Nonperturbative versus perturbative effects in generalized parton distributions [PDF]

, 2004
Generalized parton distributions (GPDs) are studied at the hadronic (nonperturbative) scale within different assumptions based on a relativistic constituent quark model.

Emergent symmetry in Brownian SYK models and charge dependent scrambling

Journal of High Energy Physics, 2022
In this work, we introduce a symmetry-based approach to study the scrambling and operator dynamics of Brownian SYK models at large finite N and in the infinite N limit.

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.

Stabilization of 2D Quantum Gravity by branching interactions [PDF]

, 1995
In this paper the stabilization of 2D quantum Gravity by branching interactions is considered. The perturbative expansion and the first nonperturbative term of the stabilized model are the same than the unbounded matrix model which define pure Gravity ...

Regularization in nonperturbative extensions of effective field theory

Physical Review D, 2022
The process of renormalisation in nonperturbative Hamiltonian Effective Field Theory (HEFT) is examined in the $Δ$-resonance scattering channel. As an extension of effective field theory incorporating the Lüscher formalism, HEFT provides a bridge between the infinite-volume scattering data of experiment and the finite-volume spectrum of energy ...

Quantum distillation of Hilbert spaces, semi-classics and anomaly matching

Journal of High Energy Physics, 2018
A symmetry-twisted boundary condition of the path integral provides a suitable framework for the semi-classical analysis of nonperturbative quantum field theories (QFTs), and we reinterpret it from the viewpoint of the Hilbert space. An appropriate twist

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 ...

Borel and Stokes Nonperturbative Phenomena in Topological String Theory and c=1 Matrix Models [PDF]

, 2009
We address the nonperturbative structure of topological strings and c=1 matrix models, focusing on understanding the nature of instanton effects alongside with exploring their relation to the large-order behavior of the 1/N expansion.
