Nonperturbative effects from the resummation of perturbation theory [PDF]
Physical Review D, 2002 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 ...

Revealing Nonperturbative Effects in the SYK Model [PDF]
Theoretical and Mathematical Physics, 2019 In the large-N limit, we study saddle points of two SYK chains coupled by an interaction that is nonlocal in Euclidean time. We study the free model with the order of the fermionic interaction q = 2 analytically and also investigate the model with ...

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 ...

Directional dependence of the local estimation of H0 and the nonperturbative effects of primordial curvature perturbations [PDF]
, 2014 Recent measurements of the cosmic microwave background (CMB) radiation have shown an apparent tension with the present value of the Hubble parameter inferred from local observations of supernovae, which look closer, i.e.

Enhanced nonperturbative effects through the collinear anomaly. [PDF]
Physical Review Letters, 2013 We show that nonperturbative effects are logarithmically enhanced for transverse-momentum-dependent observables such as qT spectra of electroweak bosons in hadronic collisions and jet broadening at e+ e- colliders.

ON THE NATURE OF NONPERTURBATIVE EFFECTS IN STABILIZED 2-D QUANTUM GRAVITY [PDF]
, 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.

Nonperturbative effects in gluon radiation and photoproduction of quark pairs [PDF]
, 1999 We introduce a nonperturbative interaction for light-cone fluctuations containing quarks and gluons. The $\bar qq$ interaction squeezes the transverse size of these fluctuations in the photon and one does not need to simulate this effect via effective ...

Universality of nonperturbative effects in c < 1 noncritical string theory [PDF]
, 2005 Nonperturbative effects in c < 1 noncritical string theory are studied using the two-matrix model. Such effects are known to have the form fixed by the string equations but the numerical coefficients have not been calculated so far.

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.
