“…The results are consistent with those obtained in Ref. [26], even including the heavy quark contribution, showing that the Coulomb correction is quite important in the kinematical region of low-Q 2 and small-x and it is enhanced for the heavier nuclei. In the perturbative range that will be probed in the future EIC (Q 2 > ∼ 1 GeV 2 ) and A = 197, the Coulomb contribution is ≈ 10 (21)% for the inclusive (diffractive) cross section.…”

“…In Refs. [26,35,36], the Glauber model has been applied to describe the dipole -nucleus interaction and the additivity of the strong and Coulomb phase shifts to estimate the dipole -nucleon was assumed. As a consequence, the dipole -nucleus forward scattering amplitude can be expressed as follows [26,36]…”

“…A first analysis of the impact of these corrections to the DIS off a heavy nucleus has been performed in Ref. [26] (See also Ref. [27]) and has indicated that the Coulomb corrections reach to 20 % of the inclusive cross section and about 40% of the diffractive cross section in the kinematical range of small values of the Bjorken-x variable and low photon virtualities Q 2 .…”

The experimental results of the future electron -ion (eA) collider are expected to constrain the dynamics of the strong interactions at small values of the Bjorken -x variable and large nuclei.Recently it has been suggested that Coulomb corrections can be important in inclusive and diffractive eA interactions. In this paper we present a detailed investigation of the impact of the Coulomb corrections to some of the observables that will be measured in the future eA collider. In particular, we estimate the magnitude of these corrections for the charm and longitudinal cross sections in inclusive and diffractive interactions. Our results demonstrate that the Coulomb corrections for these observables are negligible, which implies that they can be used to probe the QCD dynamics.PACS numbers:

An essential part of experimental program at the future Electron Ion Collider is the study of the nuclear structure and dynamics at low x. DIS at low x is characterized by large longitudinal coherence length that by far exceeds radii of heavy nuclei. The coherent behavior is essential feature of the nuclear matter at low x. This pertains not only to the strong interactions, but also to electromagnetic ones. Coherent interactions of a projectile with nucleons in a heavy nucleus are characterized by parameters α 2 s A 1/3 ∼ 1 and αZ ∼ 1 in strong and electromagnetic interactions respectively. Contributions exhibiting non-trivial dependence on αZ are called the Coulomb corrections. We compute the Coulomb corrections to the cross sections of the semi-inclusive and diffractive DIS. We show that they violate the geometric scaling in a wide range of photon virtualities and is weakly x-independent. In heavy nuclei at low Q 2 the Coulomb correction to the total and diffractive cross sections is about 20% and 40% correspondingly. Coulomb corrections to DIS off heavy nuclei Kirill Tuchin Nuclear dependence of the dipole cross sectionσ .At high energies, interaction of the projectile proton with different nucleons is independent inasmuch as the nucleons do not overlap in the longitudinal direction. This assumption is tantamount to taking into account only two-body interactions, while neglecting the many-body ones [5]. 1 The relationship between the cross section σ = σ T + σ L and F 1 , F 2 structure functions is non-trivial due to large Coulomb corrections to the leptonic tensor [4].
