First branching fraction measurement of the suppressed decay Ξc0→π−Λc+ [PDF]

open access: yesPhysical Review D, 2020
The Ξ 0 c baryon is unstable and usually decays into charmless final states by the c → s u ¯ d transition. It can, however, also disintegrate into a π − meson and a Λ + c baryon via s quark decay or via c s → d c weak ...

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}

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.
