Monopole and instanton effects on connected and disconnected correlations for scalar density
Masayasu Hasegawa
This study investigates the effects on the connected and disconnected correlations for the scalar density that are induced by created monopoles and instantons in the QCD vacuum. To…
Monopoles, spectra of overlap fermions, and eta-prime meson in external magnetic fields
Masayasu Hasegawa
The effects of external magnetic fields on monopoles, spectra of the overlap Dirac operator, instantons, and the mass of the eta-prime meson are examined by conducting lattice QCD…
Color confinement, chiral symmetry breaking, and catalytic effect induced by monopole and instanton creations
Masayasu Hasegawa
Our research reveals the relations among monopoles, color confinement, instantons, and chiral symmetry breaking which experiments can detect, by numerical calculations of lattice g…
Instanton effects on chiral symmetry breaking and hadron spectroscopy
Masayasu Hasegawa
This project aims to give indications to find monopole and instanton effects in QCD on the observables by experiments. First, we add the monopole and anti-monopole to the QCD vacuu…
Monopole and instanton effects in QCD
Masayasu Hasegawa
We aim to show the effects of the magnetic monopoles and instantons in quantum chromodynamics (QCD) on observables; therefore, we introduce a monopole and anti-monopole pair in the…
Chiral symmetry breaking, instantons, and monopoles
Adriano Di Giacomo, Masayasu Hasegawa
The purpose of this study is to show that monopoles induce the chiral symmetry breaking. In order to indicate the evidence, we add one pair of monopoles with magnetic charges to th…
Chiral symmetry breaking and monopoles
Adriano Di Giacomo, Masayasu Hasegawa, Fabrizio Pucci
To understand the relation between the chiral symmetry breaking and monopoles, the chiral condensate which is the order parameter of the chiral symmetry breaking is calculated in t…
Instantons and Monopoles
Adriano Di Giacomo, Masayasu Hasegawa
This study is part of a research program aimed to investigate the relations between instantons, monopoles, and chiral symmetry breaking. Monopoles are important 3-dimensional topol…
Zero modes, Instantons, and Monopoles
Adriano Di Giacomo, Masayasu Hasegawa
The purpose of this study is to show the relations between monopoles instantons and Chiral symmetry breaking. First, in order to show the relation between instantons and monopoles,…
Zero modes of Overlap fermions, instantons, and monopoles
Adriano Di Giacomo, Masayasu Hasegawa
The purpose of this study is to investigate the relations between instantons, monopoles, and Chiral symmetry breaking. The monopoles are important topological configurations existi…
High-loop perturbative renormalization constants for Lattice QCD (III): three-loop quark currents for Iwasaki gauge action and n_f=4 Wilson fermions
M. Brambilla, F. Di Renzo, M. Hasegawa
This is the third of a series of papers on three-loop computation of renormalization constants for Lattice QCD. Our main point of interest are results for the regularization define…
Gauge invariance of color confinement due to the dual Meissner effect caused by Abelian monopoles
T. Suzuki, M. Hasegawa, K. Ishiguro +2
The mechanism of non-Abelian color confinement is studied in SU(2) lattice gauge theory in terms of the Abelian fields and monopoles extracted from non-Abelian link variables witho…
