$R (3780)$ Resonance Interpreted as the $1^{3} D_{1}$ -Wave Dominant State of Charmonium from Precise Measurements of the Cross Section of $e^{+} e^{-} \to$ Hadrons

M. Ablikim, M. N. Achasov, P. Adlarson +606

We report the precise measurements of the cross section of $e^{+} e^{-} \to$ hadrons at center-of-mass energies from 3.645 to 3.871 GeV. We thereby perform the most precise study…

Measurement of $I^£^{+}$ transverse polarization in $e^{+} e^{-}$ collisions at $s = 3.68 - 3.71$ GeV

BESIII Collaboration, M. Ablikim, M. N. Achasov +645

Using $e^{+} e^{-}$ collision data collected with the BESIII detector at seven energy points ranging from 3.68 to 3.71 GeV and corresponding to an integrated luminosity of $652.1~{\rm p…

Search for $h_{c} \to I ¨ ^{+} I ¨ ^{-} J / I ¨ $ via $I ¨ (3686) \to I ¨ ^{0} h_{c}$

BESIII Collaboration, M. Ablikim, M. N. Achasov +657

Using $(2712.4 \pm 14.3) \times 1 0^{6} I ¨ $ (3686) events collected with the BESIII detector operating at the BEPCII collider, we search for the hadronic transition $h_c \to Ï^+Ï^-J/…

LHAASO detection of very-high-energy gamma-ray emission surrounding PSR J0248+6021

Zhen Cao, F. Aharonian, Q. An +276

We report the detection of an extended very-high-energy (VHE) gamma-ray source coincident with the location of middle-aged (62.4~\rm kyr) pulsar PSR J0248+6021, by using the LHAASO…

Search for lepton number violating decays of $D_{s}^{+} \to h^{-} h^{0} e^{+} e^{+}$

BESIII Collaboration, M. Ablikim, M. N. Achasov +655

Based on 7.33 fb $^{- 1}$ of $e^{+} e^{-}$ collision data collected by the BESIII detector operating at the BEPCII collider at center-of-mass energies from 4.128 to 4.226 GeV, a search fo…

Model-independent determination of the strong-phase difference between $D^{0}$ and $D ˉ^{0} \to I ¨ ^{+} I ¨ ^{-} I ¨ ^{+} I ¨ ^{-}$ decays

BESIII Collaboration, M. Ablikim, M. N. Achasov +652

Measurements of the strong-phase difference between $D^{0}$ and $D ˉ^{0} \to I ¨ ^{+} I ¨ ^{-} I ¨ ^{+} I ¨ ^{-}$ are performed in bins of phase space. The study exploits a sample of quantum-correlated…
