polarization<br />
- detector acceptance generates<br />
artifical polarization<br />
- analyse cross section with different<br />
polarization hypothesis<br />
(causes 4-25% difference)<br />
next step:<br />
measure:<br />
dσ/dp T (all J/ψ)<br />
σ(prompt J/ψ)<br />
σ(J/ψ from b)<br />
- fit for transversal and<br />
longitudinal polarization using<br />
templates from MC<br />
