Probing New Physics in Charm Couplings with Kaon and Other Hadron Processes

Abstract

It is possible that the low-energy effects of physics beyond the standard model can be parametrized mainly by anomalous couplings of quarks to the W boson. Such couplings can generate potentially significant contributions to various transitions that can be probed by current and future experiments. This work explores constraints on anomalous charm-W couplings from a number of CP-conserving and -violating processes involving the kaon and other flavored hadrons.
