4d N = 3 $$ \mathcal{N}=3 $$ indices via discrete gauging
A class of 4d N = 3 $$ \mathcal{N}=3 $$ SCFTs can be obtained from gauging a discrete subgroup of the global symmetry group of N = 4 $$ \mathcal{N}=4 $$ Super Yang-Mills theory.

On Higgs decays to hadrons and the R-ratio at N4LO
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.

Group theory analysis of phonons in two-dimensional transition metal dichalcogenides [PDF]
Transition metal dichalcogenides (TMDCs) have emerged as a new two-dimensional material’s field since the monolayer and few-layer limits show different properties when compared to each other and to their respective bulk materials.

Group field theories are particular quantum field theories defined on D copies of a group which reproduce spin foam amplitudes on a space-time of dimension D. In these lecture notes, we present the general construction of group field theories, merging ideas from tensor models and loop quantum gravity. This lecture is organized as follows.

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.

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)

Group theory for structural analysis and lattice vibrations in phosphorene systems [PDF]
Group theory analysis for two-dimensional elemental systems related to phosphorene is presented, including (i) graphene, silicene, germanene, and stanene; (ii) their dependence on the number of layers; and (iii) their two possible stacking arrangements ...

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
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 ...

Superconformal boundaries in 4 − ϵ dimensions
Boundaries in three-dimensional N $$ \mathcal{N} $$ = 2 superconformal theories may preserve one half of the original bulk supersymmetry. There are two possibilities which are characterized by the chirality of the leftover supercharges.
