Photoproduction of p0 Mesons in Ultra-Peripheral D-AU Collisions at RHIC
… rho meson is copiously produced in high-energy collisions. Sometimes these oppositely directed beams of charged nuclei (ions) interact head-on resulting in a central collision. But often these nuclei narrowly miss each other and interact through electromagnetic fields. This phenomenon, known as …

Analysis of ρº (Neutral Rho) Decay from Ultra-Peripheral Collisions in Lead-Lead Interactions at ALICE
… analysis for rho meson production during ultra-peripheral collisions at A Large Ion Collider Experiment (ALICE) on the Large Hadron Collider at CERN. It also contains a discussion of the ALICE electromagnetic calorimeter (EMCal) and its uses in pion rejection. An overview of ALICE …

Angular Correlation of Emitted Neutrons Due to Giant Dipole Resonance in Ultra Peripheral Collisions
In an ultra peripheral collision with two gold ions, two virtual photons are exchanged, which excites the nuclei into a mutual giant dipole resonance (GDR) state. This excited state decays most often via neutron emission. The two emitted neutrons have an expected angular correlation based on the …

Incoherent Photoproduction of $\phi$ Mesons in Ultra-Peripheral Pb+Pb Collisions at $\sqrt{s_{NN}}$ = 5.02 TeV
… located at the LHC which observes the lead+lead collisions. During Run 2 at the LHC, a center of mass energy of 5.02 TeV per nucleon was achieved. An ultra peripheral collision occurs when the lead nuclei miss each other, having an impact parameter greater than twice the radius of the nucleus. …

Studying quantum correlations and multi-hadron states using high energy quasi-real photons
Physicists use particle accelerators to probe the fundamental structure of matter by colliding particles at energies sufficient to resolve sub-nuclear degrees of freedom. The resulting final states provide insight into the underlying dynamics of nature, enabling the discovery of new particles, the …
