Study of $I^\cdot \to I ¨ ^{+} I ¨ ^{-} l^{+} l^{-}$

BESIII Collaboration, M. Ablikim, M. N. Achasov +639

Using a sample of $(10087 \pm 44) \times 1 0^{6}$ $J / I ¨ $ events accumulated with the BESIII detector, we analyze the decays $I^\cdot \to I ¨ ^{+} I ¨ ^{-} l^{+} l^{-}$ ( $l = e$ or $I^¼$ ) via the process…

Search for $e^{+} e^{-} \to K_{S}^{0} K_{S}^{0} h_{c}$

BESIII Collaboration, M. Ablikim, M. N. Achasov +650

Using $e^{+} e^{-}$ collision data at 13 center-of-mass energies ranging from 4.600 to 4.950 GeV collected with the BESIII detector, we search for the unmeasured $e^+e^-\to K_S^0 K_S^0…

Search for a $1^{-+}$ molecular state via $e^{+} e^{-} \to I^^{3} D_{s}^{+} D_{s 1}^{-} (2536) + c . c .$

BESIII Collaboration, M. Ablikim, M. N. Achasov +651

We search, for the first time, for an exotic molecular state with quantum numbers $J^{P C} = 1^{-+}$ , called $X$ , via the process $e^{+} e^{-} \to I^^{3} D_{s}^{+} D_{s 1}^{-} (2536) + c . c .$ u…

Measurement of cross sections of $e^{+} e^{-} \to K_{S}^{0} K_{S}^{0} I ¨ (3686)$ from $s =$ 4.682 to 4.951 GeV

BESIII Collaboration, M. Ablikim, M. N. Achasov +650

The process $e^{+} e^{-} \to K_{S}^{0} K_{S}^{0} I ¨ (3686)$ is studied by analyzing $e^{+} e^{-}$ collision data samples collected at eight center-of-mass energies ranging from 4.682 to 4.951 GeV with…

Measurement of the Decay $I^^{0} \to I^ I^^{3}$ with Entangled $I^^{0} I^ˉ ^{0}$ Pairs

BESIII Collaboration, M. Ablikim, M. N. Achasov +643

In this Letter, a systematic study of the weak radiative hyperon decay $I^^{0} \to I^ I^^{3}$ at an electron-positron collider using entangled $I^^{0} I^ˉ ^{0}$ pair events is presented.…
