(=POlarization at Work in Energetic
General remarks about our group
The Institute for
Particle Physics Phenomenology (IPPP) at the University of Durham (UK)
hosted our first meeting:
Future plans and minutes from the first meeting
propotype for polarized positrons under work:
helical undulator at Daresbury, ASTeC, time schedule:
about 3 years
undulator based positron beams at SLAC: about
polarimetry problem for polarized positrons at prototype;
under engaged discussion
between our polarimetry experts, first solutions
proposed (contact -> Peter Schueler)
close contact between SLAC and DESY needed!
experience from SLC and new results from HERA provided!
electron polarization mandatory for LC
positron polarization needed for 'fixing' of underlying
structure of New Physics and Blondel Scheme
transversal polarization interesting for test of
gauge couplings and for probably CP violating
study of polarized fragmentation functions
for b-quarks at a LC
'balance' for pros and cons: David proposed the
preparation of a `shooting'
longitudinal electron and positron polarization
transversal polarization still missing
Further proposals: for all topics we should have one person 'in charge',
who keeps the group
informed about the news.
List of outstanding problems
Problems of machine designs; In charge: John?
List with problems needed!
Status of helical undulator; In charge: Jim?
Status of prototype at 50 GeV; In charge: John?Rainer?
Problems of polarimetry: solution proposed; In charge:
Theoret. uncertainty for GigaZ still higher than
the possible experimental accuracy
For all SUSY processes: critical collection of pro's and
More and detailed studies for transversal polarization
In charge: Michael
for higher orders?
Achim for exp. studies?
Gudi for SUSY.
In principle: good state for Monte Carlo's
Implementation of transversal polarization
seems to be no problem!
In charge: Peter
