Cosmology and Fundamental Physics with the Euclid Satellite

open access: yesLiving 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

open access: yesJournal 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.

Applications of Lie ring methods to group theory [PDF]

open access: yesNonassociative algebra and its applications, 2017
This is an old article of 2000. Its aim is to illustrate how a Lie-theoretic result of Zelmanov enables one to treat various problems in group theory.

Gaudin models and multipoint cnformal blocks: general theory

open access: yesJournal of High Energy Physics, 2021
The construction of conformal blocks for the analysis of multipoint correlation functions with N > 4 local field insertions is an important open problem in higher dimensional conformal field theory.

Group Field Theories [PDF]

open access: yesProceedings of 3rd Quantum Gravity and Quantum Geometry School — PoS(QGQGS 2011), 2013
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.

A Lorentzian inversion formula for defect CFT

open access: yesJournal of High Energy Physics, 2020
We present a Lorentzian inversion formula valid for any defect CFT that extracts the bulk channel CFT data as an analytic function of the spin variable.

Gaudin models and multipoint conformal blocks. Part II. Comb channel vertices in 3D and 4D

open access: yesJournal of High Energy Physics, 2021
It was recently shown that multi-point conformal blocks in higher dimensional conformal field theory can be considered as joint eigenfunctions for a system of commuting differential operators.

Group ramsey theory

open access: yesJournal 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.
