Constraints on Perturbative RG Flows in Six Dimensions
Andreas Stergiou, David Stone, Lorenzo G. Vitale
When conformal field theories (CFTs) are perturbed by marginally relevant deformations, renormalization group (RG) flows ensue that can be studied with perturbative methods, at lea…
Two-loop renormalization of multiflavor theory in six dimensions and the trace anomaly
Benjamin Grinstein, Andreas Stergiou, David Stone +1
We use the background-field method and the heat kernel to obtain all counterterms to two-loop order of conformally-coupled multiflavor theory in six spacetime dimensions, def…
A challenge to the -theorem in six dimensions
Benjamin Grinstein, Andreas Stergiou, David Stone +1
The possibility of a strong -theorem in six dimensions is examined in multi-flavor theory. Contrary to the case in two and four dimensions, we find that in perturbation th…
decays to two pseudoscalars and a generalized rule
Benjamín Grinstein, David Pirtskhalava, David Stone +1
We perform an isospin analysis of decays to two pseudoscalars. The analysis extracts appropriate CKM and short distance loop factors to allow for comparison of non-perturbative…
Consequences of Weyl Consistency Conditions
Benjamin Grinstein, Andreas Stergiou, David Stone
The running of quantum field theories can be studied in detail with the use of a local renormalization group equation. The usual beta-function effects are easy to include, but by i…
Spontaneous R-symmetry breaking from the renormalization group flow
Antonio Amariti, David Stone
We propose a mechanism of R-symmetry breaking in four-dimensional DSB models based on the RG properties of the coupling constants. By constraining the UV sector, we generate new hi…
Explaining the ttbar Forward-Backward Asymmetry from a GUT-Inspired Model
David C. Stone, Patipan Uttayarat
We consider a model that includes light colored scalars from the {\bf 45} and {\bf 50} representations of SU(5) in order to explain the CDF- and D-reported forward-ba…
