Enhanced nonperturbative effects in jet distributions [PDF]

Physical Review Letters, 2002
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

Nonperturbative effects of divergent ghost loops [PDF]

Acta Physica Polonica B Proceedings Supplement, 2014
We report on a recently unveiled connection at the nonperturbative level between the masslessness of the ghost, the precise form of the gluon propagator in the deep infrared, and the divergences observed in certain kinematic limits of the three-gluon ...

Nonperturbative Effects from the Resummation of Perturbation Theory [PDF]

Physical Review D, 2001
Using the general argument in Borel resummation of perturbation theory that links the divergent perturbation theory to the nonperturbative effect we argue that the nonperturbative effect associated with the perturbation theory should have a branch cut ...

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.

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 ...

Helically Magnetized Plasma: From Photonic Fermi-Arc Metal to Chirality-Free Uniaxial Medium. [PDF]

Nanophotonics
A helically modulated magnetic field in magnetized plasma realizes a photonic Fermi‐arc metal, enabling full analytical tracking of Weyl node evolution. As modulation strengthens, opposing‐chirality Fermi arcs hybridize and recombine, yielding a chirality‐free uniaxial optical medium without conventional node annihilation.

Density-functional tight binding meets Maxwell: unraveling the mysteries of (strong) light-matter coupling efficiently. [PDF]

Nanophotonics
Abstract Controlling chemical and material properties through strong light–matter coupling in optical cavities has gained considerable attention over the past decade. However, the underlying mechanisms remain insufficiently understood, and a significant gap persists between experimental observations and theoretical descriptions.

Comment on nonperturbative effects in [PDF]

Physics 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.
