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…
Running coupling constant and mass anomalous dimension of six-flavor SU(2) gauge theory
M. Hayakawa, K. -I. Ishikawa, S. Takeda +1
In the exploration of viable models of dynamical electroweak symmetry breaking, it is essential to locate the lower end of the conformal window and know the mass anomalous dimensio…
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…
Running coupling constant of ten-flavor QCD with the Schrödinger functional method
M. Hayakawa, K. -I. Ishikawa, Y. Osaki +3
Walking technicolor theory attempts to realize electroweak symmetry breaking as the spontaneous chiral symmetry breakdown caused by the gauge dynamics with slowly varying gauge cou…
Improving many flavor QCD simulations using multiple GPUs
M. Hayakawa, K. -I. Ishikawa, Y. Osaki +3
We accelerate many-flavor lattice QCD simulations using multiple GPUs. Multiple pseudo-fermion fields are introduced additively and independently for each flavor in the many-flavor…
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…

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…
Loops versus Matrices - The nonperturbative aspects of noncritical string
M. Hanada, M. Hayakawa, N. Ishibashi +4
The nonperturbative aspects of string theory are explored for non-critical string in two distinct formulations: loop equations and matrix models. The effects corresponding to D-bra…
Perturbative world-volume dynamics of the bosonic membrane and string
M. Hayakawa, N. Ishibashi
We study the world-volume theory of a bosonic membrane perturbatively and discuss if one can obtain any conditions on the number of space-time dimensions from the consistency of th…
Remarks on the Hadronic Effect in Muon : Low Energy Behavior of - Scattering
M. Hayakawa
The behavior of the - scattering amplitude (where , or ) in the low pion momentum limit is studied motivated by its relevance to the theory of muon $g…
