Meson screening masses from lattice QCD with two light and the strange quark

- M. Cheng, S. Datta,
+13 authors W. Söldner - Physics
- 2010

We present results for screening masses of mesons built from light and strange quarks in the temperature range of approximately between 140 MeV to 800 MeV. The lattice computations were performed… Expand

Sp(4)
gauge theories on the lattice: Quenched fundamental and antisymmetric fermions

- E. Bennett, D. K. Hong,
+6 authors Davide Vadacchino - PhysicsPhysical Review D
- 13 December 2019

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

- Anne Mykkanen, J. Rantaharju,
+4 authors Helsinki Institute of Physics University of Jyvaskyla - Physics
- 8 November 2010

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 different… 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

Determining the conformal window: SU(2) gauge theory with Nf = 4, 6 and 10 fermion flavours

- Tuomas Karavirta, J. Rantaharju, K. Rummukainen, K. Tuominen
- Physics
- 17 November 2011

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 of… Expand

Spectrum of SU(2) gauge theory with two fermions in the adjoint representation

- A. Hietanen, J. Rantaharju, K. Rummukainen, K. Tuominen
- Physics
- 21 October 2008

We present preliminary results of lattice simulations of SU(2) gauge theory with two Wilson fermions in the adjoint representation. This theory has recently attracted considerable attention because… Expand

+12 authors W. Soeldner - Physics
- 6 October 2010

We present results for screening masses of mesons built from light and strange quarks in the temperature range of approximately between 140 MeV to 800 MeV. The lattice computations were performed… Expand

Benchmark results in the 2D lattice Thirring model with a chemical potential

- V. Ayyar, S. Chandrasekharan, J. Rantaharju
- Physics
- 21 November 2017

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 bosons… Expand

Template Composite Dark Matter : SU(2) gauge theory with 2 fundamental flavours

Contribution to proceedings of the 33rd International Symposium on Lattice Field Theory (Lattice 2015), 14-18 July 2015, Kobe, Japan

The gradient flow running coupling in SU(2) gauge theory with $N_f=8$ fundamental flavors

- V. Leino, J. Rantaharju, T. Rantalaiho, K. Rummukainen, Joni M. Suorsa, K. Tuominen
- Physics
- 17 January 2017

We study the evolution of the coupling in SU(2) gauge field theory with $N_f=8$ fundamental fermion flavors on the lattice. This model is expected to have an infrared fixed point at high coupling. We… Expand
