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)

On Higgs decays to hadrons and the R-ratio at N4LO
Journal of High Energy Physics, 2017 We present the first determination of Higgs-boson decay to hadrons at the next-to-next-to-next-to-next-to-leading order of perturbative QCD in the limit of a heavy top quark and massless light flavours.

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.

Character groups of Metacyclic groups [PDF]
arXiv, 2023 Pontryagin duality provides a powerful tool for analyzing the structure and properties of locally compact abelian groups, in particular finite abelian groups. Now much can be done with non-abelian groups via the construction of character groups. In this paper we provide a set of conditions a group must satisfy to be realized as a balanced character ...

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.

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.

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 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 ...

Linearity of Generalized Cactus Groups [PDF]
arXiv, 2022 Cactus groups are traditionally defined based on symmetric groups, and pure cactus groups are particular subgroups of cactus groups. Mostovoy showed that pure cactus groups embed into right-angled Coxeter groups. We generalize this result to cactus groups associated with arbitrary finite Coxeter groups and we investigate some representations of ...

A theory of semiprimitive groups [PDF]
Journal of Algebra, 2018 A transitive permutation group is semiprimitive if each of its normal subgroups is transitive or semiregular. Interest in this class of groups is motivated by two sources: problems arising in universal algebra related to collapsing monoids and the graph-restrictive problem for permutation groups.
