The Purely Leptonic and Semileptonic Decays of Ds∗ Meson
Advances 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).

Advances in High Energy Physics, Volume 2026, Issue 1, 2026.We present an analytical investigation of the creation of neutral scalar particle–antiparticle pair in the spacetime of a cosmic string under the combined influence of Coulomb‐type interactions and a KG‐oscillator–type nonminimal coupling. The scalar field is described by a modified Klein–Gordon equation including scalar, minimally coupled vector, and ...

Nonperturbative electron-ion scattering theory incorporating the Møller interaction [PDF]
, 2014 We present the first calculations that investigate the effects of both the Møller interaction and close-coupling in the calculation of electron-impact excitation cross sections. Electron scattering from U 91+ is used as a test case.

Nonperturbative phenomena in semiconductor four-wave mixing spectra [PDF]
, 2009 Nonperturbative phenomena in four-wave mixing spectra of semiconductors are studied using the exact solution of a widely used phenomenological nonlinear equation of motion of the exciton polarization. It is shown that the Coulomb interaction, included in

Journal of Applied Mathematics, Volume 2026, Issue 1, 2026.This study involves the development of a framework for checking the accuracy of built‐in algorithms from Mathcad software. The built‐in algorithms used inside Mathcad software include Runge–Kutta method of the fourth order (RK4), Adams method, backward differential formula, AdamsBDF, Radau, Bulstoer, Stiffr, and Stiffb methods.

Elliptic genus derivation of 4d holomorphic blocks
Journal of High Energy Physics, 2018 We study elliptic vortices on ℂ × T 2 by considering the 2d quiver gauge theory describing their moduli spaces. The elliptic genus of these moduli spaces is the elliptic version of vortex partition function of the 4d theory. We focus on two examples: the

Large-order behavior and nonperturbative effects [PDF]
Nuclear Physics B, 1995 Abstract We consider the energy-dependence of the large-order behavior of forward scattering amplitudes in theories having explicit mass parameters and instanton solutions. We show that in weak coupling theories the exponential part of the Espinosa-Ringwald type cross section can be determined by taking the minimum element of the perturbative series,

Nonperturbative Effects in Energy Correlators: From Characterizing Confinement Transition to Improving $\alpha_s$ Extraction [PDF]
Energy correlators provide a powerful observable to study fragmentation dynamics in QCD. We demonstrate that the leading nonperturbative corrections for projected $N$-point energy correlators are described by the same universal parameter for any $N ...
