Heavy QCD axions in B decays

Sabyasachi Chakraborty

Florida State University

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. W
e will discuss some interesting subtleties of our calculation and present limits and projections on the axion parameter space using B-physics results.
