Lattice Study on quantum-mechanical dynamics of two-color QCD with six light flavors
M. Hayakawa, K. -I. Ishikawa, S. Takeda +2
We investigate the chiral properties of SU(2) gauge theory with six flavors, i.e. six light Dirac fermions in the fundamental representations by lattice simulation, and point out t…
Lattice study on two-color QCD with six flavors of dynamical quarks
M. Hayakawa, K. -I. Ishikawa, Y. Osaki +2
We study the dynamics of SU(2) gauge theory with NF=6 Dirac fermions by means of lattice simulation to investigate if they are appropriate to realization of electroweak symmetry br…
Study of the running coupling constant in 10-flavor QCD with the Schrödinger functional method
N. Yamada, M. Hayakawa, K. -I. Ishikawa +3
The electroweak gauge symmetry is allowed to be spontaneously broken by the strongly interacting vector-like gauge dynamics. When the gauge coupling of a theory runs slowly in a wi…

The electroweak gauge symmetry is allowed to be spontaneously broken by the strongly interacting vector-like gauge dynamics. When the gauge coupling of a theory runs slowly in a wi…
Lattice gauge action suppressing near-zero modes of H_W
JLQCD collaboration, H. Fukaya, S. Hashimoto +5
We propose a lattice action including unphysical Wilson fermions with a negative mass m_0 of the order of the inverse lattice spacing. With this action, the exact zero mode of the…
