PAX Plan > 2016 Preparation in progress
COMPASS Plan > 2014 Fixed target, only valence PDFs
J-PARC Plan > 2011 Low s (60-100 GeV2), only unpolarized proton beam
SPASCHARM
NICA
Plan?
Plan >2017
s ~ 140 GeV2 for unpolarized proton beam
s ~ 670 GeV2 for polarized & unpolarized p, d beams, high luminosity (collider)

The following subjects are under consideration for both detectors:
► Polarization effects in heavy ion collisions using spin dependent observables in multi-particle production reactions
► Nucleon spin structure via DY and J/Ψ production processes and others.
NICA-SPD.

Polarization effects in heavy ions collisions with MPD and SPD
The following polarization observables at NICA can be studied with MPD &SPD:• MMT-DY studies; • Λ Polarization as a probe of isotropic matter formation; • Correlations of Λ polarization with charge separation as a complementary signal for CP-violation in dense matter ,• Transverse handedness as a probe for collective orbital momentum of the matter, • Tensor polarization of dileptons as a complementary probe of matter formation,
dilepton production mechanisms and collective orbital momentum.
NICA-SPD.
Proposed for consideration
