In this review article, we discuss the distinction and possible equivalence between scale invariance and conformal invariance in relativistic quantum field theories. Under some …

We study the constraints of crossing symmetry and unitarity in general 3D conformal field theories. In doing so we derive new results for conformal blocks appearing in four-point …
A bstract We consider several aspects of unitary higher-dimensional conformal field theories (CFTs). We first study massive deformations that trigger a flow to a gapped phase. Deep …
In an arbitrary unitary 4D CFT we consider a scalar operator ϕ, and the operator ϕ 2 defined as the lowest dimension scalar which appears in the OPE ϕ× ϕ with a nonzero coefficient …

We study observables in a conformal field theory which are very closely related to the ones used to describe hadronic events at colliders. We focus on the correlation functions of the …
A bstract We study the conformal bootstrap for 3D CFTs with O (N) global symmetry. We obtain rigorous upper bounds on the scaling dimensions of the first O (N) singlet and …

We introduce the topic of dynamical breaking of the electroweak symmetry and its link to unparticle physics and cosmology. The knowledge of the phase diagram of strongly coupled …
In this note we discuss the relation between the constraints imposed by causality in the bulk of AdS and the condition of positivity of the energy measured in ideal calorimeters in a …
A bstract We construct the general effective field theory of gravity coupled to the Standard Model of particle physics, which we name GRSMEFT. Our method allows the systematic …
