QCD sum rule approach to Okamoto-Nolen-Schiffer anomaly
Hiroyuki Sagawa, Tomoya Naito, Xavier Roca-Maza +1
A new framework is introduced to connect between a charge symmetry breaking (CSB) energy density functional (EDF) and the low-energy constants derived from quantum chromodynamics (…
Possible inconsistency between phenomenological and theoretical determinations of charge symmetry breaking in nuclear energy density functionals
Tomoya Naito, Gianluca Colò, Tetsuo Hatsuda +3
We summarize the recent progress on the determination of the charge symmetry breaking term of nuclear energy density functionals. We point out that the strength of the term determi…
Functional renormalization group approach to conventional theory of superfluidity and beyond
Yuya Tanizaki, Gergely Fejős, Tetsuo Hatsuda
Fermionic functional renormalization group (FRG) is applied to describe the superfluid phase transition of the two-component fermionic system with attractive contact interaction. C…
Nuclear Forces from Lattice QCD
T. Hatsuda
A method to extract nucleon-nucleon (NN) potentials from the Bethe-Salpeter amplitude in lattice QCD is presented. It is applied to the two nucleons on the lattice with quenched QC…
In-medium Σ^0-ΛMixing in QCD Sum Rules
N. Yagisawa, T. Hatsuda, A. Hayashigaki
The Σ^0-Λmixing angle in isospin-asymmetric nuclear medium is investigated by using QCD sum rules. From the general consideration of the in-medium baryonic correlations, in-medium…
In-medium pi-pi Correlation Induced by Partial Restoration of Chiral Symmetry
D. Jido, T. Hatsuda, T. Kunihiro
We show that both the linear and the non-linear chiral models give an enhancement of the pi-pi cross section near the 2pi threshold in the scalar-iso-scalar (I=J=0) channel in nucl…
