Welcome to the Wiki pages of JLab FY14 LDRD project "Physics potential of polarized light ions with EIC@JLab."

The aim of the project is to develop the capabilities for deep-inelastic scattering on polarized light ions (deuterium 2H, helium 3) with detection of forward protons and neutrons ("spectator tagging") using the MEIC accelerator and detector/IR design. Such measurements address fundamental questions of nuclear physics: the spin structure of the neutron, the effect of nuclear binding on the nucleon's quark and gluon densities, and coherent multiple scattering at high energies.

Collaborators include

  • Vadim Guzey (Petersburg Nuclear Physics Institute)
  • Doug Higinbotham (JLab Physics)
  • Charles Hyde (Old Dominion University)
  • Wally Melnitchouk (JLab Theory)
  • Kijun Park (JLab / Old Dominion University)
  • Pawel Nadel-Turonski (JLab Physics)
  • Misak Sargsian (Florida International University)
  • Christian Weiss (Lead Scientist, JLab Theory)

The specific tasks performed are

  • Develop cross section models for deep-inelastic processes with polarized light ions (2H, 3He) and spectator tagging at EIC energies, including nuclear binding, final-state interaction, shadowing, and polarization
  • Develop event generators for Monte--Carlo simulations of inclusive, diffractive and exclusive final states
  • Perform process simulations with schematic modeling of the MEIC beam and detector/IR characteristics, to study rates, acceptance, and resolution
  • Analyze pseudodata and quantify physics output of measurements with spectator tagging
