Broadband $γ$ -ray spectrum of supernova remnant Cassiopeia A

Zhen Cao, F. Aharonian, Y. X. Bai +311

The core-collapse supernova remnant (SNR) Cassiopeia A (Cas A) is one of the brightest galactic radio sources with an angular radius of $\sim$ 2.5 $\arcmin$. Although no extension…

Cross section measurement of $e^{+} e^{-} \to f_{1} (1285) π^{+} π^{-}$ at center-of-mass energies between $3.808$ and $4.951 GeV$

BESIII Collaboration, M. Ablikim, M. N. Achasov +644

Using data samples collected by the \mbox{BESIII} detector located at the Beijing Electron Positron Collider, the cross sections of the process $e^{+} e^{-} \to f_{1} (1285) π^{+} π^{-}$ are me…

Search for the leptonic decay $D^{+} \to e^{+} ν_{e}$

BESIII Collaboration, M. Ablikim, M. N. Achasov +651

We search for the leptonic decay $D^{+} \to e^{+} ν_{e}$ using an $e^{+} e^{-}$ collision data sample with an integrated luminosity of 20.3~fb $^{- 1}$ collected with the BESIII detector at the…

Observation of $ψ (3686) \to K^{-} Λ (1520) Ξ ˉ^{+} + c . c .$

BESIII Collaboration, M. Ablikim, M. N. Achasov +650

Based on $(2712.4 \pm 14.3) \times 1 0^{6}$ $ψ (3686)$ events collected at the BESIII detector operating at the BEPCII collider, we present the first observation of the decay $ψ(3686) \…
