The RHIC SPIN Program: Achievements and Future Opportunities

Understand

Time and again, spin has been a key element in the exploration of fundamental physics.

• Spin-dependent observables have often revealed deficits in the assumed theoretical framework and have led to novel developments and concepts.
• Spin is exploited in many parity-violating experiments searching for physics beyond the Standard Model or studying the nature of nucleon-nucleon forces.
• The RHIC spin program plays a special role in this grand scheme: it uses spin to study how a complex many-body system such as the proton arises from the dynamics of QCD.
