Oxidation = group theory [PDF]

Classical and Quantum Gravity, 2002
Dimensional reduction of theories involving (super-)gravity gives rise to sigma models on coset spaces of the form G/H, with G a non-compact group, and H its maximal compact subgroup.

Almost group theory

Journal of Algebra, 2015
The notion of almost centralizer and almost commutator are introduced and basic properties are established. They are used to study $\widetilde{\mathfrak M}\_c$-groups, i.

The group theory of oxidation [PDF]

Nuclear Physics B, 2002
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

Testability in group theory

Israel Journal of Mathematics, 2023
AbstractThis paper is a journal counterpart to [5], in which we initiate the study of property testing problems concerning a finite system of relations E between permutations, generalizing the study of stability in permutations. To every such system E, a group Γ = ΓE is associated and the testability of E depends only on Γ (just like in Galois theory ...

The Coulomb and Higgs branches of N $$ \mathcal{N} $$ = 1 theories of Class S k $$ {\mathcal{S}}_k $$

Journal of High Energy Physics, 2021
Even though for generic N $$ \mathcal{N} $$ = 1 theories it is not possible to separate distinct branches of supersymmetric vacua, in this paper we study a special class of N $$ \mathcal{N} $$ = 1 SCFTs, these of Class S k $$ {\mathcal{S}}_k $$ for which

Towards double parton distributions from first principles using Large Momentum Effective Theory

Journal of High Energy Physics, 2023
In double parton scattering (DPS), two partonic collisions take place between one pair of colliding hadrons. The effect of DPS can be significant for precision measurements due to the additional radiation from secondary partonic collisions, and ...

One-loop jet functions by geometric subtraction

Journal of High Energy Physics, 2020
In factorization formulae for cross sections of scattering processes, final-state jets are described by jet functions, which are a crucial ingredient in the resummation of large logarithms.

The Hopf algebra structure of the R∗-operation

Journal of High Energy Physics, 2020
We give a Hopf-algebraic formulation of the R ∗ -operation, which is a canonical way to render UV and IR divergent Euclidean Feynman diagrams finite. Our analysis uncovers a close connection to Brown’s Hopf algebra of motic graphs.

Discrete symmetries and efficient counting of operators

Journal of High Energy Physics, 2023
We present DECO (“Discrete and Efficient Counting of Operators”), an implementation of the Hilbert series to enumerate subleading operator bases for SMEFT-like EFTs with symmetry groups as typically found in flavour and BSM physics.

Trinion conformal blocks from topological strings

Journal of High Energy Physics, 2020
In this paper we investigate the relation between conformal blocks of Liouville CFT and the topological string partition functions of the rank one trinion theory T 2.
