1. Nucleon and Δ isobar in a strong magnetic field / Yakhshiev, Ulugbek ; Kim, Hyun-Chul ; Oka, Makoto
We investigate the static properties of the nucleon in the presence of strong magnetic fields and discuss the consequent changes of the nucleon structure, based on the Skyrme model. [...]

2. Further signatures to support the tetraquark mixing framework for the two light-meson nonets / Kim, Hungchong ; Kim, K. S. ; Cheoun, Myung-Ki ; Jido, Daisuke ; et al
In this work, we investigate additional signatures to support the tetraquark mixing framework that has been recently proposed as a possible structure for the two nonets, namely a0(980), K0*(800), f0(500), and f0(980) in the light nonet and a0(1450), K0*(1430), f0(1370), and f0(1500) in the heavy nonet.

3. Hadronic Paschen–Back effect / Iwasaki, Sachio ; Oka, Makoto ; Suzuki, Kei ; Yoshida, Tetsuya
We find a novel phenomenon induced by the interplay between a strong magnetic field and finite orbital angular momenta in hadronic systems, which is analogous to the Paschen–Back effect observed in the field of atomic physics. [...]

5. Tetraquark mixing framework for isoscalar resonances in light mesons / Kim, Hungchong ; Kim, K. S. ; Cheoun, Myung-Ki ; Oka, Makoto
Recently, a tetraquark mixing framework has been proposed for light mesons and applied more or less successfully to the isovector resonances, a0(980), a0(1450), as well as to the isodoublet resonances, K0*(800),K0*(1430). [...]

9. QCD sum rules on the complex Borel plane / Araki, Ken-Ji ; Ohtani, Keisuke ; Gubler, Philipp ; Oka, Makoto
Borel-transformed QCD sum rules conventionally use a real-valued parameter (the Borel mass) for specifying the exponential weight over which hadronic spectral functions are averaged. [...]
