More analytic bootstrap: nonperturbative effects and fermions [PDF]

open access: yesJournal of High Energy Physics, 2019
We develop the analytic bootstrap in several directions. First, we discuss the appearance of nonperturbative effects in the Lorentzian inversion formula, which are exponentially suppressed at large spin but important at finite spin.

Determination of HQET nonperturbative matrix elements with renormalon subtraction using Fourier transform [PDF]

open access: yesEPJ Web of Conferences, 2022
As higher order perturbative series are available, it is becoming necessary to include nonperturbative effects in QCD calculations using the OPE. In order to systematically determine nonperturbative effects and to incorporate them into theoretical ...

Comment on nonperturbative effects in [PDF]

open access: yesPhysics Letters B, 1997
Abstract Uncertainties in the theoretical prediction for the inclusive B → X s γ decay rate are discussed. We emphasize that there is no operator product expansion for this process. Nonetheless, some nonperturbative effects involving a virtual c c loop are calculable using the operator product expansion.

Scattering amplitudes and electromagnetic horizons

open access: yesJournal of High Energy Physics, 2023
We consider the scattering of charged particles on particular electromagnetic fields which have properties analogous to gravitational horizons. Classically, particles become causally excluded from regions of spacetime beyond a null surface which we ...

CFT description of BH’s and ECO’s: QNMs, superradiance, echoes and tidal responses

open access: yesJournal of High Energy Physics, 2022
Using conformal field theory and localization tecniques we study the propagation of scalar waves in gravity backgrounds described by Schrödinger like equations with Fuchsian singularities.

Enhanced Nonperturbative Effects in Jet Distributions [PDF]

open access: yesPhysical Review Letters, 2003
We consider the triple differential distribution dΓ/(dE_J)(dm_J^2)(dΩ_J) for two-jet events at center of mass energy M, smeared over the endpoint region m_J^2 << M^2, |2 E_J -M| ~ Δ, \lqcd << Δ<< M. The leading nonperturbative correction, suppressed by \lqcd/Δ, is given by the matrix element of a single operator. A similar analysis is

Critical behavior of the 2d scalar theory: resumming the N8LO perturbative mass gap

open access: yesJournal of High Energy Physics, 2021
We apply the optimized perturbation theory (OPT) to resum the perturbative series describing the mass gap of the bidimensional ϕ 4 theory in the ℤ2 symmetric phase.

Emergent symmetry in Brownian SYK models and charge dependent scrambling

open access: yesJournal of High Energy Physics, 2022
In this work, we introduce a symmetry-based approach to study the scrambling and operator dynamics of Brownian SYK models at large finite N and in the infinite N limit.
