Introduction Initial results Dedic<strong>at</strong>ed experiments Future 6 <strong>GeV</strong> <strong>12</strong> <strong>GeV</strong> <strong>EIC</strong> Conclusion<br />
Summary <strong>and</strong> conclusions<br />
JLab results:<br />
◮ Twist-2 dominance <strong>at</strong> rel<strong>at</strong>ive low Q 2 (a few <strong>GeV</strong> 2 )<br />
◮ Many polariz<strong>at</strong>ion observables needed: both target <strong>and</strong> beam<br />
◮ Different beam/collision energies needed<br />
◮ Absolute cross-sections better than asymmetries<br />
Opportunities with <strong>EIC</strong>:<br />
◮ Lower x <strong>at</strong> sufficiently high Q 2<br />
◮ Higher Q 2 lever arm to better underst<strong>and</strong>/h<strong>and</strong>le higher twists<br />
Challenges of <strong>EIC</strong>:<br />
◮ Luminosity (small cross-sections)<br />
◮ Very <strong>for</strong>ward recoil detection needed<br />
