Measurement of Born cross sections for $e^{+} e^{-} \to p p ˉ$ at $s = 3.510 - 4.946$ GeV

BESIII Collaboration, M. Ablikim, M. N. Achasov +758

We report a measurement of the Born cross section and the effective form factor for the $e^{+} e^{-} \to p p ˉ$ reaction at 47 center-of-mass energies between 3.510 and 4.946 GeV. The…

Observation of $I ¨ (3770) \to p p ˉ$ and Measurement of Electromagnetic Form Factors of Proton at $s = 3.510 - 4.946$ GeV

BESIII Collaboration, M. Ablikim, M. N. Achasov +758

We search for possible charmonium(-like) states decaying into the $p p ˉ$ final state by studying the Born cross sections of the $e^{+} e^{-} \to p p ˉ$ reaction, and we determine…

Search for the charmonium weak decay $I ¨ (2 S) \to D_{s}^{-} I ¨ ^{+} + c . c .$ and $I ¨ (2 S) \to D_{s}^{-} I ¨ ^{+} + c . c .$

BESIII Collaboration, M. Ablikim, M. N. Achasov +720

We search for the weak decays $I ¨ (2 S) \to D_{s}^{-} I ¨ ^{+} + c . c .$ and $I ¨ (2 S) \to D_{s}^{-} I ¨ ^{+} + c . c .$ for the first time. The search is based on $(2712.4 \pm 14.3) \times 1 0^{6}$ events containin…

Cross Section Measurements of $n ˉ p \to K^{+} K^{-} I ¨ ^{+} (I ¨ ^{0})$ via Antineutrons Produced by $J / I ¨ \to p I ¨ ^{-} n ˉ$ Decays

BESIII Collaboration, M. Ablikim, M. N. Achasov +759

Based on a novel method for producing antineutrons via $J / I ¨ $ decays, we report a study of $n ˉ p$ inelastic scattering into final states containing kaons. The analysis uses $(1…
