First Observation of and Determination of the Branching Fraction of
BESIII Collaboration, M. Ablikim, M. N. Achasov +685
Using 20.3~fb of annihilation data collected at a center-of-mass energy of 3.773~GeV with the BESIII detector, we report the first observation of the semileptonic d…
Observation of a Doubly-strange Hyperon in
BESIII Collaboration, M. Ablikim, M. N. Achasov +758
Based on a sample of events collected with the BESIII detector at BEPCII, we report the first observation of the decay $J/Ï\rightarrow K^- Σ^0…
Cross section measurement of from 4.008 GeV to 4.951 GeV
BESIII Collaboration, M. Ablikim, M. N. Achasov +682
Using data samples with a total integrated luminosity of at center-of-mass energies between 4.008 and 4.951~GeV collected with the BESIII detector, the cross sec…
