“…We will argue that this correction is large at low x and small Q 2 , which is precisely the region that will be probed by the EIC and similar experiments. The main goal of this letter is to demonstrate the importance of the Coulomb correction in DIS off heavy nuclei and to investigate it as a function of Q 2 , x and A. Non-negligible Coulomb corrections at medium x were recently discussed in [9].…”

We study the impact of the nuclear dependence of R = σL/σT on the extraction of the F A 2 /F D 2 and F A 1 /F D 1 structure function ratios from the data on the σ A /σ D cross section ratios. Guided by indications of the nuclear dependence of R from the world data, we examine selected sets of EMC, BCDMS, NMC and SLAC data and find thatIn particular, we observe that the nuclear enhancement (antishadowing) for F A 1 /F D 1 in the interval 0.1 < x < 0.3 becomes significantly reduced or even disappears, which indicates that antishadowing is dominated by the longitudinal structure function FL. We also argue that precise measurements of nuclear modifications of R and F A L have the potential to constrain the poorly known gluon distribution in nuclei over a wide range of x.

“…For example, at x = 0.8, the nuclear medium effects give an increase of 3% in the case of 56 F e, while it becomes 8% in the case of 208 P b. We have also studied the effect of modification in the lepton's energy and momentum due to the presence of the Coulomb field of heavy nucleus like 56 F e and 208 P b, using effective momentum approximation [52,53]. In this approximation energy of incoming and outgoing electron which is in the few GeV energy region is modified by the average nuclear Coulomb potential V 0 .…”

Recently parity violating asymmetry(AP V ) in the Deep Inelastic Scattering(DIS) of polarised electrons( e) from deuterons has been measured at JLab and there exists future plans to measure this asymmetry from nuclear targets. In view of this we study nuclear medium effects in AP V in the DIS of e from some nuclear targets like 12 C, 56 F e and 208 P b. The effects of Fermi motion, binding energy and nucleon correlations are taken into account through the nucleon spectral function calculated in a local density approximation for nuclei. The pion and rho cloud contributions have also been taken into account. This model has been earlier used to study nuclear medium effects in the electromagnetic and weak interaction induced processes. The results are presented and discussed in view of the future JLab experiments.
