Calibrated correlation between heavy-quark masses and Hadronic Vacuum Polarization observables at the precision frontier
Arnau Beltran, Pere Masjuan, Antonio Rivera
The theoretical prediction of the muon anomalous magnetic moment depends crucially on the Hadronic Vacuum Polarization (HVP), and the tension between its dispersive and latti…
Analytically Consistent Reconstruction of Finite Data Using Padé Sequences
Emerson Díaz, Balma Duch, Pere Masjuan
Reconstructing the analytic structure of a function from finite datasets is a fundamental problem across theoretical, numerical, and experimental physics. While Padé approximants p…
Correlated low-energy constants in large- chiral perturbation theory
Pere Masjuan
The combined chiral and large- expansion is increasingly employed in precision studies involving the and mesons, including recent applications to low-energy axion phe…
Phenomenology of a double dilaton soft-wall model: Alpha strong from Ricci flow and pion Form Factors at intermediate-energy region
Héctor Cancio, Pere Masjuan
Through a holographic model of QCD, we present a phenomenological approach to study the running of the strong coupling constant α_s in both non-perturbative and perturbative regim…
Box at Low Energy
Balma Duch, Pere Masjuan, Hubert Spiesberger
We calculate the 1-loop box-graph correction to electron-quark scattering at low energy and low momentum transfer. Both electron and quark masses are kept non-zero. From our…
From QCD-Based Descriptions to Direct Fits: A Unified Study of Nucleon Electromagnetic Form Factors
Hossein Vaziri, Mohammad Reza Shojaei, Pere Masjuan
We present a detailed study of the nucleon electromagnetic form factors in the spacelike region by combining three complementary approaches: two GPD-based contributions and a vecto…
