Journal ArticleDOI
Galileon as a local modification of gravity
TL;DR: In this article, the authors study the connection between self-acceleration and the presence of ghosts for a quite generic class of theories that modify gravity in the infrared, defined as those that at distances shorter than cosmological, reduce to a certain generalization of the Dvali-Gabadadze-Porrati (DGP) effective theory.
Journal ArticleDOI
Theories with Gauge-Mediated Supersymmetry Breaking
TL;DR: Theoretically, these theories allow for a natural suppression of flavour violations in the supersymmetric sector and have very distinctive phenomenological features as discussed by the authors, and the experimental implications of these theories have been discussed.
Journal ArticleDOI
Gaugino mass without singlets
TL;DR: In this paper, it was shown that there is a supergravity contribution to the quantum level of the superconformal anomaly to the A terms proportional to the beta function of the corresponding Yukawa coupling.
Journal ArticleDOI
Causality, analyticity and an IR obstruction to UV completion
Allan Adams,Nima Arkani-Hamed,Sergei Dubovsky,Sergei Dubovsky,Sergei Dubovsky,Alberto Nicolis,Riccardo Rattazzi +6 more
TL;DR: In this paper, it was shown that low-energy effective field theories described by local, Lorentz invariant Lagrangians, secretly exhibit macroscopic non-locality and cannot be embedded in any UV theory whose S-matrix satisfies canonical analyticity constraints.
Journal ArticleDOI
Bounding scalar operator dimensions in 4D CFT
TL;DR: In this article, a theory-independent inequality [phi(2)] 1 was derived for 4D conformal fixed points, where f(d) = 2 + O(root d - 1), which shows that the free theory limit is approached continuously.
