A dual description of quarks and baryons: Quarkyonic matter within a relativistic quark model
Tsuyoshi Miyatsu, Myung-Ki Cheoun, Koichi Saito
We investigate quarkyonic matter within a relativistic quark model by combining the dual quarkyonic picture with the quark-meson coupling (QMC) model. Using relativistic gaussian q…
Constraining the nuclear equation of state from terrestrial experiments and neutron star observations using relativistic mean-field models
Tsuyoshi Miyatsu, Myung-Ki Cheoun, Kyungsik Kim +1
We investigate the nuclear equation of state (EoS) for isospin-asymmetric matter using a new set of RMF interactions with the - and - mixing, referred to as the OME…
Quarkyonic Quark-Meson Coupling Model for Nuclear and Neutron Matter
Koichi Saito, Tsuyoshi Miyatsu, Myung-Ki Cheoun
We unite the dual quarkyonic model with the quark-meson coupling (QMC) model to construct a novel nuclear model based on the quark degrees of freedom, which can cover a wide range…
Equation of state for hyperonic neutron-star matter in SU(3) flavor symmetry
Tsuyoshi Miyatsu, Myung-Ki Cheoun, Kyungsik Kim +1
Using a relativistic mean-field model calibrated to finite-nucleus observables and bulk properties of dense nuclear matter, we investigate hyperonic neutron-star matter within an S…
Novel features of asymmetric nuclear matter from terrestrial experiments and astrophysical observations of neutron stars
Tsuyoshi Miyatsu, Myung-Ki Cheoun, Kyungsik Kim +1
The accurate measurement of neutron skin thickness of Pb by the PREX Collaboration suggests a large value of the nuclear symmetry energy slope parameter, , whereas the s…
Effect of isoscalar and isovector scalar fields on baryon semileptonic decays in nuclear matter
Koichi Saito, Tsuyoshi Miyatsu, Myung-Ki Cheoun
The precise determination of the Cabibbo-Kobayashi-Maskawa (CKM) matrix elements is very important, because it could be a clue to new physics beyond Standard Theory. This is partic…
