Overview
We study B->Ka transition as a powerful probe of the heavy QCD axion (mass~GeV) by performing necessary 2-loop calculations for the first time. Such an axion is kinematically inaccessible or poorly constrained by most experimental probes. We will discuss some interesting subtleties of our calculation and present limits and projections on the axion parameter space using B-physics results.
