Measurement of branching fractions of and
BESIII Collaboration, M. Ablikim, M. N. Achasov +685
By analyzing collision data corresponding to an integrated luminosity of 7.33~fb collected with the BESIII detector at center-of-mass energies ranging from 4.128 to…
Study of in the amplitude analysis of
BESIII Collaboration, M. Ablikim, M. N. Achasov +772
We present the first amplitude analysis and branching fraction measurement of decay. The analysis uses a dataset corresponding to an in…
Observation of a threshold enhancement in the spectrum in decays
BESIII Collaboration, M. Ablikim, M. N. Achasov +677
The BESIII experiment analyzed over 2.7 billion ψ(3686) decays and observed a clear resonance-like enhancement near the π⁺π⁻ mass threshold in ψ(3686)→π⁺π⁻J/ψ decays, measuring its…
First measurement of the absolute branching fractions of nonleptonic decays and test of the rule
BESIII Collaboration, M. Ablikim, M. N. Achasov +689
The paper reports the first absolute measurements of the branching fractions for the Σ⁺ → p π⁰ and Σ⁺ → n π⁺ decays using BESIII J/ψ data, and tests the ΔI = 1/2 rule in Σ hyperon…
First measurement of and cross sections via -nucleus scattering at an electron-positron collider
BESIII Collaboration, M. Ablikim, M. N. Achasov +678
Using events collected with the BESIII detector at the BEPCII storage ring, the reactions and $Σ^{+}n\rightarrowΣ^…
Amplitude Analysis of Singly Cabibbo-Suppressed Decay
BESIII Collaboration, M. Ablikim, M. N. Achasov +686
Using a sample of annihilation data corresponding to an integrated luminosity of 4.4 collected with the BESIII detector at the BEPCII collider and produ…
