Abstract:

Based on the previous approach, we have investigated a possibility to resolve the discrepancy between the E710, E811 and CDF at √s = 1.8 TeV, using the experimental data of the pp, pp total cross sections σ _tot⁽⁺⁾ and ρ⁽⁺⁾ ratio up to the SPS experiments (√s = 0.9 TeV) as inputs. We predict σ _tot^pp and ρ^pp at the Tevatron energy (√s = 1.8 TeV) as σ _tot^pp = 75.9 ±1.0 mb, ρ^pp = 0.136 ±0.005.
It turns out that only the data of E710 is consistent with the prediction in the one standard deviation. So we can conclude that E710 is preferable but we can exclude neither CDF nor E811 results.
