Nuclear Theory Group

The BNL nuclear theory group conducts a vigorous research program in all areas of high energy Quantum Chromodynamics (QCD) including the spin and three dimensional structure of the hadron, the many-body dynamics of quarks and gluons in hadrons and nuclei at high energies, the structure of the QCD phase diagram in extreme conditions, and the properties of quark-gluon matter in and out of equilibrium.

Group members have strong interdisciplinary research interests and collaborations in the structure and dynamics of strongly correlated systems in condensed matter physics, atomic physics and cosmology. The research program of the group is strongly aligned with the polarized proton and heavy-ion experimental programs at RHIC, with explorations of QCD at the LHC, and in the physics of a future Electron-Ion Collider. There is also a strong synergy between research in the Nuclear Theory Group and the research program of the High Energy Theory Group and the RIKEN-BNL Center.

Nuclear Theory Group members actively participate in the new BNL/SBU Center for Frontiers in Nuclear Science.

Chiral Magnetic Effect

Chiral Magnetic Effect

Charge separation effect — domain walls that separate the region of θ≠0 from the outside vacuum with θ=0 become charged in the presence of an external magnetic field, with the surface charge density ~eθ/Π·eΒ/2Π.

Rapidity Evolution of the Spatial Strong Color Field Correlations Probed by a Quark-anti Quark Probe

This illustrates the degree of fluctuations and shows how the correlation length decreases dynamically with increasing rapidity Y. More information on the calculation
