• Measured as a function of

• Direct access to quark

• Hard scale:

• Soft part can be separated
and parameterised by
generalised distribution

• Experimental problem:

Crossed channel p p  ee:
• Goals:
– To measure time-like FF from
threshold up to high s = q2 in
one experiment
(reduced systematic error)
– To compare with space-like
FFs (pQCD at large s?)
• PANDA:
– Wide kinematical range
– Large solid angle coverage
– Large statistics
 High-quality measurement
of both GE and GM
