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 ...

Journal of Combinatorial Theory, Series A, 1974 AbstractA subset S of a group G is said to be a sum-free set if S ∩ (S + S) = ⊘. Such a set is maximal if for every sum-free set T ⊆ G, we have |T| ⩽ |S|. Here, we generalize this concept, defining a sum-free set S to be locally maximal if for every sum free set T such that S ⊆ T ⊆ G, we have S = T.

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.

The group theory of oxidation [PDF]
Nuclear Physics B, 2003 Dimensional reduction of (super-)gravity theories to 3 dimensions results in sigma models on coset spaces G/H, such as the E_8/SO(16) coset in the bosonic sector of 3 dimensional maximal supergravity. The reverse process, oxidation, is the reconstruction of a higher dimensional gravity theory from a coset sigma model.

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 ...

Five-loop renormalisation of QCD in covariant gauges
Journal of High Energy Physics, 2017 We present the complete set of vertex, wave function and charge renormalisation constants in QCD in a general simple gauge group and with the complete dependence on the covariant gauge parameter ξ in the minimal subtraction scheme of conventional ...

Seeking SUSY fixed points in the 4 − ϵ expansion
Journal of High Energy Physics, 2021 We use the 4 − ϵ expansion to search for fixed points corresponding to 2 + 1 dimensional N $$ \mathcal{N} $$ =1 Wess-Zumino models of N Φ scalar superfields interacting through a cubic superpotential. In the N Φ = 3 case we classify all SUSY fixed points

Four-loop QCD propagators and vertices with one vanishing external momentum
Journal of High Energy Physics, 2017 We have computed the self-energies and a set of three-particle vertex functions for massless QCD at the four-loop level in the M S ¯ $$ \overline{\mathrm{MS}} $$ renormalization scheme.

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.
