental data.
The preliminary program is included below.
The workshop is supported by the Vrije Universiteit, NIKHEF, Jefferson
Laboratory and the European HaPHEEP network.
Like for the "Amsterdam Miniconferences" participants are asked to arrange
their travel and lodging themselves (a list of hotels as well as instructions how to reach NIKHEF can be found on the
NIKHEF web page), but in return there will be no conference fee.
Persons interested to participate are asked to contact the secretary
Betsy Eimers by e-mail (betsy@nat.vu.nl).
