In this work we study the axial contributions to the hadronic light-by-light piece of the muon
anomalous magnetic moment. We point out some theoretical ambiguities in previous …

We have studied the one-meson radiative tau decays τ - → ν τ π - ( K - ) γ , computing the
structure-dependent contributions within a Lagrangian approach based on the large- N C limit …

We analyze the second-class current decays τ - → π - η ( ′ ) ν τ in the framework of chiral
perturbation theory with resonances. Taking into account π 0 - η - η ′ mixing, the π - η ( ′ ) …

BACKGROUND: Few attempts have been made to compare bacteremic and non-bacteremic
pneumococcal pneumonia, mainly because it is difficult to gain agreement on which cases …

The prognosis of HIV infection has improved dramatically since the introduction of highly
active antiretroviral therapy (HAART). However, numerous adverse effects and limitations …

The hadronization structure of τ−→ ηπ− π0ντ decays is analyzed using Chiral Perturbation
Theory with resonances, considering only the contribution of the lightest meson resonances …

We present an evaluation of the π ± and K ± box contributions to the hadronic light-by-light
piece of the muon’s anomalous magnetic moment, a μ . The calculation of the corresponding …

We compute for the first time the τ data-driven Euclidean windows for the hadronic vacuum
polarization contribution to the muon g − 2 . We show that τ-based results agree with the …

The anomalous < V V P > Green function and related form-factors ( π 0 → γ ⁎ γ ⁎ and τ − →
X − ν τ vector form-factors, with X − = ( K K π ) − , φ − γ , ( φ V ) − ) are analyzed in this letter …

A continuum approach to quantum chromodynamics (QCD), based upon Schwinger-Dyson (SD)
and Bethe-Salpeter (BS) equations, is employed to provide a tightly constrained …
