Lattice investigation of custodial two-Higgs-doublet model at weak quartic couplings

Guilherme Catumba, Atsuki Hiraguchi, Wei-Shu Hou +5

The gauged custodial two-Higgs-doublet model, which shares the same global-symmetry properties with the standard model, is studied non-perturbatively on the lattice. The…

Progress in lattice simulations for two Higgs doublet models

Guilherme Catumba, Atsuki Hiraguchi, George W. -S Hou +5

The custodial Two-Higgs-Doublet-Model with SU(2) gauge fields is studied on the lattice. This model has the same global symmetry structure as the Standard Model but the additional…

Lattice study of SU(2) gauge theory coupled to four adjoint Higgs fields

Guilherme Catumba, Atsuki Hiraguchi, Wei-Shu Hou +5

Gauge theories with matter fields in various representations play an important role in different branches of physics. Recently, it was proposed that several aspects of the interest…

Study of 3-dimensional SU(2) gauge theory with adjoint Higgs as a model for cuprate superconductors

Guilherme Catumba, Atsuki Hiraguchi, George W. -S. Hou +5

We study a 3-dimensional SU(2) gauge theory with 4 Higgs fields which transform under the adjoint representation of the gauge group, that has been recently proposed by Sachdev et a…

Lattice investigation of the general Two Higgs Doublet Model with gauge fields

Guilherme Catumba, Atsuki Hiraguchi, George W. -S Hou +5

We study the most general Two Higgs Doublet Model with gauge fields on the lattice. The phase space is probed through the computation of gauge-invariant global observables…

Study of SU(2) gauge theories with multiple Higgs fields in different representations

Guilherme Catumba, Atsuki Hiraguchi, George W. -S. Hou +5

We study two different SU(2) gauge-scalar theories in 3 and 4 spacetime dimensions. Firstly, we focus on the 3 dimensional SU(2) theory with multiple Higgs fields in the adjoint re…

Monopoles of the Dirac type and color confinement in QCD -- First results of SU(3) numerical simulations without gauge fixing

Katsuya Ishiguro, Atsuki Hiraguchi, Tsuneo Suzuki

If non-Abelian gauge fields in QCD have a line-singularity leading to non-commutativity with respect to successive partial-derivative operations, the non-Abelian Bianchi id…

Monopoles of the Dirac type and color confinement in QCD

Tsuneo Suzuki, Atsuki Hiraguchi, Katsuya Ishiguro

We present results of Monte-Carlo studies of a new color confinement scheme proposed recently due to Abelian-like monopoles of the Dirac type corresponding in the continuum…

New Abelian-like monopoles and the dual Meissner effect

Atsuki Hiraguchi, Katsuya Ishiguro, Tsuneo Suzuki

Violation of non-Abelian Bianchi identity can be regarded as Abelian-like monopole currents in the continuum SU(N) QCD. Three Abelian-like monopoles, when defined in SU(2)…
