abstract = {For the first time at LHC energies, the forward rapidity
gap spectra from proton-lead collisions for both proton and
lead dissociation processes are presented. The analysis is
performed over 10.4 units of pseudorapidity at a
center-of-mass energy per nucleon pair of
$\sqrt{s_\mathrm{NN}}$ = 8.16 TeV, almost 300 times higher
than in previous measurements of diffractive production in
proton-nucleus collisions. For lead dissociation processes,
which correspond to the pomeron-lead event topology, the
EPOS-LHC generator predictions are a factor of two below the
data, but the model gives a reasonable description of the
rapidity gap spectrum shape. For the pomeron-proton
topology, the EPOS-LHC, QGSJET II, and HIJING predictions
are all at least a factor of five lower than the data. The
latter effect might be explained by a significant
contribution of ultra-peripheral photoproduction events
mimicking the signature of diffractive processes. These data
may be of significant help in understanding the high energy
limit of quantum chromodynamics and for modeling cosmic ray
air showers.},
