• Bring together scientists from different fields
• ODU has hired ~6 data science faculty
• Need help to learn how to involve people from different disciplines

David Richards

• “Understanding the Glue That Binds Us All: The Next QCD Frontier in Nuclear Physics”

Christian Weiss

• Imaging technologies in computation
• Subnuclear systems
  • Scales
  • Scattering experiments
• Workflow inmeasurements
• Tesselation
• Scales
  • Organisms- Cells
  • Molecular - Atoms
  • Nuclear - Subnuclear
• Mission: Explore subnuclear systems
  • Strong interaction : quarks,gluons
  • Understand proton neutron as emergent phenomena
• Interest
  • Basic building blocks of matter
  • nuclear structure and reactions, nuclear energy
• Subnuclear systems
  • Unusual dynamical system
  • Relativity: Energy = mass, conversion processes. Proton is ‘cauldron’ filled with radiation energy and matter/antimatter
  • Only average properties are measurable: densities,correlations
• Scattering experiments
  • Electrons collide on protons
  • Scatterings are gathered from detectors
  • JLab 12GeV accelerators
  • Information Recorded:
    • Distribution based on type and momentum -> Phase space distributions
    • The “expression” of proton’s internal structure
    • 10^6 - 10^9 experiments in JLab
• Workflow: Measurements
  • Theory: Model of proton structure (parameters that need to be verified experimentally)
  • Predicitions for scattering probabilities
  • Phase space distributions (meeting ground between theory and experiments)
  • Scattering Experiments -> Raw Data
  • Reconstruction baseed on the raw data
  • Modify theoretical model based on observations
  • “Final” picture of proton from synthesis of multi
