Mean field approximation for effective theories of lattice QCD

, 2022
For the exploration of the phase diagram of QCD, effective Polyakov loop theories derived from lattice QCD provide a valuable tool in the heavy quark mass regime.

Tensor meson pole contributions to the HLbL piece of $${a}_{\mu }^{\text{HLbL}}$$ within RχT

Journal of High Energy Physics
We compute the tensor meson pole contributions to the Hadronic Light-by-Light piece of a μ in the purely hadronic region, using Resonance Chiral Theory. Given the differences between the dispersive and holographic groups determinations and the resulting ...

Exploring Efimov states in D * D * D * and DD * D * three-body systems

Journal of High Energy Physics
The Efimov effect is an intriguing three-body quantum phenomenon. Searching for Efimov states within the realms of nuclear and hadronic physics presents a challenge due to the inherent inability of natural physical systems to exhibit adjustable two-body ...

Towards an effective theory of small-x QCD

, 1997
In this talk I describe recent progress in investigating the high energy limit of perturbative QCD. I review some of the steps that have been done in the direction of constructing an effective field theory for this limit.

Probing leptophobic dark sector with a pseudoscalar portal in the NA64 experiment at CERN

Journal of High Energy Physics
We propose the possibility of discovering a light pseudoscalar particle a, axion-like particle (ALP), interacting mainly with quarks using the electron and photon scattering reaction chain e + Z → e + γ + Z; γ + Z → a + Z on nuclei in the NA64 experiment

Off-lightcone Wilson-line operators in gradient flow

Journal of High Energy Physics
Off-lightcone Wilson-line operators are constructed using local operators connected by time-like or space-like Wilson lines, which ensure gauge invariance. Off-lightcone Wilson-line operators have broad applications in various contexts.

Two loop integrals and QCD scattering [PDF]

, 2001
We present the techniques for the calculation of one- and two-loop integrals contributing to the virtual corrections to 2→2 scattering of massless particles.

Computing the UV-finite electromagnetic corrections to the hadronic vacuum polarization in the muon (g − 2) from lattice QCD

Journal of High Energy Physics
In order to reach a precision of 0.2% on the hadronic vacuum polarization (HVP) contribution to the anomalous magnetic moment of the muon, (g – 2) μ , such that the full Standard-Model prediction matches in precision the direct experimental measurement ...

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,
