Lightest pseudoscalar exchange contribution to light-by-light scattering piece of the muon g-2

Pablo Roig, Adolfo Guevara, Gabriel López Castro

Lightest pseudoscalar (P= pi^0, eta, eta') exchange contribution to the light-by-light (LbL) scattering piece of the muon anomaly, a_mu=(g_mu-2)/2, has been evaluated using a reson…

$W^{} γ^{} π$ form factors in the $τ^{-} \to π^{-} ℓ^{+} ℓ^{-} ν_{τ}$ decays

Adolfo Guevara

We study the disintegration $τ^{-} \to π^{-} ℓ^{+} ℓ^{-} ν_{τ}$ , where $l$ denotes either an electron or a muon. This process requires knowledge about the $W^{*} γ^{*} π$ interaction, which is…

The VV'P form factors in resonance chiral theory and the pi-eta-eta' light-by-light contribution to the muon g-2

P. Roig, A. Guevara, G. López Castro

The description of the VV'P form factors (V,V' stands for vector particles and P for a pseudoscalar meson) for different particles virtualities remains a challenge for the theory o…
