Abstract: Exclusiveρ(770)0 photoproductionismeasured for the first time in ultraperipheral pPb collisions at√sNN = 5.02TeV with the CMS detector. The cross section σ(γp → ρ(770)0p) is 11.0 ± 1.4(stat) ± 1.0(syst) μb at Wγp = 92.6GeV for photon–proton centre-of-mass energies Wγp between 29 and 213GeV. The differential cross section dσ/d|t| is measured in the interval 0.025 < |t| < 1GeV2 asafunctionof Wγp,wheret isthesquaredfour-momentum transfer at the proton vertex. The results are compared with previousmeasurementsandtheoreticalpredictions.Themeasured cross section σ(γp → ρ(770)0p) has a power-law dependenceonthephoton–protoncentre-of-mass,consistent with electron–proton collision measurements performed at HERA. The Wγp dependence of the exponential slope of the differential cross section dσ/d|t|is also measured.
