Oxidation   group theory [PDF]

Classical and Quantum Gravity, 2003
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. The reverse process, called oxidation, is the reconstruction of the possible higher dimensional theories, given the lower dimensional theory. In 3 dimensions, all degrees

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 ...

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

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.

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.

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.

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.

Cosmology and Fundamental Physics with the Euclid Satellite

Living Reviews in Relativity, 2013
Euclid is a European Space Agency medium-class mission selected for launch in 2019 within the Cosmic Vision 2015-2025 program. The main goal of Euclid is to understand the origin of the accelerated expansion of the universe.

Next-to-leading power resummed rapidity distributions near threshold for Drell-Yan and diphoton production

Journal of High Energy Physics, 2023
We consider Drell-Yan production and QCD-induced diphoton production and compute their rapidity distributions up to next-to-leading power (NLP) in the threshold variable.
