Abstract

We report results on the total and elastic cross sections in proton-proton collisions at s=200 GeV obtained with the Roman Pot setup of the STAR experiment at the Relativistic Heavy Ion Collider (RHIC). The elastic differential cross section was measured in the squared four-momentum transfer range 0.045≤−t≤0.135 GeV². The value of the exponential slope parameter B of the elastic differential cross section dσ/dt∼e^−Bt in the measured −t range was found to be B=14.32±0.09(stat.)_−0.28^+0.13(syst.) GeV⁻². The total cross section σ_tot, obtained from extrapolation of the dσ/dt to the optical point at −t=0, is σ_tot=54.67±0.21(stat.)_−1.38^+1.28(syst.) mb. We also present the values of the elastic cross section σ_el=10.85±0.03(stat.)_−0.41^+0.49(syst.) mb, the elastic cross section integrated within the STAR t-range σ_el^det=4.05±0.01(stat.)_−0.17^+0.18(syst.) mb, and the inelastic cross section σ_inel=43.82±0.21(stat.)_−1.44^+1.37(syst.) mb. The results are compared with the world data.
