Jin Huang M.I.T. For Transversity Analysis Meeting Feb08, JLab

 Trend is consistent  Although some points differs more Transversity Analysis Meeting Jin Huang 2

 Further check show difference come from cut: ◦ BB.ts_accep[]==0 in no longer needed Transversity Analysis Meeting Jin Huang 3

Transversity Analysis Meeting Jin Huang 4

 See my MLE write up, ELOG 298  If ignore charge asymmetry and target polarization  In Transversity case, we should considering them Transversity Analysis Meeting Jin Huang 5

Transversity Analysis Meeting Jin Huang 6

Transversity Analysis Meeting Jin Huang 7

Transversity Analysis Meeting Jin Huang 8  Considering our momentum transfer is not always perpendicular to target spin  Light colored points are with this effect  Difference is suppressed for SSA since this effect is small for vertical polarization

 Taking one pair of modulation ◦ Coinc Pi-, 2 nd X bin ◦ Then try to illustrate their correlation with a 2D PDF Transversity Analysis Meeting Jin Huang 9
