Parity Violation
Research based around the Strange Quark contribution to the Nucleon Electro-Magnetic properties using Parity Violation experiment Gzero at Jlab. Results are published and complete flavor separation to the lightest three quarks is done. Now, writing the PRC.

SIDIS
Still related to the strange sea quarks, but this time via Semi-Inclusive Deep Inelastic Scattering (SIDIS) of electrons off polarized deuteron or proton targets. Hadron production in DIS is described by the absorption of a virtual photon by a point-like quark followed by the fragmentation of this quark into hadronic final states. The first process is characterized by the quark distribution functions and the second process is characterized by fragmentation functions. Measuring multiplicities for several hadron species (pions and kaons) allows the control of the fragmentation functions used in the extraction of the individual quark and antiquark contributions to the nucleon spin.
