Search for the charged lepton flavour violating decay $η^{'} \to e μ$

BESIII Collaboration, M. Ablikim, M. N. Achasov +765

Based on $(8998 \pm 40) \times 1 0^{6}$ $J / ψ$ events collected in $e^{+} e^{-}$ collisions at $s = 3.097$ GeV with the BESIII detector, we present a search for the charged lepton flavou…

Proof of principle for nucleon polarization measurement at BESIII

BESIII Collaboration, M. Ablikim, M. N. Achasov +754

A novel technique for measuring the spin polarization of final-state nucleons in a general-purpose spectrometer is validated. Using $10.09 \times 1 0^{9}$ $J / I ¨ $ events at BESIII, the…

Study of the $e^{+} e^{-} \to I ¨ ^{+} I ¨ ^{-} D_{s}^{+} D_{s}^{-}$ process from $s$ = 4.42 to 4.95 GeV at BESIII

BESIII Collaboration, M. Ablikim, M. N. Achasov +782

Based on $8.5 fb^{- 1}$ of $e^{+} e^{-}$ collision data collected at center-of-mass energies between 4.42 and 4.95 GeV with the BESIII detector at the BEPCII storage ring, we inves…

Exotic hadrons associated with $b$ -quark

Xinchen Dai, Sen Jia, Alexey Nefediev +3

Compared to charmonium-like states, exotic hadrons associated with $b$ -quark offer distinct advantages for exploring the nature of multiquark phenomena and the dynamics of the stro…

Precision Measurement of $D_{s}^{*+}$ - $D_{s}^{+}$ Mass Difference

BESIII Collaboration, M. Ablikim, M. N. Achasov +684

The paper reports a precise measurement of the mass difference between the charm-strange mesons D_s*+ and D_s+ using e⁺e⁻ collision data collected by the BESIII detector.

Observation of a New Excited $I^£$ State in $I ¨ (3686) \to p ˉ K^{+} I^£^{0} + c . c .$

BESIII Collaboration, M. Ablikim, M. N. Achasov +681

Using a data sample of $(2712.4 \pm 14.3) \times 1 0^{6} I ¨ (3686)$ events collected with the BESIII detector, a partial-wave analysis of $I ¨ (3686) \to p ˉ K^{+} I^£^{0} + c . c .$ is performed. A…
