  5. Analysis of Neutral D Meson Two-Body Decays to a Neutral Kaon and a Neutral Pion

    Kimmel, Taylor Douglas Jr.Virginia Tech2021

    Decays of neutral D mesons to final states containing K + π's could provide evidence for CP-violation from a source not accounted for in the Standard Model. Due to the interference between Cabibbo-favored and Cabibbo-suppressed transitions, a decay rate asymmetry of D0 → K0S π0 compared to D0 → …

    Hoffman, Alan MichaelMassachusetts Institute of Technology2009

    Twenty years of polarized lepton-nucleon scattering experiments have found that the contribution from quark spins (1/2[delta] [sigma]) to the spin of the proton is only ~ 35%. This has lead researchers to look elsewhere, specifically to gluon spin ([delta sigma]) for a large contribution to proton …
