B s → Kℓν ℓ and B (s) → π(K)ℓ + ℓ − decays at large recoil and CKM matrix elements

Journal of High Energy Physics, 2017
We provide hadronic input for the B-meson semileptonic transitions to a light pseudoscalar meson at large recoil. The B s → K form factor calculated from QCD light-cone sum rule is updated, to be used for a |V ub | determination from the B s → Kℓν width.

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).

Master Integrals for the two-loop, non-planar QCD corrections to top-quark pair production in the quark-annihilation channel

Journal of High Energy Physics, 2019
We present the analytic calculation of the Master Integrals for the twoloop, non-planar topologies that enter the calculation of the amplitude for top-quark pair hadroproduction in the quark-annihilation channel.

Heavy quark potential from deformed $AdS_5$ models

, 2017
In this paper, we investigate the heavy quark potential in some holographic QCD models. The calculation relies on a modified renormalization scheme mentioned in a previous work of Albacete et al.

Analytical Description of the Distributions of Primary and Secondary Cosmogenic Particles

Advances in High Energy Physics, Volume 2026, Issue 1, 2026.
In this work, we present an analytical description of the energy distributions of primary and secondary cosmogenic particles on Earth in terms of parameters having clear physical meaning. A modified power law is assumed for energy distributions, incorporating terms such as energy loss/decay, which are effective at low energies, and a source term, which

Heavy-light meson spectrum with and without NRQCD

, 2000
Results for the spectrum of S and P-wave charmed mesons are obtained in the quenched approximation from a tadpole-improved anisotropic gauge field action and a D234 quark action.

Mass Spectra, Radii, and Decay Widths of Toponium

Advances in High Energy Physics, Volume 2026, Issue 1, 2026.
In this work, the radial Schrodinger equation with a nonrelativistic quark potential model (NRQPM) is solved numerically by employing the shooting method. Calculated numerical wave functions (or solutions) are used to compute the masses, root mean square (RMS) radii, E1, M1 radiative transition widths, annihilation decay widths, and branching ratios of

Neural network modeling of heavy-quark potential from holography

European Physical Journal C: Particles and Fields
Using Multi-Layer Perceptrons (MLP) and Kolmogorov–Arnold Networks (KAN), we construct a holographic model based on lattice QCD data for the heavy-quark potential in the 2+1 system.

Impact of Neuromuscular Electrical Stimulation on Biological Markers in Critically Ill Patients: A Systematic Review and Meta‐Analysis

Critical Care Research and Practice, Volume 2026, Issue 1, 2026.
Purpose Neuromuscular electrical stimulation (NMES) has been increasingly used to preserve or restore neuromuscular function in critically ill patients. However, its effects on inflammatory biomarkers and its safety require to be fully elucidated.

Coulomb artifacts and breakdown of perturbative matching in lattice NRQCD

Journal of High Energy Physics, 2017
By studying an explicit analytical solution of the Schrödinger equation with the Coulomb potential on the lattice we demonstrate a breakdown of perturbative matching for the description of the Coulomb artifacts in lattice NRQCD, which leads to a large ...
