The Spin Physics Working Group seeks to understand the spin structure of the proton through polarized proton collisions
at RHIC. As the world's first high-energy polarized hadron collider, RHIC provides direct access to the gluon,
allowing measurement of the gluon's contribution to the spin of the proton. The 500 GeV program, starting in 2009,
will produce W bosons and probe the spin contributions of anti-up and anti-down quarks separately. The transverse-spin
structure of the proton, still poorly understood, is also being explored at RHIC.
Here is a list of a few of the physics analyses being performed by the Spin Physics Working Group, some of which overlap with
other working groups in PHENIX.
(Collaborators should see the internal page for more details.)
- Double-longitudinal asymmetry, ALL, of neutral pions, etas, charged pions, single electrons, J/Psi, single muons
- Parity-violating single-longitudinal asymmetry, AL, in W boson production, sensitive to the polarization of light sea quarks (u-bar, d-bar) in the proton
- Single-transverse asymmetry, AN, of charged hadrons, neutral pions, J/Psi, forward neutrons
- Back-to-back di-hadron asymmetry to probe the gluon Sivers function
- Interference fragmentation function asymmetry, sensitive to the transversity distribution
- Lambda polarization transfer
- Double-longitudinal kT asymmetry
- Cross sections for neutral pions, charged hadrons, etas, direct photons, W bosons, and forward neutrons
