Abstract The first measurement of the azimuthal angular correlations of exclusively produced events with two jets in photon-lead interactions at large momentum transfer is presented. Theoretical predictions relate such correlations to the polarization of gluons within nuclei. This study uses a data sample of lead-lead collisions at sNN= 5.02 TeV, corresponding to an integrated luminosity of 0.38 nb1, collected with the CMS experiment. One of the jets is required to have a transverse momentum above 30 GeV, while that of the second is greater than 20 GeV. The measured second harmonic of the correlation between the sum and difference of the two jet momenta is found to be positive, and rising, as the dijet momentum increases. The model representing the state-of-the-art calculations in electromagnetic interactions with protons overestimates this angular correlation. The measurement is also compared to a recent theoretical calculation that includes final state interactions.
