Degeneracy of doubly heavy baryons from heavy quark symmetry
Yong-Liang Ma, Masayasu Harada
The spectroscopy of the doubly heavy baryons including different heavy quarks is studied based on the heavy quark symmetry of QCD. We point out that, when the two heavy quarks are…
Appearance of novel modes of mesons in the Dual Chiral Density Wave
Daiki Suenaga, Masayasu Harada
We calculate dispersion relations for , , and mesons in the Dual Chiral Density Wave (DCDW) where the chiral symme…
Effects of scalar mesons in a Skyrme model with hidden local symmetry
Bing-Ran He, Yong-Liang Ma, Masayasu Harada
We study the effects of light scalar mesons on the skyrmion properties by constructing and examining a mesonic model including pion, rho meson, and omega meson fields as well as tw…
Extended Goldberger-Treiman relation obtained in a three-flavor parity doublet model
Hiroki Nishihara, Masayasu Harada
We study masses and decay widths of positive and negative parity nucleons using a three-flavor parity doublet model, in which we introduce three representations, $\left[({\bf 3} ,…
Doubly heavy baryons with chiral partner structure
Yong-Liang Ma, Masayasu Harada
The spectrum and dominant strong decay properties of the doubly heavy baryons are revisited by using a chiral effective model with chiral partner structure. By regarding the doubly…
Inhomogeneous quark condensate in compressed skyrmion matter
Masayasu Harada, Hyun Kyu Lee, Yong-Liang Ma +1
The inhomogeneous quark condensate, responsible for dynamical chiral symmetry breaking in cold nuclear matter, is studied by putting skyrmions onto the face-centered cubic crystal…
