Description
Short-Range Correlations (SRC) are specific type of local density fluctuations within nucleus formed by two nucleons coming as close to each other as a nucleon radius. At this moment the momenta of both paired nucleons are opposite and higher than the Fermi momentum. In JINR the second SRC experiment at BM@N took data in 2022. The hard quasi-free scattering reactions 12C(p, 2p)11B/10B/10Be were reconstructed in inverse kinematics implying a 37 GeV/c carbon beam and a liquid hydrogen target. The final state ions traveling along the beam direction pass through the magnetic spectrometer and were measured. The listed final state ions correspond to a knockout of a single proton or a pn- or pp-SRC pair from the 12C nucleus. After that the fragmentation pattern for quasi-elastic and SRC events will be studied. The analysis has been started with the improved calibration of the time-of-flight detector and reconstruction of the straight tracks upstream the magnet.
