Investigations of shadowing e! For a free nucleon this leads to the following picture: prior to its interaction with the target the virtual photon uctuates into a hadronic state with invariant mass k. Here the integrals over initial and "nal hadronic uctuations and their propagators are made explicit. L LL L The next step in simpli"cation is to consider only diagonal m"n and nearest o!
An extension of this approach to nuclear targets involves multiple scattering of hadronic uctuations from several nucleons.

The multiple scattering process is described by a coupled channel optical model [,] which accounts for the shadowing criteria in Eq. Vector mesons and quark scattering We add a few remarks and references about approaches dealing with DIS in terms of quark dynamics. The starting point in Ref. O, 58 G.

An extraction of the pion structure function at small x from semi-exclusive reactions at HERA has been discussed recently in [,].
The resulting pionic correction dppH to double scattering turns out to be positive, i. The relative weight of dppH decreases with decreasing x. Interpretation of nuclear shadowing in the inxnite momentum frame In this section we brie y discuss how nuclear shadowing develops in the in"nite momentum frame where the parton model for deep-inelastic scattering can be applied.
