Hallo,
 
Received questions:

- how we are sure not to have contamination from the acceptance
in the measurement of cos(phi) and cos(2phi)
unpolarized asymmetries;
- why Sivers 2007 result is not updated with more statistics;
- if the COMPASS cuts were used
in the new prediction from Bacchetta
for the 2h;

This last question refers to the slide 25,
in which I have put new predictions
for the 2h asymmetries, received at the very last minute
from Bacchetta.

regards,
Federica
