STARlight: A C++ Object-Oriented Monte Carlo Event Generator for Ultra-Peripheral Collisions
Ultra-peripheral collisions occur when nuclei pass one another without overlapping. The intense electric fields present can be treated as a flux of virtual photons; these photons can interact with the other nucleus or each other, producing a range of particles, including vector mesons and lepton …

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 …

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 …

Studies of the Photoproduction of Charm-Anticharm Resonances in Ultra-Peripheral Collisions of Lead Ions in ALICE at the LHC
… particle final state, π^+π^- K^+K^- in Pb-Pb ultra-peripheral collisions (UPCs). The second case studies the two-photon production of an all charmed tetraquark state decaying into a four lepton final state.|The simulations for the first case predict a total of about one hundred candidates in a …

Heavy Quark Jet Rest Frame Identification Technique and Incoherent Phi Analysis AT ALICE
… the photo-nuclear production of the Phi meson in Ultra Peripheral Collisions (UPCs) at ALICE. A unique jet identification technique was developed which substantially reduces the number of non-heavy flavor jets in a jet sample. Coherently produced Phi mesons are not observed at ALICE while …

Photoproduction of ηc mesons in ultra-peripheral Pb+Pb collisions at √sNN= 5.02 TeV at the LHC
High energy ultra-peripheral collisions provide unique circumstances to examine the exclusive photoproduction of heavy mesons. The Pb+Pb collisions generated at CERN's Large Hadron Collider at √sNN = 5:02 TeV provide new data which has been predicted to have a reconstructable signal for the ηc …

Measurement of the Anomalous Magnetic Moment of Tau Lepton with CMS Experiments and Improvements to the Zero Degree Calorimeters at CMS
Ultra Peripheral Collisions at the Large Hadron Collider (LHC) provide the best environment for testing high-energy quantum electrodynamic (QED) scattering processes since the shutdown of the Large Electron-Positron Collider. Measurements of the anomalous magnetic moment of leptons have recently …

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. …
