The reactions e − p → ∆ 0 ν e and e + p → ∆ ++ ¯ ν e are considered as a possible source of information about the weak N∆ transition form factors. The low q 2 BNL data on ν µ production of ∆ are used to extract the axial vector N∆ coupling, taking into account the deuteron structure and the ∆ width. Finally, pion production induced by neutrinos in 16 O in the ∆ region, relevant to atmospheric ν...

We study the disintegration of nuclei by strong electromagnetic fields induced by ultrarelativistic heavy ions. The proposed multi-step model includes 1) the absorption of a virtual photon by a nucleus, 2) intranuclear cascades of produced hadrons and 3) statistical decay of the excited residual nucleus. The combined model describes well existing data on projectile fragmentation at energy 200 G...

Dilepton production following radiative capture of a proton on a nuclear target is studied in the Impulse Approximation. The cross section is decomposed in terms of four time-like nuclear structure functions through a longitudinal-transverse separation of the nuclear current. Using a simple PWIA model, cross sections and conversion factors are calculated for capture at proton energies of 100-20...
