Measurement of transverse spin asymmetries in polarized proton-proton collisions, and the realization of new electromagnetic calorimeters for forward physics
… data is acquired with a pair of electromagnetic calorimeters which were built as part of the thesis. All aspects of the calorimeters from design to data analysis are dis-cussed. The calorimeters are used to measure non-zero asymmetries at forward-rapidity. The measurements extend to higher pT …

Centrality Effects on Heavy-Flavor Quark Production and Invariant Yield in PHENIX Proton–Gold Collisions at Center-of-Mass Energy 200 GeV, and Assembly, Testing, Calibration, and Installation of the sPHENIX Hadronic Calorimeters
<p>Hadrons created in heavy-ion collisions interact with the open color-charge of the quark-gluon plasma through their constituent quarks. The medium imparts substantial modifications to heavy-flavor hadrons' momentum spectra. For collisions of small systems, the centrality of those collisions …

Jet radius and rapidity dependence of azimuthal correlations in photoproduced dijets
… pattern of neutron production in the Zero Degree Calorimeters as either having no neutrons on both sides (0n0n) or at least one neutron opposite the direction of the photon (0nXn). For jets of radius 0.4, ⟨cos(2φ)⟩ was found to be positive and independent of the neutron topology, suggesting a …
