B C and Excited B States — a Tevatron Review

Weak phases γ and α from B + , or B 0 and B s decays

An improved method is presented for determining the weak angle γ of the unitarity triangle using decay rates for B+ → Kπ,B+ → K+K̄0 and B+ → π+η (or B0 → Kπ and Bs → Kπ), their CP-conjugate modes and the CP-averaged rate for B → π±π0. Using SU(3) symmetry, the annihilation (color-suppressed) contribution in B+(B0) → Kπ decays is subtracted away. Electroweak penguin effects are included in a mode...

B decays to excited charm mesons

The spectroscopy of hadrons containing one heavy quark Q, in the infinite mQ limit, is simplified by the decoupling of the heavy quark spin ~sQ from the angular momentum of the light degrees of freedom (quarks and gluons) ~sl = ~ J − ~sQ. In this heavy quark theory (HQET) the states are classified by both ~ J and ~sl, and the hadrons corresponding to the same sl belong to degenerate doublets. I...

Semileptonic B Decays to Excited Charm Mesons

Exclusive semileptonic B decays to the lightest excited charmed mesons are investigated at order ΛQCD/mQ in the heavy quark effective theory. At zero recoil, ΛQCD/mQ corrections to the matrix elements of the weak currents can be written in terms of the leading Isgur-Wise functions for the corresponding transition and meson mass splittings. The differential decay rates are predicted, including Λ...

Semileptonic B decays to excited charmed mesons

Exclusive semileptonic B decays into excited charmed mesons are investigated at order ΛQCD/mQ in the heavy quark effective theory. Differential decay rates for each helicity state of the four lightest excited D mesons (D1, D ∗ 2, D∗ 0, andD ∗ 1) are examined. At zero recoil, ΛQCD/mQ corrections to the matrix elements of the weak currents can be written in terms of the leading IsgurWise function...
