Observation of the $X (2370)$ and search for the $X (2120)$ in $J / ψ \to γ K K ˉ η^{'}$

M. Ablikim, M. N. Achasov, P. Adlarson +473

Using a sample of $1.31 \times 1 0^{9} J / ψ$ events collected with the BESIII detector, we perform a study of $J / ψ \to γ K K ˉ η^{'}$ . The $X (2370)$ is observed in the $K K ˉ η^{'}$ invari…

Partial wave analysis of $ψ (3686) \to K^{+} K^{-} η$

BESIII Collaboration, M. Ablikim, M. N. Achasov +479

Using a sample of $(448.1 \pm 2.9) \times 1 0^{6}$ $ψ (3686)$ events collected with the BESIII detector, we perform the first partial wave analysis of $ψ (3686) \to K^{+} K^{-} η$ . In addi…

GKZ-hypergeometric systems for Feynman integrals

Tai-Fu Feng, Chao-Hsi Chang, Jian-Bin Chen +1

Basing on the systems of linear partial differential equations derived from Mellin-Barnes representations and Miller's transformation, we obtain GKZ-hypergeometric systems of one-l…

Observation of the decays $χ_{c J} \to ϕϕ η$

BESIII Collaboration, M. Ablikim, M. N. Achasov +481

Using a data sample of $(448.1 \pm 2.9) \times 1 0^{6}$ $ψ (3686)$ decays collected by the BESIII detector at the Beijing Electron Positron Collider (BEPCII), we observe the decays $χ_{c…

Search for baryon and lepton number violating decays $D^{+} \to Λ ˉ (Σ ˉ^{0}) e^{+}$ and $D^{+} \to Λ (Σ^{0}) e^{+}$

BESIII Collaboration, M. Ablikim, M. N. Achasov +480

Using a 2.93 fb $^{- 1}$ data sample of electron-positron collisions taken with the BESIII detector at a center-of-mass energy of 3.773 GeV, which corresponds to $(8296\pm31\pm64)\ti…
