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…

$R (3780)$ Resonance Interpreted as the $1^{3} D_{1}$ -Wave Dominant State of Charmonium from Precise Measurements of the Cross Section of $e^{+} e^{-} \to$ Hadrons

M. Ablikim, M. N. Achasov, P. Adlarson +606

We report the precise measurements of the cross section of $e^{+} e^{-} \to$ hadrons at center-of-mass energies from 3.645 to 3.871 GeV. We thereby perform the most precise study…

Measurement of the $e^{+} e^{-} \to π^{+} π^{-}$ Cross Section between 600 and 900 MeV Using Initial State Radiation

M. Ablikim, M. N. Achasov, X. C. Ai +398

We extract the $e^{+} e^{-} \to π^{+} π^{-}$ cross section in the energy range between 600 and 900 MeV, exploiting the method of initial state radiation. A data set with an integrated…
