Journal of High Energy Physics, 2020 We present a mechanism for realizing hybrid inflation using two axion fields with a purely non-perturbatively generated scalar potential. The structure of the scalar potential is highly constrained by the discrete shift symmetries of the axions.

Journal of High Energy Physics, 2017 Applications of the bootstrap program to superconformal field theories promise unique new insights into their landscape and could even lead to the discovery of new models.

Journal of High Energy Physics, 2023 Pions of a dark sector gauge group can be strongly interacting massive particle (SIMP) dark matter, produced by the freeze-out of 3 → 2 interactions, with naturally large self-interactions. We study if adding a dark photon to the set-up can do it all: i)

Higher-order Sudakov resummation in coupled gauge theories
Journal of High Energy Physics, 2020 We consider the higher-order resummation of Sudakov double logarithms in the presence of multiple coupled gauge in. The associated evolution equations depend on the coupled β functions of two (or more) coupling constants α a and α b , as well as ...

Bootstrapping the (A1, A2) Argyres-Douglas theory
Journal of High Energy Physics, 2018 We apply bootstrap techniques in order to constrain the CFT data of the (A 1 , A 2) Argyres-Douglas theory, which is arguably the simplest of the Argyres-Douglas models.

Bootstrapping line defects with O(2) global symmetry
Journal of High Energy Physics, 2022 We use the numerical bootstrap to study conformal line defects with O(2) global symmetry. Our results are very general and capture in particular conformal line defects originating from bulk CFTs with a continuous global symmetry, which can either be ...

European Physical Journal C: Particles and Fields, 2020 We present an improved determination of the strange quark and antiquark parton distribution functions of the proton by means of a global QCD analysis that takes into account a comprehensive set of strangeness-sensitive measurements: charm-tagged cross ...

, 2011 The ordinary formalism for classical field theory is applied to dynamical group field theories. Focusing first on a local group field theory over one copy of SU(2) and, then, on more involved nonlocal theories (colored and non colored) defined over a ...

Bootstrapping Coulomb and Higgs branch operators
Journal of High Energy Physics, 2021 We apply the numerical conformal bootstrap to correlators of Coulomb and Higgs branch operators in 4d N $$ \mathcal{N} $$ = 2 superconformal theories. We start by revisiting previous results on single correlators of Coulomb branch operators.

Apollonian Circle Packings: Geometry and Group Theory I. The Apollonian Group [PDF]
, 2005 Apollonian circle packings arise by repeatedly filling the interstices between four mutually tangent circles with further tangent circles. We observe that there exist Apollonian packings which have strong integrality properties, in which all circles in ...
