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 ...

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 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 ...

Effects of Nonperturbative Improvement in Quenched Hadron Spectroscopy [PDF]

Nuclear Physics B - Proceedings Supplements, 1998
We discuss a comparative analysis of unimproved and nonperturbatively improved quenched hadron spectroscopy, on a set of 104 gauge configurations, at beta=6.2.

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.

Nonperturbative QCD Vacuum Effects in Nonlocal Quark Dynamics [PDF]

Physical Review D, 1997
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.

Quantum effective actions from nonperturbative worldline dynamics [PDF]

Journal of High Energy Physics, 2005
We demonstrate the feasibility of a nonperturbative analysis of quantum field theory in the worldline formalism with the help of an efficient numerical algorithm. In particular, we compute the effective action for a super-renormalizable field theory with

Enhanced Nonperturbative Effects in Z Decays to Hadrons

Physical Review D, 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
