Measurement of the branching fraction for ψ(3770)→γχc0

open access: yesPhysics Letters B, 2016
By analyzing a data set of 2.92 fb−1 of e+e− collision data taken at s=3.773 GeV and 106.41×106 ψ(3686) decays taken at s=3.686 GeV with the BESIII detector at the BEPCII collider, we measure the branching fraction and the partial decay width for ψ(3770)→

Measurement of the inclusive branching fraction for ψ(3686)→KS0+anything

open access: yesPhysics Letters B, 2021
Using 5.9 pb−1 of e+e− annihilation data collected at center-of-mass energies from 3.640 to 3.701 GeV with the BESIII detector at the BEPCII Collider, we measure the observed cross sections of e+e−→KS0X (where X=anything).

Measurement of the branching fraction of D + → τ + ν τ

open access: yesJournal of High Energy Physics
By analyzing e + e − collision data with an integrated luminosity of 7.9 fb −1 collected with the BESIII detector at the center-of-mass energy of 3.773 GeV, the branching fraction of D + → τ + ν τ is determined as B $$ \mathcal{B} $$ = (9.9 ± 1.1stat ± 0.

Measurement of the tau branching fractions into leptons [PDF]

open access: yesPhysics Letters B, 2001
Using data collected with the L3 detector near the Z resonance, corresponding to an integrated luminosity of 150pb-1, the branching fractions of the tau lepton into electron and muon are measured to be B(tau->e nu nu) = (17.806 +- 0.104 (stat.) +- 0.076 (syst.)) %, B(tau->mu nu nu) = (17.342 +- 0.110 (stat.) +- 0.067 (syst.)) %.

Recent results from BABAR [PDF]

open access: yesEPJ Web of Conferences, 2020
The BABAR Collaboration at SLAC continues to produce a wide variety of publications on interesting and unique topics despite having ceased data-collection operations more than 10 years ago. Presented here are the results of three recent studies.

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.

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.
