[LCRC Accounts] Yearly Allocation Request for anl-dcc
Hello, A yearly allocation for the LCRC cluster has been requested with the following updated information: Submitter/PI: Tsung-Shung Lee Project Name: anl-dcc Division: PHY Project title: Dynamical coupled-channel analysis of hadrons at Argonne Associated funding: DOE Other Systems: NERSC Science: This project will develop theoretical approaches for studying the spectrum and structure of excited baryon states within the fundamental theory of strong interaction; Quantum Chromodynamics (QCD). The results will provide information for advancing our understanding of strong interactions and structure of visible matter in universe. This is part of ANL's effort to achieve a DOE milestone HP7. Project description: In 2013-2014, we have completed a 8-channel analysis which extract nucleon resonances from data of pi-N and gamma-N reactions. In 2015, we need to continue this effort to extract N-N* form factors for testing the hadron structure calculations using Lattice QCD and various QCD-based models. In 2014, we have also extended our coupled-channel model to include the strangeness S=-1 channels to extract hyperon resonances. In 2015, we will apply this model to make predictions for new experiments on kaon-nucleon reactions at the new hadron facility J-PARC in Japan. The computations involve solving a large set of coupled-channel integral equations and searching for parameters to fit the world data of meson production of pion-nucleon and photon-nucleon reactions. The calculations account for eight meson-baryon channels and cover energies up to invariant mass W= 3 GeV. Large complex-matrix (1000 by 1000) need to be inverted many times in chi**2-fit to very extensive data (about 110,000 data points) . Standard fortran codes have been developed to perform parallel computations with the facilities at LCRC. The project will have 4 members.
