Resummation of Super-Leading Logarithms. [PDF]
Physical Review Letters, 2021 Jet cross sections at high-energy colliders exhibit intricate patterns of logarithmically enhanced higher-order corrections. In particular, so-called nonglobal logarithms emerge from soft radiation emitted off energetic partons inside jets. While this is

Accurate single- and double-differential resummation of colour-singlet processes with MATRIX+RADISH: W+W− production at the LHC [PDF]
Journal of High Energy Physics, 2020 We present the combination of fully differential cross sections for colour-singlet production processes at next-to-next-to-leading order (NNLO) QCD obtained with Matrix and all-order resummation through RadISH.

European Physical Journal C: Particles and Fields, 2021 We extract the $$\varepsilon $$ ε -expansion from the recently obtained seven-loop g-expansion for the renormalization group functions of the O(N)-symmetric model.

NLL′ resummation of jet mass [PDF]
Journal of High Energy Physics, 2019 Starting from a factorization theorem in effective field theory, we present resummed results for two non-global observables: the invariant-mass distribution of jets and the energy distribution outside jets.

Large-x resummation of off-diagonal deep-inelastic parton scattering from d-dimensional refactorization [PDF]
Journal of High Energy Physics, 2020 The off-diagonal parton-scattering channels g + γ* and q + ϕ* in deep-inelastic scattering are power-suppressed near threshold x → 1. We address the next-to-leading power (NLP) resummation of large double logarithms of 1 − x to all orders in the strong ...

Resummation of quantum radiation reaction and induced polarization [PDF]
Physical Review D, 2021 In a previous paper we proposed a new method based on resummations for studying radiation reaction of an electron in a plane-wave electromagnetic field.

Fiducial qT resummation of color-singlet processes at N3LL+NNLO [PDF]
Journal of High Energy Physics, 2020 We present a framework for qT resummation at N3LL+NNLO accuracy for arbitrary color-singlet processes based on a factorization theorem in SCET. Our implementation CuTe-MCFM is fully differential in the Born kinematics and matches to large-qT fixed-order ...

NNLL resummation of Sudakov shoulder logarithms in the heavy jet mass distribution
Journal of High Energy Physics, 2023 The heavy jet mass event shape has large perturbative logarithms near the leading order kinematic threshold at ρ = 1 3 $$ \rho =\frac{1}{3} $$ . Catani and Webber named these logarithms Sudakov shoulders and resummed them at double-logarithmic level.

Resummation of massive gravity. [PDF]
Physical Review Letters, 2010 We construct four-dimensional covariant nonlinear theories of massive gravity which are ghost-free in the decoupling limit to all orders. These theories resum explicitly all the nonlinear terms of an effective field theory of massive gravity.

Resummation of QED radiative corrections in a strong constant crossed field [PDF]
, 2020 By considering radiative corrections of up to 3rd-loop order, Ritus and Narozhny conjectured that the proper expansion parameter for QED in a strong constant crossed field is $g=\alpha\chi^{2/3}$, where the dynamical quantum parameter $\chi=e\sqrt{-(Fp ...
