Contribution
It provides the first detailed calculation of Wilson coefficients for these decays within the Standard Model and identifies decay regions sensitive to beyond Standard Model physics.
Findings
Identified decay distribution window for new physics detection
Calculated Standard Model Wilson coefficients for charm decays
Studied effects of leptoquark models on decay processes
Abstract
An analysis of charm mesons decaying semileptonically via Flavor Changing Neutral Currents is presented. We calculate the Wilson coefficients within the Standard Model. A window in the decay distribution, where physics beyond the Standard Model could be measured is identified. Exemplary, we study effects of leptoquark models.
