Forward \(\pi^\circ\) production and associated transverse energy flow in deep-inelastic scattering at HERA

experimental physics


Deep-inelastic positron-proton interactions at low values of Bjorken-x down to \(x \approx 4\cdot 10^{-5}\) which give rise to high transverse momentum \(\pi^\circ\)-mesons are studied with the H1 experiment at HERA. The inclusive cross section for \(\pi^\circ\)-mesons produced at small angles with respect to the proton remnant (the forward region) is presented as a function of the transverse momentum and energy of the \(\pi^\circ\) and of the four-momentum transfer Q2 and Bjorken-x. Measurements are also presented of the transverse energy flow in events containing a forward \(\pi^\circ\)-meson. Hadronic final state calculations based on QCD models implementing different parton evolution schemes are confronted with the data.
