Further signatures to support the tetraquark mixing framework for the two light-meson nonets
Hungchong Kim, K. S. Kim, Myung-Ki Cheoun +2
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 $a_…
Radiative transitions of doubly charmed baryons in lattice QCD
H. Bahtiyar, K. U. Can, G. Erkol +2
We evaluate the spin- spin- electromagnetic transitions of the doubly charmed baryons on 2+1 flavor, PACS-CS lattices with a pion mass of Me…
Quark model estimate of hidden-charm pentaquark resonances
Emiko Hiyama, Atsushi Hosaka, Makoto Oka +1
A quark model, which reproduces the ground-state mesons and baryons, i.e., the threshold energies, is applied to the configurations, where is a light quark and~…
Resonance in the potential model
Saori Maeda, Makoto Oka, Yan-Rui Liu
We calculate two-body , and resonance states of (, , or ) and using the complex scaling method. We employ the $…
Hadronic Paschen-Back effect
Sachio Iwasaki, Makoto Oka, Kei Suzuki +1
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 e…
Non-perturbative evaluation for anomalous dimension in 2-dimensional O(3) sigma model
Sergio Calle Jimenez, Makoto Oka, Kiyoshi Sasaki
We calculate the wave-function renormalization in 2-dimensional O(3) sigma model, non- perturbatively. It is evaluated in a box with a finite spatial extent. We determine the anoma…
