Asymptotic Safety Guaranteed at Four Loop
Daniel F. Litim, Nahzaan Riyaz, Emmanuel Stamou +1
We investigate a family of four-dimensional quantum field theories with weakly interacting ultraviolet fixed points up to four loop order in perturbation theory. Key new ingredient…
Scaling dimensions in QED from the -expansion
Lorenzo Di Pietro, Emmanuel Stamou
We study the fixed point that controls the IR dynamics of QED in . We derive the scaling dimensions of four-fermion and bilinear operators beyond leading order in -e…
Operator mixing in -expansion: scheme and evanescent (in)dependence
Lorenzo Di Pietro, Emmanuel Stamou
We consider theories with fermionic degrees of freedom that have a fixed point of Wilson-Fisher type in non-integer dimension . Due to the presence of evanescent operator…
Quantum Electrodynamics in d=3 from the epsilon-expansion
Lorenzo Di Pietro, Zohar Komargodski, Itamar Shamir +1
We study Quantum Electrodynamics in d=3 (QED_3) coupled to N_f flavors of fermions. The theory flows to an IR fixed point for N_f larger than some critical number N_f^c. For N_f<=…
