Rare B Decays at BaBar

open access: yes, 2009
I present some of the most recent BABAR measurements for rare B decays. These include rate asymmetries in the B decays to K(∗)l+l− and K+− and branching fractions in the B decays to l+ν, K(1270)+π− and K(1400)+ π−.

Non-factorisable contributions of strong-penguin operators in Λ b → Λℓ + ℓ − decays

open access: yesJournal of High Energy Physics
We investigate for the first time a certain class of non-factorisable contributions of the four-quark operators O $$ \mathcal{O} $$ 3−6 in the weak effective Hamiltonian to the Λ b → Λℓ + ℓ − decay amplitude.

CP violation in K → μ + μ − with and without time dependence through a tagged analysis

open access: yesJournal of High Energy Physics
We point out that using current knowledge of B K L 0 → μ + μ − $$ \mathcal{B}\left({K}_L^0\to {\mu}^{+}{\mu}^{-}\right) $$ and B K L 0 → γγ $$ \mathcal{B}\left({K}_L^0\to \gamma \gamma \right) $$ , one can extract short-distance information from the ...

Constraints on "rare" dyon decays

open access: yes, 2008
We obtain the complete set of constraints on the moduli of N = 4 superstring compactifications that permit "rare" marginal decays of ¼-BPS dyons to take place. The constraints are analysed in some special cases.

Rare Hadronic B Decays [PDF]

open access: yes, 2006
Rare hadronic B-meson decays allow us to study CP violation. The class of B-decays final states containing two vector mesons provides a rich set of angular correlation observables to study.
