On the extraction of spectral densities from lattice correlators
Martin Hansen, Alessandro Lupo, Nazario Tantalo
Hadronic spectral densities are important quantities whose non-perturbative knowledge allows for calculating phenomenologically relevant observables, such as inclusive hadronic cro…
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…
Extending Chiral Perturbation Theory with an Isosinglet Scalar
Martin Hansen, Kasper Langaeble, Francesco Sannino
We augment the chiral Lagrangian by an isosinglet scalar and compute the one-loop radiative corrections to the pion mass and decay constant, as well as the scalar mass. The calcula…
Composite (Goldstone) Higgs Dynamics on the Lattice: Spectrum of SU(2) Gauge Theory with two Fundamental Fermions
Rudy Arthur, Vincent Drach, Martin Hansen +4
We study the meson spectrum of the SU(2) gauge theory with two Wilson fermions in the fundamental representation. The theory unifies both Technicolor and composite Goldstone Boson…
Scattering lengths in SU(2) gauge theory with two fundamental fermions
R. Arthur, V. Drach, M. Hansen +3
We investigate non perturbatively scattering properties of Goldstone Bosons in an SU(2) gauge theory with two Wilson fermions in the fundamental representation. Such a theory can b…
