Title: Extraction of the pretzelosity distribution from experimental data

We attempt an extraction of the pretzelosity distribution ($$h^{\perp}_{1T}$$) from preliminary COMPASS, HERMES, and JLAB experimental data on $$\sin(3\phi_h - \phi_S)$$ asymmetry on proton and deuteron targets. The resulting distributions, albeit big errors, show tendency for up quark pretzelosity to be positive and down quark pretzelosity to be negative. A model relation of pretzelosity distribution and Orbital Angular Momentum of quarks is used to estimate contributions of up and down quarks.
