Observation of the decay $ψ (3686) \to Σ^{0} Σ ˉ^{0} ω$

BESIII Collaboration, M. Ablikim, M. N. Achasov +689

Using a dataset of $(27.12 \pm 0.14) \times 1 0^{8}$ $ψ (3686)$ events collected by the BESIII detector operating at the BEPCII collider, we report the first observation of the decay $…

Improved measurements of $D^{0} \to K^{-} ℓ^{+} ν_{ℓ}$ and $D^{+} \to K ˉ^{0} ℓ^{+} ν_{ℓ}$

BESIII Collaboration

Using 7.93 fb $^{- 1}$ of $e^{+} e^{-}$ collision data collected at the center-of-mass energy of 3.773 GeV with the BESIII detector, we measure the absolute branching fractions of $D^0\to…

Cross section measurement of $e^{+} e^{-} \to η ψ (2 S)$ and search for $e^{+} e^{-} \to η X ~ (3872)$

BESIII Collaboration, M. Ablikim, M. N. Achasov +645

The energy-dependent cross section for $e^{+} e^{-} \to η ψ (2 S)$ is measured at eighteen center of mass energies from 4.288 GeV to 4.951 GeV using the BESIII detector. Using the same data…

Precision Measurement of the Mass of the $τ$ Lepton

M. Ablikim, M. N. Achasov, X. C. Ai +374

An energy scan near the $τ$ pair production threshold has been performed using the BESIII detector. About $24$ pb $^{- 1}$ of data, distributed over four scan points, was collected.…
