Tuning the hybrid Monte Carlo algorithm using molecular dynamics forces’ variances
© 2018 Elsevier B.V. Within the HMC algorithm, we discuss how, by using the shadow Hamiltonian and the Poisson brackets, one can achieve a simple factorization in the dependence of the Hamiltonian violations upon either ...
SU(3) sextet model with Wilson fermions
Composite Higgs Dynamics on the Lattice
We investigate the spectrum of the SU(2) gauge theory with $N_f$ = 2 flavors of fermions in the fundamental representation, in the continuum, using lattice simulations. This model provides a minimal template which has been ...
Nambu-Jona-Lasinio model with Wilson fermions
We present a lattice study of a Nambu Jona-Lasinio (NJL) model using Wilson fermions. Four fermion interactions are a natural part of several extensions of the Standard Model, appearing as a low energy description of a ...
Rho meson decay width in SU(2) gauge theories with 2 fundamental flavours
SU(2) gauge theories with two quark flavours in the fundamental representation are among the most promising theories of composite dynamics describing the electroweak sector. Three out of five Goldstone bosons in these ...
Adjoint SU(2) with Four Fermion Interactions
Four fermion interactions appear in many models of Beyond Standard Model physics. In Technicolour and composite Higgs models Standard Model fermion masses can be generated by four fermion terms. They are also expected to ...
