“…To conclude this Section we remark that the swelling of bound nucleons was discussed in the context of quenching of nuclear longitudinal response function in [76]. The change of confinment scale in nuclei in terms of a different approach was discussed in the context of the EMC effect in [27,77].…”

We present the results of a phenomenological study of unpolarized nuclear structure functions for a wide kinematical region of x and Q 2 . As a basis of our phenomenology we develop a model which takes into account a number of different nuclear effects including nuclear shadowing, Fermi motion and binding, nuclear pion excess and off-shell correction to bound nucleon structure functions. Within this approach we perform a statistical analysis of available data on the ratio of the nuclear structure functions F 2 for different nuclei in the range from the deuteron to the lead. We express the off-shell effect and the effective scattering amplitude describing nuclear shadowing in terms of few parameters which are common to all nuclei and have a clear physical interpretation. The parameters are then extracted from statistical analysis of data. As a result, we obtain an excellent overall agreement between our calculations and data in the entire kinematical region of x and Q 2 . We discuss a number of applications of our model which include the calculation of the deuteron structure functions, nuclear valence and sea quark distributions and nuclear structure functions for neutrino charged-current scattering. * kulagin@ms2.inr.ac.ru † Roberto.Petti@cern.ch

We have performed a many-body calculation of the longitudinal nuclear (e, e ′ ) reaction employing a Second RPA (SRPA) formalism which contains the ∆(1232). More explicitly, our scheme contains RPA correlations as well as Hartree-Fock and second order self-energies, where an accurate evaluation of exchange terms is achieved. Using this formalism we have evaluated the longitudinal response function for 40 Ca. We give final results at momentum transfers ranging from 300 up to 500 MeV/c, obtaining a good agreement with data.PACS number: 21.65+f, 25.30.Fj, 21.60.Jz.

“…CNM effects are due to the presence of ordinary nuclear matter in the collision. These include modifications to the Parton Distribution Functions (PDFs) inside a nucleus (shadowing, anti-shadowing, EMC effect) [7] and final-state nuclear absorption of J/ψ by hadronic comovers [8]. In addition, the Cronin effect, which may be originating from multiple scattering of partons, should increase the mean p T of J/ψ produced in A+A collisions relative to p+p collisions [9,10].…”

We report on the measurement of J/ψ production in the dielectron channel at mid-rapidity (|y| < 1) in p+p and d+Au collisions at √ sNN = 200 GeV from the STAR experiment at the Relativistic Heavy Ion Collider. The transverse momentum pT spectra in p+p for pT < 4 GeV/c and d+Au collisions for pT < 3 GeV/c are presented. These measurements extend the STAR coverage for J/ψ production in p+p collisions to low pT . The p 2 T from the measured J/ψ invariant cross section in p+p and d+Au collisions are evaluated and compared to similar measurements at other collision energies. The nuclear modification factor for J/ψ is extracted as a function of pT and collision centrality in d+Au and compared to model calculations using the modified nuclear Parton Distribution Function and a final-state J/ψ nuclear absorption cross section.
