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…

First Measurement of the Absolute Branching Fraction of $I^\cdot_{c} \to I^^{3} I^^{3}$

BESIII Collaboration, M. Ablikim, M. N. Achasov +691

We apply a tag-and-probe method to precisely measure the absolute branching fraction of the decay $I^\cdot_{c} \to I^^{3} I^^{3}$ with the BESIII experiment at BEPCII. Starting with a large initia…
