In recent years, effective field theory (EFT) has achieved many successes in hadronic and low-energy nuclear physics, and the investigation of wobbling motion of triaxially deformed nuclei has become one of hottest topics in nuclear structure physics. In our previous work [1, 2], the EFT has been extended successfully to investigate the rotational and vibrational motions of triaxially deformed even-even nuclei. In this work, the EFT is further extended to investigate the collective motion of triaxial odd-mass nuclei. This extension requires a systematic treatment of the coupling between the single-particle motion and the collective rotational motion. The applicability of the obtained EFT is examined to study the wobbling motion in Lu isotopes.
