Search for a massless particle beyond the Standard Model in the $Ξ^{0} \to Λ + invisible$ decay

BESIII Collaboration, M. Ablikim, M. N. Achasov +770

A search for a massless beyond-standard-model particle is performed in the decay $Ξ^{0} \to Λ + invisible$ using $(1.0087 \pm 0.0044) \times 1 0^{10}$ $J / ψ$ events collected with…

Measurement of Born Cross Sections and Effective Form Factors of $e^{+} e^{-} \to I^c ◯^{-} I^ˉ c ◯^{+}$ from $s$ = 3.7 to 4.7 GeV

BESIII Collaboration, M. Ablikim, M. N. Achasov +635

Using $e^{+} e^{-}$ collision data corresponding to an integrated luminosity of 22.7 fb $^{- 1}$ , collected at center-of-mass energies between 3.7 and 4.7 GeV with the BESIII detector at…
