The results of the experiment searching for quarks with charge − 1 3 and 2 3 produced by 70 GeV protons on an aluminium target at zero angle are reported. For the selection of quarks the system of spectrometric scintillation counters, time-of-flight spectrometer, gas Cerenkov threshold counter and magnetic spectrometer with spark chambers were used. In the range of masses available at the IHEP accelerator, quarks were not found. The upper limit estimation of the differential cross-section for quark production with mass ⩽ 5 GeV /c 2− and charge −1 3 is 7×10 −38 cm 2 / ster GeV /c (with 90% confidence level). The total cross-section for quark production with charge −1 3 and mass 4.5–5 GeV /c 2 does not exceed 3×10 −39 cm 2 .

The result of a search for magnetic charged particles at 70 GeV IPHE proton synchrotron is presented. Using the ferromagnetic trap method the upper limit of the magnetic monopole production cross-section in proton-nucleon collisions was found to be α (95%) ⩾ × 10 −43 cm 2 .

Differential cross-sections for pp elastic scattering in the transfer momentum range 2 x 10 −3 ⩽ | t | ⩽ x 8 10 −3 (GeV/ c ) 2 were studied with a hydrogen filled ionization chamber which was used as a target and as a detector of the recoiled protons. The measurements have been done at P lab . = 1.11 GeV/ c , 1.28 GeV/ c , 1.34 GeV/ c , 1.40 GeV/ c and 1.70 GeV/ c . The real part of the spin independent forward scattering amplitude has been determined, the results being in agreement with the dispersion relation calculations.
