π0,η,η′ two-photon transition form factors in the holographic soft-wall model and contributions to (g−2)μ
We compute the two-photon transition form factors of the light pseudoscalar π0, η and η′ mesons in a soft-wall holographic model of QCD with a solution of the U(1)A problem. We compare the results with the experimental data in different ranges of photon virtualities. The obtained transition form fac...
