ROMA - 1328 / 01 B d – B̄ d Mixing and the B d → J / ψK s Asymmetry in General SUSY Models

We present a next-to-leading order determination of the gluino-mediated SUSY contributions to Bd – B̄d mixing and to the CP asymmetry aJ/ψKs in the framework of the mass-insertion approximation. Using hadronic matrix elements recently computed on the lattice, we obtain improved constraints on the squark-mass splittings.

B Decays to Final States including D

The e+e− annihilation data recorded with the BABAR detector has been used to study B decays to D (∗)± s and D mesons. The production fraction of inclusive D (∗)± s and the corresponding momentum spectra have been determined. Exclusive decays B0 → D∗−D s have been identified with a partial reconstruction technique and their branching fractions have been measured. We also report branching fractio...

Fig. 1 Let ABCD be a circumscribed quadrilateral, that is, a quadrilateral which has an incircle. Let this incircle have the centerO and the radius ρ and touch its sides AB, BC, CD, DA at the points X, Y, Z, W, respectively. Then, for some very obvious reasons, OX ⊥ AB, OY ⊥ BC, OZ ⊥ CD, OW ⊥ DA and OX = OY = OZ = OW = ρ. Moreover, AW = AX, BX = BY, CY = CZ, DZ = DW, since the two tangents from...

Studies of Three-Body B^+→D ̅^* 〖(2007)〗^0 K^+ K ̅^0 and B^0→D^* 〖(2010)〗^- K^+ K ̅^0 Decays

We analyze three-body decays of and . Under the factorization approach, there are tree level diagrams for these decay modes and the transition matrix element of decay is factorized into a form factor multiplied by decay constant and form factor multiplied into weak vertices form factor. The transition matrix element of decay is also factorized into a form factor multiplied into weak vertic...
