Quark confinement: dual superconductor picture based on a non-Abelian Stokes theorem and reformulations of Yang-Mills theory

- K. Kondo, S. Kato, A. Shibata, T. Shinohara
- Physics
- 4 September 2014

The purpose of this paper is to review the recent progress in understanding quark confinement. The emphasis of this review is placed on how to obtain a manifestly gauge-independent picture for quark… Expand

Light flavor-singlet scalars and walking signals in Nf=8 QCD on the lattice

- Y. Aoki, T. Aoyama, +9 authors T. Yamazaki
- Physics
- 22 October 2016

Based on the highly improved staggered quark action, we perform lattice simulations of Nf=8 QCD and confirm our previous observations, both of a flavor-singlet scalar meson (denoted as σ) as light as… Expand

Flavor-singlet spectrum in multi-flavor QCD

- Y. Aoki, T. Aoyama, +9 authors T. Yamazaki
- Physics
- 18 October 2017

Studying SU(3) gauge theories with increasing number of light fermions is relevant both for understanding the strong dynamics of QCD and for constructing strongly interacting extensions of the… Expand

Lattice study of conformality in twelve-flavor QCD

- Y. Aoki, T. Aoyama, +6 authors T. Yamazaki
- Physics
- 12 July 2012

We study infrared conformality of the twelve-flavor QCD on the lattice. Utilizing the highly improved staggered quarks (HISQ) type action which is useful to study the continuum physics, we analyze… Expand

Light composite scalar in eight-flavor QCD on the lattice

- Y. Aoki, T. Aoyama, +8 authors T. Yamazaki
- Physics
- 3 September 2013

We present the first observation of a flavor-singlet scalar meson as light as the pion in $N_f=8$ QCD on the lattice, using the Highly Improved Staggered Quark action. Such a light scalar meson can… Expand

Walking signals in Nf=8 QCD on the lattice

- Y. Aoki, T. Aoyama, +6 authors T. Yamazaki
- Physics
- 27 February 2013

We investigate walking signals of Nf = 8 QCD through meson spectrum using the HISQ (highly improved staggered quark) action. Our data (the pion decay constant, the p and r meson masses and the chiral… Expand
