$D D ˉ^{*}$ - $π J / ψ$ scatterings of coupled channels for $Z_{c} (3900)$ channel

Yukihiro Abe, Yasuhiro Yamaguchi, Atsushi Hosaka

We perform coupled channel analysis for $D D ˉ^{*}$ , $J / ψ π$ and related meson pairs for the $Z_{c} (3900)$ channel in an effective model of hadrons and quarks. The model incorporates…

Quarkonium spectra with magnetically induced anisotropic confinement

Ahmad Jafar Arifi, Kei Suzuki

Strong magnetic fields modify the force that confines quarks inside hadrons and make it direction-dependent. Using quark-antiquark potentials obtained from lattice simulations as i…

Inverse Excitation Hierarchy in Doubly-Heavy Tetraquarks within the Diquark Model

Maximilian Weber, Daiki Suenaga, Masayasu Harada

We investigate the $T_{cc}$ tetraquark, treating it as a bound state of a heavy diquark and a light antidiquark. Using the Silvestre-Brac potential and solving the Schrödinger equa…

Physics of strong electromagnetic fields in relativistic heavy-ion collisions

Koichi Hattori

I discuss several roles of the strong electromagnetic fields created by relativistic heavy-ion collisions. These phenomena call for theoretical and experimental developments to und…

Landau-Zener-Stückelberg-Majorana dynamics of magnetized quarkonia

Ahmad Jafar Arifi, Kei Suzuki

The mass spectrum of hadrons in magnetic fields features avoided level-crossing structures arising from the mixing of spin eigenstates. In this work, we investigate the impact of l…

Roles of $U (1)$ axial anomaly effects in cold and dense two-color QCD with $2 + 2$ flavors

Manato Sakai, Daiki Suenaga

We explore phase structures and hadron mass spectra in cold and dense two-color QCD with $2 + 2$ flavors where the sign problem disappears. We particularly focus on $U (1)$ axial anom…
