The nature of Dark Matter (DM) remains one of the greatest puzzles in particle physics and cosmology. While overwhelming observational evidence across galactic and cosmological scales confirms its existence, decades of experiments have only verified its gravitational interaction. Key properties of DM -- such as its spin, mass, non-gravitational interactions, stabilizing symmetry, number of...
In the RHIC spin program, the Atomic Polarized Hydrogen Gas Jet Target (HJET) was constructed to measure the absolute polarization of proton beams. Recoil protons from the vertically polarized proton beam CNI (Coulomb Nuclear Interference) scattering off the vertically polarized proton jet target were detected using left-right symmetric Si detectors. Since the jet polarization is well known,...
Many theories beyond the Standard Model (SM) have been proposed to address several of the SM shortcomings, such as explaining why the Higgs boson is so light, the origin of neutrino masses, or the observed pattern of masses and mixing angles in the quark and lepton sectors. Many of these beyond-the-SM extensions predict new particles or interactions directly accessible at the LHC. This talk...
