We report a study of semileptonic B decays to P-wave D** mesons. Semileptonic decay to D*_2 meson is observed for the first time. The result is obtained using the full reconstruction tagging method from a data sample that contains 657 millions BB pairs collected at the Upsilon(4S) resonance with the Belle detector at the KEKB asymmetric-energy e+ e- collider.

The precise determination of CP violation in the B meson system has been one of the goal of particle physics in the last decade. The Standard Model description of the CP violation phenomenology has been proved to be successful by accurate measurements using $B^+$ and $B^0$ decays at the B factories. So far, comparable experimental knowledge in the $B_s$ sector has been lacking, but the...
