Overview
Welcome to the Wiki pages of JLab LDRD Project LD1601 "Nuclear gluons with charm at EIC."
The aim of the project is to demonstrate the feasibility of novel measurements of the quark
and gluon densities in nuclei (A > 1) with a future Electron-Ion Collider (EIC):
- Direct measurements of nuclear gluons at x > 0.1 using heavy quark production (open charm, beauty);
- Flavor decomposition of nuclear quarks at x ~ 0.1 using semi-inclusive deep-inelastic scattering (pions, kaons).
Precise measurements of the nuclear quark and gluon densities are a central goal of nuclear physics and address fundamental questions regarding Quantum Chromodynamics (QCD) and the origin of nuclear binding. The nuclear modifications (nucleus =/= sum of A nucleons) offer insight into the presence of non-nucleonic degrees of freedom in nuclei (EMC effect, x > 0.2), the QCD structure of the nucleon-nucleon interaction (antishadowing, x ~ 0.1), and the emergence of coherent gluon fields at high energies (shadowing, x < 0.01). The proposed new measurements use information about the hadronic final state in deep-inelastic scattering and are made possible by the unique capabilities provided by EIC (collision energy, luminosity, detection of final-state hadrons).
The project is carried out in a collaborative effort of experimental and theoretical
nuclear physicists. Collaborators include:
- Eugene Chudakov (JLab Physics)
- Sergey Furletov (JLab Physics)
- Doug Higinbotham (JLab Physics)
- Charles Hyde (Old Dominion University)
- Dien Nguyen (University of Virginia & JLab)
- Marco Stratmann (University at Tubingen, Germany)
- Mark Strikman (Penn State University)
- Christian Weiss (Lead Scientist, JLab Theory)
The specific tasks performed are:
- Adapt simulation tools for heavy quark production in ep scattering (HVQDIS Monte Carlo,
F2c code) to eA scattering at EIC, with schematic modeling of charm detection and reconstruction
- Adapt MC tools for semi-inclusive ep DIS to eA at EIC
- Simulate nuclear ratio measurements of open charm production and semi-inclusive
DIS at EIC
- Assess systematic and theoretical accuracy of nuclear ratio measurements at EIC
and quantify physics impact
