Cross sections for pentaquark baryon production from protons in reactions induced by hadrons and photons
Cross sections for pentaquark baryon production from protons in reactions induced by hadrons and photons
Using hadronic Lagrangians that include the interaction of pentaquark ${\ensuremath{\Theta}}^{+}$ baryon with $K$ and $N$, we evaluate the cross sections for its production from meson-proton, proton-proton, and photon-proton reactions near threshold. With empirical coupling constants and form factors, the predicted cross sections are about $1.5\phantom{\rule{0.3em}{0ex}}\text{mb}$ in kaon-proton reactions, $0.1\phantom{\rule{0.3em}{0ex}}\text{mb}$ in …
