Soft Collinear Effective Theory for Heavy QCD Axions

We develop a soft-collinear effective theory (SCET) framework for heavy QCD axion, considering two low-energy realizations and taking $B\to Ka$ as a benchmark mode. In the first realization, $aG\widetilde G$ is assumed to be the only independent axion interaction at the scale $\mu\sim m_b$. We show that eliminating the...
