Nonperturbative corrections to soft drop jet mass

open access: yes, 2020
We provide a quantum field theory based description of the nonperturbative effects from hadronization for soft drop groomed jet mass distributions using the soft- collinear effective theory and the coherent branching formalism.

Squeezing, chaos and thermalization in periodically driven quantum systems: the case of bosonic preheating

open access: yesJournal of High Energy Physics
The phenomena of Squeezing and chaos have recently been studied in the context of inflation. We apply this formalism in the post-inflationary preheating phase.

Deconstruction of the Anisotropic Magnetic Interactions from Spin‐Entangled Optical Excitations in van der Waals Antiferromagnets

open access: yesAdvanced Science, Volume 13, Issue 2, 9 January 2026.
A self‐consistent ab initio many‐body perturbation theory combined with locally exact dynamical mean field theory is employed to compute the sub‐bandgap electronic transitions in van der Waals antiferromagnets. The rich interplay between the magnetic ordering and spin‐entangled optical transitions, manifested as photoluminescence and absorption ...

Non-perturbative effects in μ → eγ

open access: yesJournal of High Energy Physics, 2019
We compute the non-perturbative contribution of semileptonic tensor operators q ¯ σ μ ν q ℓ ¯ σ μ ν ℓ $$ \left(\overline{q}{\sigma}^{\mu \nu }q\right)\left(\overline{\ell}{\sigma}_{\mu \nu}\ell \right) $$ to the purely leptonic process μ → eγ and to the ...

An Overview of Scale Invariance in Proton Structure With Holographic Insights

open access: yesAdvances in High Energy Physics, Volume 2026, Issue 1, 2026.
The concept of self‐similarity in the internal structure of the proton, rooted in scale invariance and fractal geometry, provides an intriguing framework for understanding the behavior of parton distribution functions (PDFs), particularly in the small x region probed in deep inelastic scattering (DIS).

The Purely Leptonic and Semileptonic Decays of Ds∗ Meson

open access: yesAdvances in High Energy Physics, Volume 2026, Issue 1, 2026.
With the potential prospects of the Ds∗ at high‐luminosity heavy‐flavor experiments in the future, we investigated the CKM‐favored and tree‐dominated leptonic Ds∗⟶ℓν¯ℓ,ℓ=e,μ,τ and semileptonic Ds∗⟶Mℓ′ν¯ℓ′ M=ϕ,η′,K and ℓ′=e,μ weak decays in the standard model (SM).

Anisotropic lattice with nonperturbative accuracy [PDF]

open access: yes, 2005
We determine the nonperturbative anisotropic parameter of the gauge action in the quenched approximation with less than 1 0x1.dfa38p-891ccuracy using the Sommer scale measured by the Lüscher-Weisz algorithm or smearing tech- nique.

Reconstructing S-matrix Phases with Machine Learning

open access: yesJournal of High Energy Physics
An important element of the S-matrix bootstrap program is the relationship between the modulus of an S-matrix element and its phase. Unitarity relates them by an integral equation.

Nonperturbative effects in gluodynamics at T ≥ Tc

open access: yesPhysics Letters B, 1995
Abstract Contributions to gluon thermodynamics at temperature T > 0 due to a non-perturbative background field are calculated. The free energy is written as a double series in 1 N c and the strong coupling gs. The leading order contribution due to gluon loops in the nonperturbative background field contains explicitly the expectation ...

Nonperturbative Effects and the Large-Order Behavior of Matrix Models and Topological Strings

open access: yes, 2007
This work addresses nonperturbative effects in both matrix models and topological strings, and their relation with the large-order behavior of perturbation theory.
