  The current normalization of the cross section of inclusive high-pT particle
production in deuteron-gold collisions measured RHIC relies on Glauber
calculations for the inelastic d-Au cross section. These calculations should be
corrected for diffraction. Moreover, they miss the Gribov's inelastic shadowing
which makes nuclei more transparent (color transparency). The magnitude of this
effect rises with energy and it may dramatically affect the normalization of
the RHIC data. We evaluate these corrections employing the light-cone dipole
formalism and found a rather modest corrections for the current normalization
of the d-Au data. The results of experiments insensitive to diffraction
(PHENIX, PHOBOS) should be renormalized by about 20% down, while those which
include diffraction (STAR), by only 10%. Such a correction completely
eliminates the Cronin enhancement in the PHENIX data for pions. The largest
theoretical uncertainty comes from the part of the inelastic shadowing which is
related to diffractive gluon radiation, or gluon shadowing. Our estimate is
adjusted to data for the triple-Pomeron coupling, however, other models do not
have such a restrictions and predict much stronger gluon shadowing. Therefore,
the current data for high-pT hadron production in d-Au collisions at RHIC
cannot exclude in a model independent way the possibility if initial state
suppression proposed by Kharzeev-Levin-McLerran. Probably the only way to
settle this uncertainty is a direct measurement of the inelastic d-Au cross
sections at RHIC. Also d-Au collisions with a tagged spectator nucleon may
serve as a sensitive probe for nuclear transparency and inelastic shadowing. We
found an illuminating quantum-mechanical effect: the nucleus acts like a lens
focusing spectators into a very narrow cone.
