Evidence of $I ¨ (3770) \to I ¨ ^{0} J / I ¨ $

BESIII Collaboration, M. Ablikim, M. N. Achasov +766

We report the first evidence for the hadronic transition $I ¨ (3770) \to I ¨ ^{0} J / I ¨ $ using a data sample of $20.3 fb^{- 1}$ collected at $s = 3.773$ ~GeV with the BESIII…

Optimal binning of $D \to K_{S}^{0} I ¨ ^{+} I ¨ ^{-}$ and $D \to K_{S}^{0} K^{+} K^{-}$ phase space for experimental measurements

Marcelo Bovill, Nathan Jurik, Sneha Malde

New binning schemes for the Dalitz plots of $D \to K_{S}^{0} I ¨ ^{+} I ¨ ^{-}$ and $D \to K_{S}^{0} K^{+} K^{-}$ decays are presented. These are determined using a n…

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…

Helicity amplitude and branching fraction measurement of $I ¨ _{c J} \to I^ I^ˉ $

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

Utilizing $2712.4 \pm 14.3$ million $I ¨ (3686)$ events accumulated by the BESIII experiment, we perform a partial wave analysis of $Ï(3686)\rightarrowÎ³Ï_{cJ}\rightarrowÎ³Î\barÎ…

First observation of $I^_{c} (2595)^{+} \to I^_{c}^{+} I ¨ ^{0} I ¨ ^{0}$ and $I^_{c} (2625)^{+} \to I^_{c}^{+} I ¨ ^{0} I ¨ ^{0}$

BESIII Collaboration, M. Ablikim, M. N. Achasov +658

By analysing $e^{+} e^{-}$ annihilation data corresponding to an integrated luminosity of 368.48~pb $^{- 1}$ collected at the centre-of-mass energies of $s = 4.918$ and $4.951$ ~GeV…
