Proton and kaon timelike form factors from BABAR
S. I. Serednyakov
TL;DR
This paper presents recent BABAR measurements of proton and kaon timelike form factors, comparing them with spacelike counterparts and analyzing the cross section behavior near the nucleon-antinucleon threshold.
Contribution
It provides new experimental data on timelike form factors and discusses their relation to spacelike form factors and threshold phenomena.
Findings
Proton form factors rise near the threshold.
Comparison shows differences between spacelike and timelike form factors.
Cross section behavior near threshold is characterized.
Abstract
The latest BABAR results on the proton and kaon timelike form factors (FF) are presented. The special emphasize is made on comparison of the spacelike and timelike FFs and the rise of the proton FF near threshold. The behavior of the cross section of e+e- annihilation into hadrons near the nucleon-antinucleon threshold is discussed.
