New results on the search for Bs0 → µ+µ− from LHCb

open access: yesEPJ Web of Conferences, 2013
A search for the rare decays Bs0 → µ+µ− and B0 → μ+μ− is performed with the LHCb experiment using 1.1 fb−1 of data collected at √s = 8 TeV and 1.0 fb−1 of data collected at √s = 7 TeV.

Measurement of the absolute branching fraction of Λc+→pKS0η decays

open access: yesPhysics Letters, Section B: Nuclear, Elementary Particle and High-Energy Physics, 2021
Based on 586 pb−1 of e+e− annihilation data collected at a center-of-mass energy of s=4.6GeV with the BESIII detector at the BEPCII collider, the absolute branching fraction of Λc+→pKS0η decays is measured for the first time to be B(Λc+→pKS0η)=(0.414±0 ...

Measurement of the absolute branching fraction for Λc+→Λμ+νμ

open access: yesPhysics Letters, Section B: Nuclear, Elementary Particle and High-Energy Physics, 2017
We report the first measurement of the absolute branching fraction for Λc+→Λμ+νμ. This measurement is based on a sample of e+e− annihilation data produced at a center-of-mass energy s=4.6 GeV, collected with the BESIII detector at the BEPCII storage ...

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.
