Search for quark compositeness with polarized beams at RHIC
  Around 1999, thanks to the RHIC Spin Collaboration (RSC), the Relativistic Heavy Ion Collider (RHIC) will be used as a polarized proton-proton collider. A new handed interaction between quark subconstituents, which could explain the excess of large E_T jet found by the CDF collaboration, could be at the origin of some small parity violating effects in one-jet inclusive production. Using spin asymmetries it is possible, at RHIC, to disentangle this new effect from the Standard Model prediction due to QCD-ElectroWeak interferences.
