Meetings Organized on

EFT-Related Topics

Nuclear Effective Field Theory has become quite a popular field, and we have organized several meetings on various, related issues.

We have organized two specialized workshops: Nuclear Physics with Effective Field Theory, held at Caltech in February 1998, and Nuclear Physics with Effective Field Theory: 1999, held at the INT in February 1999. Proceedings of both the first and second workshops have been published by World Scientific. They offer a good sample of basic developments in nuclear EFT.

A more general workshop on The Nuclear Interaction: Modern Developments that included also other approaches to the nuclear-force problem took place at the ECT* in the summer of 1999. (Pictures!) A second workshop with the same scope, Theories of Nuclear Forces and Few-Nucleon Systems, took place in June 2001 at the INT. (Transparencies!) These were followed by a much longer INT Program on Theories of Nuclear Forces and Nuclear Systems in the Fall 2003. (Transparencies!) The last meeting in this series was Workshop on Nuclear Forces and QCD: Never the Twain Shall Meet?, again at the ECT*, in June/July 2005. A related program on the interface with many-body methods took place in the Spring 2009, INT Program on Effective Field Theories and the Many-Body Problem. (Talks!) In October 2010, we focused on halo systems in the ECT* Workshop on the Limits of Existence of Light Nuclei.

Nuclear EFT is now part of mainstream Chiral Perturbation Theory, and is included in the periodic meetings on the subject. For example, we organized the Working Group on Few-Nucleon Systems, part of the Workshop on Chiral Dynamics, Theory and Experiment, held in July 2000; and the Session on Chiral Physics of the International Conference on the Structure of Baryons, held in March 2002, both at Jefferson Lab, Newport News. A more general meeting spanning various energy scales was the Program on Effective Field Theories in Particle and Nuclear Physics, held at the KITPC in Beijing, August/September 2009.

Various regions of the phase diagram of QCD were discussed at the Pan-American Advanced Study Institute on New States of Matter in Hadronic Interactions, held in January 2002 in Campos do Jordao, Brazil.

An interesting application of EFT is the prediction of charge-symmetry breaking in the reactions pn --> d pi0 and dd --> alpha pi0. In order to develop the theory for the latter, we have organized a series of mini-workshops, starting with Mini-Workshop on Computing sigma(dd --> alpha pi0) and Charge Symmetry Breaking in August 2001 at the INT. The most recent one was the INT Workshop on Charge-Symmetry Breaking in Few-Nucleon Systems in October 2003.
