Two classes of constacyclic codes with a square-root-like lower bound

Tingfang Chen, Zhonghua Sun, Conghui Xie +2

Constacyclic codes over finite fields are an important class of linear codes as they contain distance-optimal codes and linear codes with best known parameters. They are interestin…

Observation of $D \to a_{0} (980) π$ in the decays $D^{0} \to π^{+} π^{-} η$ and $D^{+} \to π^{+} π^{0} η$

BESIII Collaboration, M. Ablikim, M. N. Achasov +640

We report the first amplitude analysis of the decays $D^{0} \to π^{+} π^{-} η$ and $D^{+} \to π^{+} π^{0} η$ using a data sample taken with the BESIII detector at the center-…

Search for $Δ S = 2$ nonleptonic hyperon decays $Ω^{-} \to Σ^{0} π^{-}$ and $Ω^{-} \to n K^{-}$

BESIII Collaboration, M. Ablikim, M. N. Achasov +644

Using $(27.12 \pm 0.14) \times 1 0^{8}$ $ψ (3686)$ events collected by the BESIII detector at the center-of-mass energy of $s = 3.686$ GeV, we search for the first time for tw…

Evidence of the $h_{c} \to K_{S}^{0} K^{+} π^{-} + c . c .$ decay

BESIII Collaboration, M. Ablikim, M. N. Achasov +644

Based on $(2.712 \pm 0.014) \times 1 0^{9}$ $ψ (3686)$ events collected by the BESIII collaboration, evidence of the hadronic decay $h_{c} \to K_{S}^{0} K^{+} π^{-} + c . c .$ is found with a significance o…

Search for the production of deuterons and antideuterons in e^+e^- annihilation at center-of-mass energies between 4.13 and 4.70 GeV

BESIII Collaboration, M. Ablikim, M. N. Achasov +603

Using a data sample of $e^{+} e^{-}$ collision data corresponding to an integrated luminosity of 19 fb $^{- 1}$ collected with the BESIII detector at the BEPCII collider, we search for th…

Measurement of the Electromagnetic Transition Form-factors in the decays $η^{'} \to π^{+} π^{-} l^{+} l^{-}$

BESIII Collaboration, M. Ablikim, M. N. Achasov +628

With a sample of $(10087 \pm 44) \times 1 0^{6}$ $J / ψ$ events accumulated with the BESIII detector, we analyze the decays $η^{'} \to π^{+} π^{-} l^{+} l^{-} (l = e,$ $μ)$ via the process $J/ψ\righ…
