QCD of bound states: Approach
Increase precision
measure static properties of well known states
Increase the database of decays
search for unusual decay modes to gain information
Excite additional modes
search for gluonic and radial excitations of hadrons
search for gluonic excitation of the strong vacuum
Put the hadrons to the limits
put the hadrons in vacuum with different baryon density

LoI Analysis 3: μ+μ- from J/ψ produced in p63Cu
Signal
J/ψ
Calculations from A. Sibirtsev
at √s=4.05 GeV/c2
Background
UrQMD events
Muons come from the
decay of light hadrons
To be done
more statistics fro the
UrQMD background,
so that the background
shape under the J/ψ is
clearly visible

PAX – Polarized Antiproton Experiment
Motivation
The transversity distribution is the last
leading-twist missing piece of the QCD
description of the partonic structure of
the nucleon
The transversity distribution is directly
accessible uniquely via the double
transverse spin asymmetry ATT in the
Drell-Yan production of lepton pairs ....
... and/or via J/ψ production, which
might be two orders of magnitude
higher
Main problems:
physics favors large s (>50 GeV2)
needs large polarization
of beam and target
beam polarization technique unverified
31

ASSIA –
A Study of Spin dependent
Interactions with Antiprotons
Investigate also Drell-Yan
Proposed with 40 GeV/c beam
accelerated by SIS300
Target
NH3 10g/cm2
Luminosity
up to 1.5x1031cm-2s-1
as single user
Detector
first part of COMPASS

Recommendations of the FAIR QCD PAC
Panda
The PAC accepts the letter and asks the proponents to go
ahead to a Technical Proposal
PAX and ASSIA
The PAC considers the spin physics of extreme interest and the
building of an antiproton polarized beam as a unique possibility
for the FAIR project,
but
does not approve the letters of intent
asking
for a more detailed study of achievable antiproton polarization
and the anticipated physics results.

K. Peters - Panda and Charmonium Prospects at FAIR
Summary and Outlook
It’s an amazing time in charm spectroscopy
many new states – but no coherent picture
Where are gluonic excited charmonia (hybrids)
spectrum, widths and decay channels
What are the new DsJ states and the X(3872)
what are their properties like width and decay channels
Interaction with nuclear matter
mass shifts, broadening and attenuation
Only high precision experiments can finally
help to solve the puzzle like Panda @ HESR @ GSI
