Kaon SIDIS measurement with the SoLID

ORAL

Abstract

The proposed Solenoidal Large Intensity Device (SoLID) at Jefferson Lab will study the Transverse Momentum Dependent parton distribution functions (TMDs) in a wide kinematic range with unprecedented precision. The high luminosity and large acceptance SoLID spectrometer with the upgraded CEBAF will allow precise multi-dimensional measurements of the azimuthal asymmetries in the valence quark region. Charged pion SIDIS experiments with longitudinally and transversely polarized proton and 3He targets are already planned. In addition, a charged kaon SIDIS experiment using transversely polarized proton and 3He targets was recently proposed. These measurements combined with the pion measurements will provide full flavor decomposition of TMDs in light quark-sector. The kaon data will have unique sensitivity to strange and sea quarks. In particular since K- is composed of only sea quarks, it will enable us to explore their role in the nucleon. The kinematic coverage of this dataset will span different fragmentation regimes (current, central and target) providing important information to study the validity of factorization and guide development of TMD theory. In this talk, the experimental overview and projected uncertainties of Collins and Sivers asymmetries will be presented.
