Nonperturbative effects and nonperturbative definitions in matrix models and topological strings

Journal of High Energy Physics, 2008
We develop techniques to compute multi-instanton corrections to the 1/N expansion in matrix models described by orthogonal polynomials. These techniques are based on finding trans-series solutions, i.e. formal solutions with exponentially small corrections, to the recursion relations characterizing the free energy.

Nonperturbative effects in triple-differential dijet and Z+jet production at the LHC

SciPost Physics
In comparisons of precision measurements at colliders to the most accurate predictions available in perturbative quantum chromodynamics (QCD), it is required to correct for nonperturbative effects.

Nonperturbative effects in supergravity [PDF]

, 2006
A promising candidate for a fundamental theory of nature, incorporating both general relativity and quantum mechanics, is string theory. This theory is based on one-dimensional extended objects that move through spacetime. However, string theory is most naturally formulated in ten dimensions.

Scattering amplitudes from dispersive iterations of unitarity

Journal of High Energy Physics, 2023
We present and numerically implement a computational method to construct relativistic scattering amplitudes that obey analyticity, crossing, elastic and inelastic unitarity in three and four spacetime dimensions.

Theory and modeling of nonperturbative effects in thermoviscous acoustofluidics [PDF]

Physical Review E, 2023
A theoretical model of thermal boundary layers and acoustic heating in microscale acoustofluidic devices is presented. Based on it, an iterative numerical model is developed that enables numerical simulation of nonlinear thermoviscous effects due to acoustic heating and thermal advection.

Drell-Yan angular lepton distributions at small x from TMD factorization.

Journal of High Energy Physics, 2021
The Drell-Yan process is studied in the framework of TMD factorization in the Sudakov region s » Q 2 » q ⊥ 2 $$ {q}_{\perp}^2 $$ corresponding to recent LHC experiments with Q 2 of order of mass of Z-boson and transverse momentum of DY pair ∼ few tens ...

Tunnelling of charged particles from black holes

Journal of High Energy Physics, 2020
We state and explain the total rate at which a charged non-rotating black hole emits charged particles, taking into account both Hawking radiation and Schwinger pair production simultaneously.

The axion quality problem: global symmetry breaking and wormholes

Journal of High Energy Physics, 2021
Continuous global symmetries are expected to be broken by gravity, which can lead to important phenomenological consequences. A prime example is the threat that this poses to the viability of the Peccei-Quinn solution to the strong CP problem.
