Non-perturbative O(a) improvement of the SU(3) sextet model
Martin Hansen
We calculate non-perturbatively the coefficient c_sw required for O(a) improvement of the SU(3) gauge theory with Nf = 2 fermions in the two-index symmetric (sextet) representation…
SIMP model at NNLO in chiral perturbation theory
Martin Hansen, Kasper Langaeble, Francesco Sannino
We investigate the phenomenological viability of a recently proposed class of composite dark matter models where the relic density is determined by 3 to 2 number-changing processes…
A simple method to optimize HMC performance
Andrea Bussone, Michele Della Morte, Vincent Drach +4
We present a practical strategy to optimize a set of Hybrid Monte Carlo parameters in simulations of QCD and QCD-like theories. We specialize to the case of mass-preconditioning, w…
Consistency tests for Planck and WMAP in the low multipole domain
Anne Mette Frejsel, Martin Hansen, Hao Liu
Recently, full sky maps from Planck have been made publicly available. In this paper, we do consistency tests for the three Planck CMB sky maps. We assume that the difference betwe…
The SU(3) Sextet Model with Wilson Fermions
Martin Hansen, Vincent Drach, Claudio Pica
We investigate the spectrum and IR properties of the SU(3) "sextet" model with two Dirac fermions in the two-index symmetric representation via lattice simulations. This model is a…
Composite Higgs Dynamics on the Lattice
Claudio Pica, Vincent Drach, Martin Hansen +1
We investigate the spectrum of the SU(2) gauge theory with = 2 flavors of fermions in the fundamental representation, in the continuum, using lattice simulations. This model…
