dc.description.abstract | Exclusive ρ(770) 0 photoproduction is measured for the first time in ultraperipheral pPb collisions at √ s NN = 5.02 TeV with the CMS detector. The cross section σ(γp → ρ(770) 0p) is 11.0 ± 1.4 (stat) ± 1.0 (syst) μb at Wγ p = 92.6GeV for photon–proton centre-of-mass energies Wγ p between 29 and 213 GeV. The differential cross section dσ/d|t| is measured in the interval 0.025 < |t| < 1GeV2 as a function of Wγ p , where t is the squared four-momentum transfer at the proton vertex. The results are compared with previous measurements and theoretical predictions.The measured cross section σ(γp → ρ(770) 0p) has a power-law dependence on the photon–proton centre-of-mass, consistent with electron–proton collision measurements performed at HERA. The Wγ p dependence of the exponential slope of the differential cross section dσ/d|t| is also measured. | en_US |
