Differential cross sections for the reactions γp→pη and γp→pη'

<p>High-statistics differential cross sections for the reactions γp→pη and γp→pη^' have been measured using the CEBAF large acceptance spectrometer (CLAS) at Jefferson Lab for center-of-mass energies from near threshold up to 2.84 GeV. The η^' results are the most precise to date and provide the largest energy and angular coverage. The η measurements extend the energy range of the world’s large-angle results by approximately 300 MeV. These new data, in particular the η^' measurements, are likely to help constrain the analyses being performed to search for new baryon resonance states.</p>
