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.

Research Paper: Direct Decay of The Higgs Boson into Upsilon Meson via Fragmentation [PDF]

open access: yesفیزیک کاربردی ایران, 2022
One of the dominant modes of decay of the standard model Higgs boson is its decay into b  pair. Subsequently, either b or  can fragment directly into the upsilon meson.

Direct decay of the Higgs boson via fragmentation [PDF]

open access: yesمجله علوم و فنون هسته‌ای, 2023
In the CMS detector, the branching fractions of Higgs boson to J/ψ(1S) and cc pairs have been measured equal to 1.8×10-3 and 2.89 × 10-2, respectively. Theoretically, one possible scenario for direct production J/ψ(1S) is that the Higgs boson initially ...

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 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}

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.

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 ...

Measurements of the branching fractions of B+→ppK+ decays [PDF]

open access: yes, 2013
The branching fractions of the decay B+ → pp̄K+ for different intermediate states are measured using data, corresponding to an integrated luminosity of 1.0 fb-1, collected by the LHCb experiment. The total branching fraction, its charmless component Mpp̄
