Conformal window in SU(2) with fundamental fermions
Viljami Leino, Jarno Rantaharju, Teemu Rantalaiho +4
We present the updated results of the infrared behavior of the SU(2) 6 and 8 fundamental representation fermions. We use the gradient flow method with the Schrödinger functional bo…
Infrared fixed point of SU(2) gauge theory with six flavors
Viljami Leino, Kari Rummukainen, Joni M. Suorsa +2
We compute the running of the coupling in SU(2) gauge theory with six fermions in fundamental representation of the gauge group. We establish an infrared stable fixed point at stro…
Gravitational waves from non-Abelian gauge fields at a tachyonic transition
Anders Tranberg, Sara Tähtinen, David J. Weir
We compute the gravitational wave spectrum from a tachyonic preheating transition of a Standard Model-like SU(2)-Higgs system. Tachyonic preheating involves exponentially growing I…
Mass anomalous dimension of SU(2) using the spectral density method
Joni M. Suorsa, Viljami Leino, Jarno Rantaharju +4
SU(2) with N_f = 6 and N_f = 8 are believed to have an infrared conformal fixed point. We use the spectral density method cross referenced with the mass step scaling method to eval…
Gradient flow running coupling in SU(2) Nf=6 flavors
Viljami Leino, Teemu Rantalaiho, Kari Rummukainen +3
We present preliminary results of the running of the coupling in SU(2) gauge theory with 6 massless fundamental representation fermion flavors. We measure the coupling using the gr…
Approaching the conformal window: systematic study of the particle spectrum in SU(2) field theory with Nf=2, 4 and 6
Alessandro Amato, Teemu Rantalaiho, Kari Rummukainen +2
It is expected that SU(2) gauge theory with fundamental fermions has an infrared fixed point when is between and 10. We study the hadron spectrum and scale set…
