Two-Point Functions and S-Parameter in QCD-like Theories

open access: yes, 2011
We calculated the vector, axial-vector, scalar and pseudo-scalar two-point functions up to two-loop level in the low-energy effective field theory for three different QCD-like theories. In addition we also calculated the pseudo-scalar decay constant $G_M$

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

open access: yesJournal 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 ...

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

open access: yesJournal 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

open access: yesJournal 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.

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

open access: yesJournal 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 ...
