B ¯ → D ¯ D $$ \overline{B}\to \overline{D}D $$ decays and the extraction of f d /f u at hadron colliders

Journal of High Energy Physics
We perform a detailed model-independent phenomenological analysis of B ¯ → D ¯ D $$ \overline{B}\to \overline{D}D $$ decays. Employing an SU(3) F analysis including symmetry-breaking contributions together with a conservative power counting for various ...

B ¯ s , d 0 $$ {\overline{B}}_{s,d}^0 $$ → J/ψμ + μ − decays in QCD factorization

Journal of High Energy Physics
Motivated by the first LHCb searches for the rare B ¯ s , d 0 $$ {\overline{B}}_{s,d}^0 $$ → J/ψμ + μ − decays, we perform a detailed study of these processes within the QCD factorization formalism.

The Standard Model prediction for the rare decay B → X s ν ν ¯ $$ B\to {X}_s\nu \overline{\nu} $$

Journal of High Energy Physics
We present updated and comprehensive Standard Model predictions for the inclusive rare decay B → X s ν ν ¯ $$ B\to {X}_s\nu \overline{\nu} $$ . Using a state-of-the-art determination of the short-distance coefficient, including NLO QCD and electroweak ...

Progress in bottom-quark fragmentation

, 2005
I review recent progress on bottom-quark fragmentation in e+e- annihilation, top-quark decay and H -> b bbar processes. I discuss the implementation of collinear and soft resummation, and the inclusion of non-perturbative information taken from LEP and SLD data.

Bottom-hadron production in high-energy pp and heavy-ion collisions [PDF]

EPJ Web of Conferences
The hadro-chemistry of bottom quarks produced in hadronic collisions encodes valuable information on the mechanism of color-neutralization in these reactions.

Measurements of the bottom quark mass

, 2000
I will review new measurements of the b quark mass, presented at this conference by ALEPH and DELPHI. A large set of observables has been used and detailed studies on jet algorithms have been performed. These measurements at the Z peak are consistent with the results obtained at the Upsilon scale when assuming the running of the b quark mass as ...
