Cuts
-
*Semileptonic (Ds mu) mass
plot (250 pb-1), Cuts:
Look for the section 3 - Selection of (mu Ds X) events (Ds -> phi pi)
-
J/psi
-> mu+mu- (~200 pb-1) (these 770k candidates are with tight cuts. Currently
have ~1.2M in this sample)
-
Lambda_b
-> J/psi Lambda (~200 pb-1). Cuts are here
-
B mass plots can be found here.
The /\_b plot here has been made with different cuts than in the previous
link. B_d-J/psi K_S plot made more consistent with the rest here.
