Study of the decay $D^{0} \to ρ (770)^{-} e^{+} ν_{e}$

BESIII Collaboration, M. Ablikim, M. N. Achasov +651

We present a study of the semileptonic decay $D^{0} \to π^{-} π^{0} e^{+} ν_{e}$ using an $e^{+} e^{-}$ annihilation data sample of $7.93 fb^{- 1}$ collected at the center-of-mass…

Measurement of the Branching Fraction of \boldmath{ $ψ (2 S) \to γ π^{0}$ }

BESIII Collaboration, M. Ablikim, M. N. Achasov +650

Based on $(2712.4 \pm 14.1) \times 1 0^{6} ψ (2 S)$ events, 7.9 fb $^{- 1}$ $ψ (3773)$ data, and 0.8 fb $^{- 1}$ off-resonance data samples collected with the BESIII detector, we measure the b…

Measurement of the $e^{+} e^{-} \to K^{+} K^{-} ψ (2 S)$ Cross Section at Center-of-Mass Energies from 4.699 to 4.951 GeV and Search for $Z_{cs}^{\pm}$ in the $Z_{cs}^{\pm} \to K^{\pm} ψ (2 S)$ Decay

BESIII Collaboration, M. Ablikim, M. N. Achasov +651

We perform the first investigation of the process $e^{+} e^{-} \to K^{+} K^{-} ψ (2 S)$ and report its Born cross sections over a range of center-of-mass energies from 4.699 to 4.951~GeV. Th…

Measurement of the $e^{+} e^{-} \to π^{+} π^{-} J / ψ$ cross section in the vicinity of 3.872 GeV

BESIII Collaboration, M. Ablikim, M. N. Achasov +566

We report a measurement of the cross section for the process $e^{+} e^{-} \to π^{+} π^{-} J / ψ$ around the $X (3872)$ mass in search for the direct formation of $e^{+} e^{-} \to X (3872)$ through the tw…

Measurement of the total and leptonic decay widths of the $J / ψ$ resonance with an energy scan method at BESIII

BESIII Collaboration, M. Ablikim, M. N. Achasov +566

Using $e^{+} e^{-}$ annihilation data sets collected with the BESIII detector, we measure the cross sections of the processes $e^{+} e^{-} \to e^{+} e^{-}$ and $e^{+} e^{-} \to μ^{+} μ^{-}$ at fifteen cent…
