Results on total and elastic cross sections in proton-proton collisions at root s=200 GeV

Popis výsledku v původním jazyce

We report results on the total and elastic cross sections in proton-proton collisions at root 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 d sigma/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 stot, obtained from extrapolation of the ds/dt to the optical point at -t = 0, is d(tot) = 54.67 +/- 0.21(stat.)(-1.38)(+1.28)(syst.) mb. We also present the values of the elastic cross section sigma(el) = 10.85 +/- 0.03(stat.)(-0.41)(+0.49()syst.) mb, the elastic cross section integrated within the STAR t-range sigma(det)(el) = 4.05 +/- 0.01(stat.)-(+0.18)(0.17)(syst.) mb, and the inelastic cross section sigma(inel) = 43.82 +/- 0.21(stat.)(-1.44)(+1.37) (syst.) mb. The results are compared with the world data.
