Diffraction in nuclear physics
Proton-Lead (p+Pb) collisions at the Large Hadron Collider provide a unique opportunity to study the dynamics of soft and hard scattering processes in nuclear targets, at the TeV scale.
The ATLAS experiment has measured the inclusive charged particle pseudorapidity distribution, the production of Z bosons and and the inclusive jet production in p+Pb collisions at $\sqrt{s_{NN}}$ = 5.02 TeV....

Ultra-peripheral collisions (UPCs) of heavy ions involve long range electromagnetic interactions at impact parameters larger than twice the nuclear radius. At TeV energies, the strong electromagnetic field due to the coherent action of the Z=82 proton charges generates a large flux of photons, which can be used for high-energy photoproduction studies. Heavy vector mesons (for example J/psi,...

Vector mesons are copiously produced in ultra-peripheral collisions(UPC).
In these collisions, the impact parameter is larger than the sum of the nuclear radii, implying that electromagnetic processes become dominant.
The cross section for heavy vector meson production is expected to be sensitive to the gluon distribution and can therefore probe nuclear gluon shadowing (Pb-Pb) and the...
