متن کاملHadronic light - by - light scattering contribution to the muon g − 2 ∗
We briefly review the current status of the hadronic light-by-light scattering correction to the muon g−2. Then we present our semi-analytical evaluation of the pion-pole contribution, using a description of the pion-photonphoton form factor based on large-NC and short-distance properties of QCD. We also sketch an effective field theory approach to hadronic light-by-light scattering. In view of...
متن کامل1 99 7 KEK - TH - 530 hep - ph / 9708227 August 1997 Pseudoscalar pole terms in the hadronic light - by - light scattering contribution to muon g − 2
The pseudoscalar pole contribution is the dominant source of the O(α 3) hadronic light-by-light scattering effect in muon g − 2. We have examined this contribution taking account of the off-shell structure of the pseudoscalar-photon-photon anomaly vertex deduced from available experimental data. Our work leads to an improved estimate, −79.2 (15.4) × 10 −11 , for the total hadronic light-by-ligh...
متن کاملTheory of the Hadronic Light - by - Light Contribution to Muon g - 2
I report on the theory, recent calculations and present status of the hadronic light-by-light contribution to muon g − 2. In particular, I report on work done together with Eduardo de Rafael and Arkady Vainshtein where we get aHLbL = (10.5 ± 2.6) × 10−10 as our present result for this quantity.

متن کاملAnalysis of the Hadronic Light - by - Light Contributions to the Muon g − 2
We calculate the hadronic light-by-light contributions to the muon g−2. We use both 1/Nc and chiral counting to organize the calculation. Then we calculate the leading and next-to-leading order in the 1/Nc expansion low energy contributions using the Extended Nambu–Jona-Lasinio model as hadronic model. We do that to all orders in the external momenta and quark masses expansion. Although the had...
