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…
