Seedance 1.5 pro: A Native Audio-Visual Joint Generation Foundation Model

Team Seedance, Heyi Chen, Siyan Chen +194

Recent strides in video generation have paved the way for unified audio-visual generation. In this work, we present Seedance 1.5 pro, a foundational model engineered specifically f…

Model-independent determination of the strong-phase difference between $D^{0}$ and $D ˉ^{0} \to π^{+} π^{-} π^{+} π^{-}$ decays

BESIII Collaboration, M. Ablikim, M. N. Achasov +652

Measurements of the strong-phase difference between $D^{0}$ and $D ˉ^{0} \to π^{+} π^{-} π^{+} π^{-}$ are performed in bins of phase space. The study exploits a sample of quantum-correlated $D\…

Measurement of the $C P$ -even fraction of $D^{0} \to K^{+} K^{-} π^{+} π^{-}$

BESIII Collaboration, M. Ablikim, M. N. Achasov +571

A determination of the $C P$ -even fraction $F_{+}$ in the decay $D^{0} \to K^{+} K^{-} π^{+} π^{-}$ is presented. Using $2.93$ fb $^{- 1}$ of $e^{+} e^{-} \to ψ (3770) \to D D ˉ$ data collected by the B…

Observation of the double Dalitz decay $η^{'} \to e^{+} e^{-} e^{+} e^{-}$

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

Based on $(10087 \pm 44) \times 1 0^{6}$ $J / ψ$ events collected with the BESIII detector at BEPCII, the double Dalitz decay $η^{'} \to e^{+} e^{-} e^{+} e^{-}$ is observed for the first time via the $…
