Search for new physics in charm processes

Abstract

Charm procceses are usually not considered to be favorable candidates in the search for new physics. Recent disagreement between experimental and lattice QCD results on the D_s decay constant has motivated us to systematically reinvestigate role of leptoquarks in rare charm meson decays. We include constrains coming from the light meson decays.
