Enhanced Nonperturbative Effects in Jet Distributions [PDF]
Physical Review Letters, 2003 We consider the triple differential distribution d\Gamma/(dE_J)(dm_J^2)(d\Omega_J) for two-jet events at center of mass energy M, smeared over the endpoint region m_J^2

More analytic bootstrap: nonperturbative effects and fermions [PDF]
Journal 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.

ON THE NATURE OF NONPERTURBATIVE EFFECTS IN STABILIZED 2-D QUANTUM GRAVITY [PDF]
Modern Physics Letters A, 1994 We remark that the weak coupling regime of the stochastic stabilization of 2D quantum gravity has a unique perturbative vacuum, which does not support instanton configurations.

Enhanced nonperturbative effects inZdecays to hadrons [PDF]
, 2004 We use soft collinear effective field theory (SCET) to study nonperturbative strong interaction effects in Z decays to hadronic final states that are enhanced in corners of phase space. These occur, for example, in the jet energy distribution for two jet

Nonperturbative infrared effects for light scalar fields in de Sitter space [PDF]
, 2012 We study the phi^4 scalar field theory in de Sitter space using the 2PI effective action formalism. This formalism enables us to investigate the nonperturbative quantum effects.

Nonperturbative QCD vacuum effects in nonlocal quark dynamics [PDF]
, 2001 A straightforward calculation reveals the essentially nonlocal character of the leading heavy $Q\bar{Q}$ interaction arising from nonperturbative gluon field correlations in the model of a fluctuating QCD vacuum.

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

Scattering amplitudes and electromagnetic horizons
Journal 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
Journal 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.

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