Aspects of near threshold neutral pion photoproduction off protons
We investigate near threshold neutral pion photoproduction off protons to fourth order in heavy baryon chiral perturbation theory in the light of the new data from MAMI. We show that the unitarity cusp at the secondary πn threshold is in agreement with expectations from the final state theorem. We also analyze the fourth order corrections to the P–wave low–energy theorems and show that potentia...

متن کاملPrimakoff effect in η-photoproduction off protons
We analyse data on forward η-meson photoproduction off a proton target and extract the η→γγ decay width utilizing the Primakoff effect. The hadronic amplitude that enters into our analysis is strongly constrained because it is fixed from a global fit to available γp→pη data for differential cross sections and polarizations. We compare our results with present information on the two-photon η-dec...
متن کاملDependence of Net – protons at √ s NN = 200 GeV
The BRAHMS collaboration has measured inclusive proton and anti–proton spectra at several rapidities (0 ≤ y ≤ 3) for Au+Au collisions at √ s N N = 200 GeV. Rapidity densities of protons, anti–protons, and net–protons [N(p) − N(¯ p)] are presented as a function of rapidity.
