Experimental and theoretical study of deuteron–proton elastic scattering for proton kinetic energies between Tp = 882.2 MeV and Tp = 918.3 MeV

New precise unpolarised differential cross sections of deuteron–proton elastic scattering have been measured at 16 different deuteron beam momenta between $p_d=3120.17\mathrm{MeV}/c$ and $p_d=3204.16\mathrm{MeV}/c$ at the COoler SYnchrotron COSY of the Forschungszentrum Jülich. The data, which were taken using the magnetic spectrometer ANKE, cover the equivalent range in proton kinetic energies from $T_p=882.2\mathrm{MeV}$ to $T_p=918.3\mathrm{MeV}$. The experimental results are analysed theoretically using the Glauber diffraction model with accurate nucleon–nucleon input. The theoretical cross section at $T_p=900\mathrm{MeV}$ agrees very well with the experimental one at low momentum transfers t. There are, however, significant deviations for $\left|t\right|>0.2{(\mathrm{GeV}/c)}^2$ that must be investigated further.
