Emergent symmetry in Brownian SYK models and charge dependent scrambling

open access: yesJournal 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]

open access: yes, 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

open access: yesJournal 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.

Asymptotic charges, large gauge transformations and inequivalence of different gauges in external current QED

open access: yesJournal of High Energy Physics, 2019
In this paper we consider external current QED in the Coulomb gauge and in axial gauges for various spatial directions of the axis. For a non-zero electric charge of the current, we demonstrate that any two different gauges from this class correspond to ...

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

open access: yesJournal 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 ...

Effects of nonperturbative improvement in quenched hadron spectroscopy [PDF]

open access: yesNuclear Physics B - Proceedings Supplements, 1999
We discuss a comparative analysis of unimproved and nonperturbatively improved quenched hadron spectroscopy, on a set of 104 gauge configurations, at beta=6.2. We also present here our results for meson decay constants, including the constants f_D and f_Ds in the charm-quark region.

Tunnelling of charged particles from black holes

open access: yesJournal 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.
