Measurement of the Branching Fraction Ratios R(D^{+}) and R(D^{*+}) Using Muonic τ Decays. [PDF]

open access: yesPhysical Review Letters
The branching fraction ratios of B[over ¯]^{0}→D^{+}τ^{-}ν[over ¯]_{τ} and B[over ¯]^{0}→D^{*+}τ^{-}ν[over ¯]_{τ} decays are measured with respect to their muonic counterparts, using a data sample corresponding to an integrated luminosity of 2.0  fb^{-1}

HFLAV $τ$ branching fractions fit and measurements of Vus with $τ$ lepton data

open access: yesSciPost Physics Proceedings, 2019
We report the status of the Heavy Flavour Averaging Group (HFLAV) averages of the $\tau$ lepton measurements We then update the latest published HFLAV global fit of the $\tau$ lepton branching fractions (Spring 2017) with recent results by BABAR.

Improved Limits on $B^{0}$ decays to invisible $(+\gamma)$ final states [PDF]

open access: yes, 2012
We establish improved upper limits on branching fractions for B0 decays to final States 10 where the decay products are purely invisible (i.e., no observable final state particles) and for final states where the only visible product is a photon.

Measurement of the branching fraction and CP asymmetry in B0 → π0π0 decays, and an improved constraint on ϕ2 [PDF]

open access: yes, 2017
We measure the branching fraction and CP violation asymmetry in the decay B-0 -> pi(0)pi(0), using a data sample of 752 x 10(6) B (B) over bar pairs collected at the Y(4S) resonance with the Belle detector at the KEKB e(+)e(-) collider.

Search for CP Violation and Measurement of the Branching Fraction in the Decay D^{0}→K_{S}^{0}K_{S}^{0}. [PDF]

open access: yesPhysical Review Letters, 2017
We report a study of the decay D^{0}→K_{S}^{0}K_{S}^{0} using 921  fb^{-1} of data collected at or near the ϒ(4S) and ϒ(5S) resonances with the Belle detector at the KEKB asymmetric energy e^{+}e^{-} collider. The measured time-integrated CP asymmetry is

B decays to final states including D_s^{(*)} and D^* [PDF]

open access: yes, 2000
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 B^0 --> D^{

Measurement of branching fraction and direct CP asymmetry in charmless B+ → K+K−π + decays at Belle [PDF]

open access: yes, 2017
We report a study of the charmless hadronic decay of the charged B meson to the three-body final state K+K-pi(+). The results are based on a data sample that contains 772 x 10(6) B (B) over bar pairs collected at the Y (4S) resonance with the Belle ...

Latest Belle results on Tau decays

open access: yesSciPost Physics Proceedings, 2019
We present preliminary results of a latest measurement at Belle, the branching fraction of rare tau decay, $\tau^- \rightarrow \pi^- \nu_{\tau} \ell^+ \ell^-$ ($\ell = e$ or $\mu$), using a 562 $\rm fb^{-1}$\ data set.
