After some back-and-forth with the PI (see ticket# 45322), he determined that he'll need 200,000 corehours for this project, not 10,000 as initially requested. OK to approve this project? Note that the limit that the Allocation Committee decided at the last meeting that we can approve is 150K, so that's the most we could give now. If OK to approve, I'll use the following, unless someone has corrections: Cat/Subcat: P/Phy POC: Steve Pieper Priority: 3 Amount: 150,000 John On Mon, Apr 26, 2010 at 02:24:00PM -0500, [email protected] wrote:

Hello,

A new project on the LCRC cluster has been requested. Please forward the information on to the LCRC Allocation sub-committee.

Applicant's name: Tsung-Shung Lee Applicant's institution: ANL Applicant's division: PHY Project Name: EBAC Project title: Analysis of Nucleon Resonances Associated funding: U.S. Department of Energy, Office of Nuclear Physics Division, under Contract DE-AC02-06CH11357 Other Systems: workstation theory9 of PHY , and NERSC Science: The objective of this project is to extract nucleon resonance information from world data of meson production reactions for advancing our understanding of the origin of hadron matter within Quantum Chromodynamics (QCD), the fundamental theory of strong interactions Project 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. Project URL: http://ebac-theory.jlab.org Requested allocation: 10000 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.

The requester has used 0 hours of their initial startup project.

In addition to approving an initial amount, please specify a Category and Subcategory for this project. For a list of the current selection of approved categories, please see:
