Ultra-peripheral Collisions
Jesus Guillermo Contreras, Spencer Robert Klein
Photons in ultra-peripheral collisions of heavy ions (and protons) can be used for a variety of physics purposes - for studies of nuclear structure at low Bjorken, as probes of…
Azimuthal angular entanglement between decaying particles in ultra-peripheral ion collisions
Spencer R. Klein
Ultra-peripheral collisions (UPCs) involving relativistic heavy ions are a unique laboratory to study quantum correlations. The intense electromagnetic fields generate high rates o…
Probing Quantum Phenomena through Photoproduction in Relativistic Heavy-Ion Collisions
James Daniel Brandenburg, Spencer R. Klein, Zhangbu Xu +3
Photoproduction in ultra-peripheral relativistic heavy-ion collisions displays many unique features, often involving quantum mechanical coherence and two-source interference betwee…
Quantum mechanical aspects of coherent photoproduction: the limits of coherence, and multiple vector mesons
Spencer R. Klein
Quantum mechanics is central to coherent photoproduction in ultra-peripheral collisions (UPCs). This writeup will discuss some surprising aspects of UPCs that stem from these quant…
Heavy Flavour Production in Deep--Inelastic Scattering - Two--Loop Massive Operator Matrix Elements and Beyond
I. Bierenbaum, J. Blümlein, S. Klein
We calculate the O($\eps$)--term of the two--loop massive operator matrix elements for twist 2--operators, which contribute to the heavy flavour Wilson coefficients in unpolarized…
Interference in Exclusive Vector Meson Production in Heavy Ion Collisions
Spencer R. Klein, Joakim Nystrand
Photons emitted from the electromagnetic fields of relativistic heavy ions can fluctuate into quark anti-quark pairs and scatter from a target nucleus, emerging as vector mesons. T…
