Title: Analysis of Nucleon Resonances
Description: The objectives of Analysis of Nucleon Resonances (N*) are twofold. The first is to perform dynamical coupled-channels analysis of meson production reaction data for extracting the parameters of nucleon resonances. The second objective is to develop theoretical interpretations of the determined resonance parameters in terms of hadron structure calculations such as the constituent quark model and Lattice QCD calculations.
This project will provide information for understanding the non-perturbative aspects of QCD.
In particular, the extracted N-N* form factors will reveal the dynamical origins of quark confinement and the meson cloud associated with the spontaneously breaking of chiral symmetry.
This project is needed to reach milestones HP3 and HP7 by 2012 set in DOE's long-range plan
of 2010.
Current: undetermined amount
Justification: The analysis will be carried out by solving a large set of coupled integral equation in momentum-space an performing chi-squared fits , with
about 200 parameters, to very extensive world data of pion-nucleon scattering and electromagnetic meson production reactions.
The calculation at each energy and each set of parameters involve an inversion of an about 1000*1000 complex matrix. This has to be repeated many times in searching the best-fit parameters in
chi-squared fit to very extensive data (about 60,000 data points) using MINUIT.
Requested: 8000
A specific reason has been given:
to explore the use of Fusion for
the proposed project
This needs to be approved and the final allocation amount decided upon.
