Formulation of the OK action

We implement numerically the Fermilab formulation of the OK action for the heavy quarks such as bottom and charm quarks on the lattice. The key issue is to determine the coefficients of the higher order terms in a reliable way. We will take over this challenging problem to calculate the V_cb with extremely high precision.

B meson mass

Once we formulate the heavy quarks on the lattice using the OK action, we will calculate the B meson spectrum to check the reliability of the OK action formalism.

f_B

We will also calculate the B meson decay constants f_B.

V_cb

Our main mission of this project is to calcualte V_cb with extremely high precision.

B-B mixing

We also plan to calculate the B-B meson mixing parameters using the OK action formalism.
