Investigation of the phase structure of a chirally-invariant Higgs-Yukawa model / Bulava, John (CERN) ; Gerhold, Philipp (Humboldt U., Berlin ; NIC, Zeuthen) ; Hou, George W.-S. ; Jansen, Karl (NIC, Zeuthen) ; Knippschild, Bastian (Taiwan, Natl.

We present new data on our ongoing project on the investigation of the phase structure of the Higgs-Yukawa model at large bare Yukawa couplings. The data presented last year are extended in terms of statistics, the number of bare Yukawa couplings at existing, and new larger volumes. [...]

Higgs-Yukawa model in chirally-invariant lattice field theory / Bulava, John (CERN) ; Gerhold, Philipp (Humboldt U., Berlin ; NIC, Zeuthen) ; Jansen, Karl (NIC, Zeuthen) ; Kallarackal, Jim (Humboldt U., Berlin ; NIC, Zeuthen) ; Knippschild, Bastian (Taiwan, Natl.

Non-perturbative numerical lattice studies of the Higgs-Yukawa sector of the standard model with exact chiral symmetry are reviewed. In particular, we discuss bounds on the Higgs boson mass at the standard model top quark mass, and in the presence of heavy fermions. [...]

Chiao Tung U.) ; Smigielski, Brian (Taiwan, Natl. Taiwan U.)
In this article, we present an ongoing lattice study of the Higgs-Yukawa model, in the regime of strong-Yukawa coupling, using overlap fermions. We investigated the phase structure in this regime by computing the Higgs vacuum expectation value, and by exploring the finite-size scaling behaviour of the susceptibility corresponding to the magnetisation.

Reducing Residual-Mass Effects for Domain-Wall Fermions / Jansen, Karl (NIC, Zeuthen ; DESY, Zeuthen) ; Nagai, Kei-ichi (CERN)
It has been suggested to project out a number of low-lying eigenvalues of the four-dimensional Wilson--Dirac operator that generates the transfer matrix of domain-wall fermions in order to improve simulations with domain-wall fermions. We investigate how this projection method reduces the residual chiral symmetry-breaking effects for a finite extent of the extra dimension. [...]

Residual mass effects in improved domain wall fermions / Hernandez, Pilar (CERN) ; Jansen, Karl (NIC, Zeuthen ; DESY, Zeuthen) ; Nagai, Kei-ichi (CERN)
In order to improve simulations with domain wall fermions (DWFs), it has been suggested to project out a number of low-lying eigenvalues of the 4-dimensional Dirac operator that generates the transfer matrix of DWF. We investigate how this projection method affects chiral properties of quenched DWF. [...]
