General Laboratory Seminar by V.S. Kurbatov, 12 September 2018

The results in the form of differential cross sections were analyzed together with those earlier obtained by the collaboration. The energy dependence of the cross section for the range of 0◦ < θpp?≤ 18◦ has a distinct peak at the beam energies in the interval of 1.5–2.2 GeV. In addition, the differential cross section increases in this interval on approaching the zero angle in contrast to situation at all other energies beyond this interval. This may indicate that in this energy region dynamics of the process is radically different from that at other energies. The mass and width of the peak obtained by fitting within the simplest isobaric model may correspond to the excitation of ∆(1620) in the intermediate state. See the full version of the seminar here.
