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 Tau Lepton Electronic Branching Fraction [PDF]

open access: bronzePhysical Review Letters, 1993
The tau lepton electron branching fraction has been measured with the CLEO II detector at the Cornell Electron Storage Ring as [ital B][sub [ital e]]=0.1749[plus minus]0.0014[plus minus]0.0022, with the first error statistical and the second systematic.

First Measurement of the Absolute Branching Fraction of Λ→pμ^{-}ν[over ¯]_{μ}.

open access: yesPhysical Review Letters, 2021
The absolute branching fraction of Λ→pμ^{-}ν[over ¯]_{μ} is reported for the first time based on an e^{+}e^{-} annihilation sample of 10×10^{9}  J/ψ events collected with the BESIII detector at sqrt[s]=3.097  GeV.

Branching fractions of B meson decays in Mesogenesis

open access: yesJournal of High Energy Physics, 2023
Production of the matter-antimatter asymmetry in the B-Mesogenesis mechanism is directly related to the branching fraction of seemingly baryon number violating decays of B mesons into a light Standard Model baryon and missing energy.

Measurement of the B_{s}^{0}→μ^{+}μ^{-} Branching Fraction and Effective Lifetime and Search for B^{0}→μ^{+}μ^{-} Decays. [PDF]

open access: yesPhysical Review Letters, 2017
A search for the rare decays B_{s}^{0}→μ^{+}μ^{-} and B^{0}→μ^{+}μ^{-} is performed at the LHCb experiment using data collected in pp collisions corresponding to a total integrated luminosity of 4.4  fb^{-1}.

Measurement of branching fractions of Λ c + $$ {\Lambda}_{\textrm{c}}^{+} $$ decays to Σ+K+K − , Σ+ ϕ and Σ+K+ π − (π 0)

open access: yesJournal of High Energy Physics, 2023
Based on 4.5 fb −1 data taken at seven center-of-mass energies ranging from 4.600 to 4.699 GeV with the BESIII detector at the BEPCII collider, we measure the branching fractions of Λ c + $$ {\Lambda}_c^{+} $$ → Σ+ + hadrons relative to Λ c + $$ {\Lambda}

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 ...

Semileptonic decay of Ds+→π0ℓ+νℓ via neutral meson mixing

open access: yesPhysics Letters B, 2020
Based on the mechanism of neutral meson mixing, we predict the branching fraction of the semileptonic decay of Ds+→π0ℓ+νℓ (ℓ=e, μ) using recently measured branching fraction of Ds+→ηe+νe by BESIII experiment.
