Charge Symmetry Breaking and Other Isospin Violations

ECT* Conference Site

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:


Note, there is a related workshop June 20-July 1, 2005 at ECT* in Trento on "Nuclear Forces and QCD: Never the Twain Shall Meet?"
