Up to now \, the only known ultraviolet complete theories where conformal symmetry c an be spontaneously broken were associated with supersymmetry\, with the m ost prominent example being the N =4 SYM. Interestingly\, its non-supersym metric descendant\, the "Fishnet theory\," supports at the classical level a rich set of flat directions along which conformal symmetry is spontaneo usly broken. At least perturbatively\, some of these vacua survive in the full quantum theory - in the planar limit - without any finetuning. As a r esult\, the vacuum energy vanishes along these flat directions\, providing the first non-supersymmetric example of a four-dimensional quantum field theory with "natural" breaking of conformal symmetry.\n LOCATION:https://researchseminars.org/talk/CCTP_HEP/43/ END:VEVENT END:VCALENDAR
