Abstract: (APS)

The total cross sections of π± on protons in the momentum interval 2 to 7 GeV/c have been measured with high precision. The error fluctuations from point to point vary between 10 and 25 μb. Two new pion-nucleon resonances, one in each of the two isotopic states, have been found at the following mass values: M12=2.65±0.01 GeV and M32=2.85±0.01 GeV. A search for other resonances at higher momenta is discussed.
