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 in Amsterdam 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 format will be plenary talks (mostly invited, but there is room for one or two contributed talks) with ample time for discussion.

The topics to be discussed include:

data situation (including recent 1H(e,e'pi+) and 2H(e,e'pi+)
and 2H(e,e'pi-) results)
perturbative QCD calculations of the pion form factor
QCD and other sum rule calculations
soft calculations
description of pion production on the proton and neutron
with Born or Regge models

The workshop is supported by the Vrije Universiteit, NIKHEF, Jefferson Laboratory and the European HAPHEEP network.

In order to emphasize the discussions and the workshop character the attendance is limited to about 35 people and will be by invitation only.

Like for the "Amsterdam Miniconferences" participants are asked to arrange their travel and lodging themselves (a list of hotels 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). A more detailed program including confirmed speakers will be sent to the participants soon.
