Abstract
Electromagnetic interactions of heavy-ions give access to a unique programme of photon-induced studies in the QCD and QED sectors of the Standard Model. On the one hand, exclusive photoproduction of bottomonium (γA→ϒA, where the nucleus A remains intact) offers a useful means to constrain the small-x nuclear gluon density. On the other, two-photon exclusive dilepton production (γγ→l+l−) allows us to study QED at fieldstrengths close or above the Schwinger limit (Ecrit≈1.5×1016V/cm). We present full simulation studies of exclusively photo-produced ϒ and high-mass dileptons in Pb-Pb collisions at the LHC.
