Observation of a threshold enhancement in the $I ¨ ^{+} I ¨ ^{-}$ spectrum in $I ¨ (3686) \to I ¨ ^{+} I ¨ ^{-} J / I ¨ $ decays

BESIII Collaboration, M. Ablikim, M. N. Achasov +677

The BESIII experiment analyzed over 2.7 billion ψ(3686) decays and observed a clear resonance-like enhancement near the π⁺π⁻ mass threshold in ψ(3686)→π⁺π⁻J/ψ decays, measuring its…

Observation of $Λ_{c}^{+} \to n π^{+} η$ and search for $Λ_{c}^{+} \to n a_{0} (980)^{+}$

BESIII Collaboration, M. Ablikim, M. N. Achasov +723

By analysing 6.1 $fb^{- 1}$ of data collected at center-of-mass energies between $s = 4.600$ and 4.843 $GeV$ with the BESIII detector at the BEPCII collider, we obser…

Measurement of the singly Cabibbo-suppressed decay $I^_{c}^{+} \to p I^\cdot^{'}$ with Deep Learning

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

Using $4.5$ fb $^{- 1}$ of $e^{+} e^{-}$ collision data collected with the BESIII detector at center-of-mass energies from 4.600 to 4.699 GeV, we report a measurement of the singly Cabibb…

Unraveling the structure of $I^$ hyperons with polarized $I^ I^ˉ $ pairs

The BESIII Collaboration

With data collected in a dedicated energy scan from 2.3864 up to 3.0800 GeV, the BESIII collaboration provides the first complete energy-dependent measurements of the $I^$ electrom…

Measurement of the hyperon weak radiative decay $I^^{0} \to I^^{3} I^£^{0}$ at BESIII

BESIII Collaboration, M. Ablikim, M. N. Achasov +615

The hyperon weak radiative decay $I^^{0} \to I^^{3} I^£^{0}$ is measured via the process $J / I ¨ \to I^^{0} I^ˉ ^{0}$ . The absolute branching fraction of $I^^{0} \to I^^{3} I^£^{0}$ is determined to be $(3.69\pm…

Observation of Three Resonant Structures in the Cross Section of $e^{+} e^{-} \to I ¨ ^{+} I ¨ ^{-} h_{c}$

BESIII Collaboration, M. Ablikim, M. N. Achasov +688

Using $e^{+} e^{-}$ collision data collected with the BESIII detector operating at the Beijing Electron Positron Collider, the cross section of $e^{+} e^{-} \to I ¨ ^{+} I ¨ ^{-} h_{c}$ is measured at 5…
