Improved π 0 , η, η′ transition form factors in resonance chiral theory and their a μ HLbL $$ {a}_{\mu}^{\textrm{HLbL}} $$ contribution
Abstract Working with Resonance Chiral Theory, within the two resonance multiplets saturation scheme, we satisfy leading (and some subleading) chiral and asymptotic QCD constraints and accurately fit simultaneously the π 0 , η, η′ transition form factors, for single and double virtuality. In the lat...
