Description
In this talk I present our high-precision estimate for the conformal window of the interacting UV fixed point in the Litim-Sannino model.
Four loop gauge, three loop Yukawa and three loop quartic beta functions are determined both by a direct loop calculation and by generalizing existing literature results.
The UV fixed point and corresponding critical exponents are determined at N$^3$LO in the conformal expansion. Several approaches to estimate the conformal window are applied, and the phenomena behind the disappearance of the fixed point are discussed.
