Charge Symmetry Breaking and Other
Isospin Violations
An international workshop will be held June 13-17, 2005 in
Trento, Italy
at the European Center for Theoretical Studies in Nuclear Physics and
Related Areas.
QCD is invariant under the
interchange of up and down quarks. This charge symmetry is broken
only by electromagnetic effects and the up and down quark masses.
These masses are poorly known fundamental parameters, and learning the
phenomenalogical influence of their difference is an important way to
improve understanding of the standard model. The impetus for this
workshop is provided by two recent charge symmetry breaking (CSB)
experiments involving the production of neutral pions. The
Cooler CSB experiment at Indiana deteced the CSB reaction d+d to
alpha+pi0 while a CSB forward-backward asymmetry was observed at TRIUMF
in the reaction n+p to d+pi0. Furthermore there are
exciting possibilities for new experiments at COSY-Juelich and
elsewhere and new opportunities provided by theoretical advances in
effective field theory and the understanding of few body systems.
Topics will include:
- Effective field
theory and isospin violation.
- Experiments with
pions.
- Microscopic pion
production calculations.
- Charge Symmetry
Breaking and Isospin violation in other systems.
- Applications of
Charge Symmetry Breaking.
- Future Experiments.
