Determining the conformal window: SU(2) gauge theory with Nf = 4, 6 and 10 fermion flavours
A bstractWe study the evolution of the coupling in SU(2) gauge field theory with Nf = 4, 6 and 10 fundamental fermion flavours on the lattice. These values are chosen close to the expected edges ofExpand

Sp(4) gauge theories on the lattice: quenched fundamental and antisymmetric fermions
We perform lattice studies of meson mass spectra and decay constants of the $Sp(4)$ gauge theory in the quenched approximation. We consider two species of (Dirac) fermions as matter field content,Expand

Non-perturbatively improved clover action for SU(2) gauge + fundamental and adjoint representation fermions
The research of strongly coupled beyond-the-standard-model theories has generated significant interest in non-abelian gauge field theories with different number of fermions in differentExpand

Spectrum of SU(2) lattice gauge theory with two adjoint Dirac flavours
An SU(2) gauge theory with two fermions transforming under the adjoint representation of the gauge group may appear conformal or almost conformal in the infrared. We use lattice simulations to studyExpand

Ideal walking dynamics via a gauged NJL model
According to the Ideal Walking Technicolor paradigm large mass anomalous dimensions arise in gauged Nambu--Jona-Lasinio (NJL) models when the four-fermion coupling is sufficiently strong to induceExpand

A simple method to optimize HMC performance
TLDR
We present a practical strategy to optimize a set of Hybrid Monte Carlo parameters in simulations of QCD and QCD-like theories, based on the existence of a shadow Hamiltonian. Expand

Benchmark results in the 2D lattice Thirring model with a chemical potential
We study the two dimensional lattice Thirring model in the presence of a fermion chemical po- tential. Our model is asymptotically free, contains massive fermions that mimic a baryon and light bosonsExpand

Conformal window in SU(2) with fundamental fermions
We present the updated results of the infrared behavior of the SU(2) 6 and 8 fundamental representation fermions. We use the gradient flow method with the Schr\"odinger functional boundary conditionsExpand

N ov 2 01 5 Wilson Fermions with Four Fermion Interactions
We present a lattice study of a four fermion theory, known as N mbu Jona-Lasinio (NJL) theory, via Wilson fermions. Four fermion interactions natura lly occur in several extensions of the StandardExpand
