Group theory factors for Feynman diagrams [PDF]
, 1998 We present algorithms for the group independent reduction of group theory factors of Feynman diagrams. We also give formulas and values for a large number of group invariants in which the group theory factors are expressed.

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 ...

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)

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.

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 ...

Critical Phenomena and Renormalization-Group Theory [PDF]
, 2002 We review results concerning the critical behavior of spin systems at equilibrium. We consider the Ising and the general O($N$)-symmetric universality classes, including the $N\to 0$ limit that describes the critical behavior of self-avoiding walks.

European Physical Journal C: Particles and Fields, 2020 We present an improved determination of the strange quark and antiquark parton distribution functions of the proton by means of a global QCD analysis that takes into account a comprehensive set of strangeness-sensitive measurements: charm-tagged cross ...

Bootstrapping Coulomb and Higgs branch operators
Journal of High Energy Physics, 2021 We apply the numerical conformal bootstrap to correlators of Coulomb and Higgs branch operators in 4d N $$ \mathcal{N} $$ = 2 superconformal theories. We start by revisiting previous results on single correlators of Coulomb branch operators.

Seeking SUSY fixed points in the 4 − ϵ expansion
Journal of High Energy Physics, 2021 We use the 4 − ϵ expansion to search for fixed points corresponding to 2 + 1 dimensional N $$ \mathcal{N} $$ =1 Wess-Zumino models of N Φ scalar superfields interacting through a cubic superpotential. In the N Φ = 3 case we classify all SUSY fixed points
