Evolution of the coupling constant in SU(2) lattice gauge theory with two adjoint fermions
- A. Hietanen, K. Rummukainen, Kimmo Tuominen Florida International University, U. Helsinki, U. O. Oulu, University of Jyvaskyla
- Physics
- 6 April 2009
We measure the evolution of the coupling constant using the Schroedinger functional method in the lattice formulation of SU(2) gauge theory with two massless Dirac fermions in the adjoint… Expand
Fundamental composite Higgs dynamics on the lattice: SU(2) with two flavors
- A. Hietanen, R. Lewis, C. Pica, Francesco Sannino
- Physics
- 10 April 2014
A bstractIn reference [1] a unified description, both at the effective and fundamental Lagrangian level, of models of composite Higgs dynamics was proposed. In the unified framework the Higgs itself… Expand
Composite Goldstone dark matter: experimental predictions from the lattice
- A. Hietanen, R. Lewis, C. Pica, Francesco Sannino
- Physics
- 19 August 2013
A bstractWe study, via lattice simulations, the nonperturbative dynamics of SU(2) gauge theory with two fundamental Dirac flavors. The model can be used simultaneously as a template for composite… Expand
Spectrum of SU(2) lattice gauge theory with two adjoint Dirac flavours
- A. Hietanen, J. Rantaharju, K. Rummukainen, K. Tuominen
- Physics
- 8 December 2008
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 study… Expand
Three-dimensional physics and the pressure of hot QCD
- A. Hietanen, K. Kajantie, M. Laine, K. Rummukainen, Y. Schroder
- Physics
- 28 November 2008
We update Monte Carlo simulations of the three-dimensional $\mathrm{SU}(3)+\mathrm{\text{adjoint}}$ Higgs theory, by extrapolating carefully to the infinite volume and continuum limits, in order to… Expand
SU(2) Gauge Theory with Two Fundamental Flavours: a Minimal Template for Model Building
- R. Arthur, V. Drach, Martin Hansen, A. Hietanen, C. Pica, Francesco Sannino
- Physics
- 21 February 2016
We investigate the continuum spectrum of the SU(2) gauge theory with Nf = 2 flavours of fermions in the fundamental representation. This model provides a minimal template which is ideal for a wide… Expand
The vector meson mass in the large N limit of QCD
- A. Hietanen, R. Narayanan, R. Patel, C. Prays
- Physics
- 23 January 2009
The vector meson mass is computed as a function of quark mass in the large N limit of QCD. We use continuum reduction and directly compute the vector meson propagator in momentum space. Quark… Expand
The large N limit of four dimensional Yang-Mills field coupled to adjoint fermions on a single site lattice
- A. Hietanen, R. Narayanan
- Physics
- 12 November 2009
We consider the large N limit of four dimensional SU(N) Yang-Mills field coupled to adjoint fermions on a single site lattice. We use perturbative techniques to show that the ZN4 center-symmetries… Expand

Non-perturbative plaquette in 3-D pure SU(3)
- A. Hietanen, K. Kajantie, M. Laine, K. Rummukainen, Y. Schroder
- Physics
- 23 September 2005
We present a determination of the elementary plaquette and, after the subsequent ultraviolet subtractions,
of the finite part of the gluon condensate, in lattice regularization in three-dimensional… Expand
