Abstract
An experiment to investigate the \(^{1}\)H(d, pp)n breakup reaction using a deuteron beam of 300, 340, 380 and 400 MeV and the WASA detector has been performed at the Cooler Synchrotron COSY-Jülich. As a first step the data collected at the beam energy of 340 MeV are analysed, with a focus on the proton-proton coincidences registered in the Forward Detector. The differential cross section is determined for 189 configurations on a dense angular grid defined by the emission angles of the two outgoing protons: two polar angles \(\theta _1\) and \(\theta _2\) (in the range between 5\(^{\circ }\) and 15\(^{\circ }\) with the step size of 2\(^\circ \)) and the relative azimuthal angle \(\varphi _{12}\) (in the range from 20\(^\circ \) to 180\(^\circ \), with the step size of 20\(^\circ \)).The cross section data are compared to theoretical predictions based on the state-of-the-art nucleon-nucleon potentials, combined with three-nucleon force, Coulomb interaction or carried out in a relativistic regime.
