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.

Instanton Corrections to Quark Form Factor at Large Momentum Transfer [PDF]

, 2002
Within the Wilson integral formalism, we discuss the structure of nonperturbative corrections to the quark form factor at large momentum transfer analyzing the infrared renormalon and instanton effects.

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.

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 ...

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.

Nonperturbative and perturbative aspects of photo- and electroproduction of vector mesons [PDF]

, 2006
We discuss various aspects of vector meson production, first analysing the interplay between perturbative and nonperturbative aspects of the QCD calculation.

Topology in full QCD at high temperature: a multicanonical approach

Journal of High Energy Physics, 2018
We investigate the topological properties of N f = 2 + 1 QCD with physical quark masses, at temperatures around 500 MeV. With the aim of obtaining a reliable sampling of topological modes in a regime where the fluctuations of the topological charge Q are

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.
