  3. Transverse Momentum Dependent (TMD) Parton Distributions • TMD PDFs link • Intrinsic motion of partons • Parton spin • Spin of the nucleon • Multi-Dimension structure • Probes orbital motion of quarks • A new phase of study, fast developing field • Great advance in theories (factorization, models, Lattice ...) • Not sys. studied until recent years • Semi-Inclusive DIS (SIDIS): HERMES, COMPASS, Jlab-6GeV, ... • p-p(p_bar) process : FNAL, BNL, ... in DIS Nucleon -> Plate Transverse motion Preserved Jin Huang <jinhuang@jlab.org>

  4. Nucleon Spin Leading-Twist TMD PDFs Quark Spin h1= Boer-Mulders f1 = h1L= Worm Gear (Kotzinian-Mulders) Helicity g1 = h1= Transversity f1T= g1T= h1T= Sivers Worm Gear Pretzelosity Jin Huang <jinhuang@jlab.org>

  5. Tool: Semi-inclusive DIS (SIDIS) k’ • Gold mine for TMDs • Access all eight leading-twist TMDs through spin-comb. & azimuthal-modulations k q, Q2 Ph/z W xP Scattering Plane W’ P Jin Huang <jinhuang@jlab.org>

  6. Polarized 3He Target • High 1036 N/cm2/spolarized luminosity • Achieved performance: • High polarization > 60% achieved • Supports both long. & trans. spin • Frequent spin flip Effective pol. neutron target ~90% ~1.5% ~8% Achieved: stable pol. 60% with spin flip Jin Huang <jinhuang@jlab.org>

  7. The SoLID Spectrometer • Large acceptance: enable 4D-mapping • Full azimuthal angular coverage: small systematics • Share hardware with PVDIS(N. Liyanage Talk Friday) • GEM: high rate tracking • LC: In field calorimeter • Cerenkov: PID • MRPC: TOF, PID @ low p • C: Calorimeter 12º 6.6º 22º 13º e- Jin Huang <jinhuang@jlab.org>

  8. Phase space coverage • Natural Extension of E06-010See A. Puckett talk, last session • Much wider phase space • Also data at low and high z value to access target frag. and exclusive channels. • Both transverse and longitudinal polarized target.Study 6/8 leading twist TMDs Jin Huang <jinhuang@jlab.org>

  9. h1T = Transversity • The third PDFs in addition to f1 and g1L • 10% d quark tensor charge with world data • Test Soffer’s inequality |h1T| <= (f1+g1L)/2 at large x Jin Huang <jinhuang@jlab.org>

  10. f1T= Sivers Function • Correlation between nucleon spin with quark angular momentum • Important test for factorization • Different sign with twist-3 quark-gluon corr. dis. at high PT? • Kang,Qiu, Vogelsang and Yuan: arxiv: 1103.1591 • Search for sign change, also PT weighted moments (Boer, Gamberg, Musch) Jin Huang <jinhuang@jlab.org>

  11. Worm-gear functions • Dominated by real part ofinterference between L=0 (S) and L=1 (P) states • No GPD correspondence • Lattice QCD -> Moments of worm-gear TMDs • Model Calculations -> h1L =? -g1T • Connections with Collinear PDFs through WW approx. and LIR. h1L= Worm Gear Center of points: g1T= Center of points: Jin Huang <jinhuang@jlab.org>

  15. Recent Progress I:Magnet Choices and Simulation Framework • Possible choices of magnets • BABAR, CLEO, CDF, ZEUS, Hall D, New design • Field and acceptance studied for the first four • GEMC based simulation framework • Allow for quantitative decisions on magnet acceptance • Rates/background studies • see Z.W.

  16. Recent Progress II:Cerenkov Detector Design • Good progress with optics design • Near perfect optics eff. achieved with Winston cone + 6x6’’ det. • Viable photo detectors • Field-resistive PMTs or GEM-CsI detectors • Next stage is R&D and prototyping. Plots by S. Malace • 13.6’’ Winston cone • 6x6’’ detector

  17. Other Major Progress • GEM • R&D Efforts from UVa/INFN/JLab are combined with the GEM R&D for the Super-BigBite & EIC • See talk by N. Liyanage (Friday) • EM calorimeters • Choices of Shashlik & SciFi (Pb or Fe) studied • The Shashlik design is more favored • MRPC • Onsite test in November • DAQ system • Follows the Hall D path Jin Huang <jinhuang@jlab.org>

  18. Summary • SIDIS is a powerful tool to study Parton dynamics in the amplitude level (TMDs) • Spin-OAM correlation, flavor dependence etc. • SoLID is an ideal device to study SIDIS • High luminosity, large acceptance and full azimuthal coverage • Will provide ultimate precision (4-D) of SSA/DSA, at high-x (valence), low Q2 region, which is crucial input to global analysis. • Test SIDIS factorization, PT dependence at JLab12 (complementary to SIDIS programs in Hall B/C) • Integrated Effort in SoLID R&D with PVDIS • Steady progress • In preparation for the Director Review.
