RS-invariant resummations of QCD perturbation theory [PDF]
, 1997 We propose a renormalon-inspired resummation of QCD perturbation theory based on approximating the renormalization scheme (RS) invariant effective charge (EC) beta- function coefficients by the portion containing the highest power of b = (11N'-2N(_f))/6,

Advances in High Energy Physics, Volume 2026, Issue 1, 2026.The effective string tension (κ) in the Schwinger mechanism and the effective temperature (T) in Bose–Einstein statistics are extracted from the transverse momentum (pT) spectra of heavy quarkonia produced in proton‐proton (p + p) collisions at the Large Hadron Collider (LHC).

The scale dependence of perturbative QCD predictions for e+e− event shape moments and LHC observables [PDF]
, 2013 Perturbative QCD predictions that are truncated at fixed order have an unphysical dependence on the renormalisation procedure. We investigate two methods of avoiding scale and scheme dependence in QCD predictions of physical observables: the Effective ...

The hyperfine splitting in QCD mesonic screening masses at asymptotically large temperatures
Journal of High Energy PhysicsWe determine the hyperfine splitting in the QCD flavour non-singlet mesonic screening masses at asymptotically large temperatures. The analytic calculation is carried out in the dimensionally-reduced effective theory where the first non-zero contribution

Abelian decomposition and Weyl symmetric effective action of SU(3) QCD
European Physical Journal C: Particles and Fields, 2019 We show how to calculate the effective potential of SU(3) QCD which tells that the true minimum is given by the monopole condensation. To do this we make the gauge independent Weyl symmetric Abelian decomposition of the SU(3) QCD which decomposes the ...

QCD at the amplitude level: Fock state interference in heavy quark electroproduction
Journal of High Energy Physics, 2023 Quantum chromodynamics (QCD) rigorously predicts the existence of both nonperturbative intrinsic and perturbative extrinsic heavy quark contents of nucleons.

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

Perturbative QCD studies of multijet structures in electron-positron annihilation [PDF]
, 1987 To investigate the effect in perturbative QCD of multigluon emissions on the transverse momentum distributions of multijet final states in electron-positron annihilation, we use a simplified model based on the approximation that gluons are emitted ...

Recent Developments in Perturbative QCD [PDF]
, 2005 I review recent progress in perturbative QCD on two fronts: extending next-to-next-to-leading order QCD corrections to a broader range of collider processes, and applying twistor-space methods (and related spinoffs) to computations of multi-parton ...

Nuclear Physics in the Era of Quantum Computing and Quantum Machine Learning
Advanced Quantum Technologies, Volume 8, Issue 12, December 2025.The use of QML in the realm of nuclear physics at low energy is almost nonexistent. Three examples of the use of quantum computing and quantum machine in nuclear physics are presented: the determination of the phase/shape in nuclear models, the calculation of the ground state energy, and the identification of particles in nuclear physics experiments ...
