Measurement of exclusive rho(770)(0) photoproduction in ultraperipheral pPb collisions at root s(NN)=5.02 TeV
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) 0 p) is 11.0 ± 1.4 (stat) ± 1.0 (syst) μb at �Wγ p � = 92.6 GeV for photon–proton centre-of-mass energies Wγ p betw...

| description | 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)
0
p) is 11.0 ± 1.4 (stat) ± 1.0 (syst) μb at �Wγ p � =
92.6 GeV 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| < 1 GeV2
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)
0
p) 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 |
