Title:
"Direct CPV in B->J/psi K"
Abstract:
We study direct CP violation in b \to c \overline{c} s transition
by searching for a charge asymmetry in the decay B^{\pm} \to
J/\psi K^{\pm}. The results presented are based on a large data set
of p \overline{p} collisions recorded by the D0 detector during
the Run II of Tevatron collider.
