Measurement of Born Cross Sections for $e^{+} e^{-} \to K^{+} I^^{0} I^ˉ £^{-}$ at $s = 3.51 - 4.95$ GeV and Observation of $I ¨ (3770) \to K^{+} I^^{0} I^ˉ £^{-}$

BESIII Collaboration, M. Ablikim, M. N. Achasov +771

Using 44.55 fb $^{- 1}$ of $e^{+} e^{-}$ collision data collected by the BESIII detector at the BEPCII collider, we report the first measurement of the Born cross sections for the $e^+e^-…

Precise Measurement of Matter-Antimatter Asymmetry with Entangled Hyperon Antihyperon Pairs

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

A search for $C P$ violation with an entangled system of $I^^{-} I^ˉ ^{+}$ pairs is performed, using $(10, 087 \pm 44) \times 1 0^{6}$ $J / I ¨ $ events collected with the BESIII experiment. A n…

Observation of $I^\cdot_{c} (1 S) \to I^£^{0} I^ˉ £^{0}$ and search for $h_{c} (1 P) \to I^£^{0} I^ˉ £^{0}$ via $I ¨ (3686)$ transitions

BESIII Collaboration, M. Ablikim, M. N. Achasov +776

Using $(2712.4 \pm 14.3) \times 1 0^{6} I ¨ (3686)$ events collected by the BESIII detector operating at the BEPCII collider, the hadronic decay $I^\cdot_{c} \to I^£^{0} I^£^{0} ˉ$ is observe…
