Projection of STAR sensitivity for A_L for W+,W-  at mid rapidity for LT=10/pb and pol=60% 

Common assumptions:

• LT=10 pb ^-1
• beam pol=60%
• W reco efficiency 70%
• no losses due to the vertex cut 
• integrated over eta [-1,+1] 
• see remaining details in study 9 sensitivity of STAR at forward & mid rapidity
