Observation of the B s 0 $$ {B}_s^0 $$ → D *+ D *− decay

open access: yesJournal of High Energy Physics, 2023
The first observation of the B s 0 $$ {B}_s^0 $$ → D ∗+ D ∗− decay and the measurement of its branching ratio relative to the B 0 → D ∗+ D ∗− decay are presented.

Dependence of Biofuel Ignition Chemistry on OH-Initiated Branching Fractions

open access: yesFrontiers in Mechanical Engineering, 2021
ion of hydrogen by ȮH is the dominant initiation step in low-temperature oxidation of biofuels. Theoretical chemical kinetics calculations for such reactions provide a direct means of quantifying rates of abstraction, which are critical to modeling ...

Observation of B+->Lambda_c+Lambda_c-K+ and B0->Lambda_c+Lambda_c^-K0 decays [PDF]

open access: yes, 2006
We report first measurements of the doubly charmed baryonic B decays B->Lambda_c+Lambda_c-K. The B+->Lambda_c+Lambda_c-K+ decay is observed with a branching fraction of (6.5+1.0-0.9+-1.1+-3.4)x10^{-4} and a statistical significance of 15.4sigma.

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.

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.

Measurement of the differential branching fraction of the decay Λ0b→Λμ+μ− [PDF]

open access: yes, 2013
The differential branching fraction of the decay Λ0b→Λμ+μ− is measured as a function of the square of the dimuon invariant mass, q2. A yield of 78 ± 12 Λ0b →Λμ+μ− decays is observed using data, corresponding to an integrated luminosity of 1.0 fb−1 ...

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.

Study of the production of $\Lambda_b^0$ and $\overline{B}^0$ hadrons in $pp$ collisions and first measurement of the $\Lambda_b^0\rightarrow J/\psi pK^-$ branching fraction [PDF]

open access: yes, 2015
The product of the $\Lambda_b^0$ ($\overline{B}^0$) differential production cross-section and the branching fraction of the decay $\Lambda_b^0\rightarrow J/\psi pK^-$ ($\overline{B}^0\rightarrow J/\psi\overline{K}^*(892)^0$) is measured as a function of ...

Precision measurement of the branching fractions of J/psi -> pi+pi-pi0 and psi' -> pi+pi-pi0 [PDF]

open access: yes, 2012
We study the decays of the J/psi and psi' mesons to pi+pi-pi0 using data samples at both resonances collected with the BES III detector in 2009. We measure the corresponding branching fractions with unprecedented precision and provide mass spectra and ...
