Extended investigation of the twelve-flavor $\beta$-function

25 Oct 2017 Fodor Zoltan Holland Kieran Kuti Julius Nogradi Daniel Wong Chik Him

We report new results from high precision analysis of an important BSM gauge theory with twelve massless fermion flavors in the fundamental representation of the SU(3) color gauge group. The range of the renormalized gauge coupling is extended from our earlier work {Fodor:2016zil} to probe the existence of an infrared fixed point (IRFP) in the $\beta$-function reported at two different locations, originally in {Cheng:2014jba} and at a new location in {Hasenfratz:2016dou}...
