Status of the hadronic light-by-light contribution to the muon anomalous magnetic moment

Presented by J. Prades at The Final EURIDICE Meeting “Effective Theories of Colours and Flavours: from EURODAPHNE to EURIDICE”, Kazimierz, Poland, 24–27 August, 2006.We review the present status of the hadronic light-by-light contribution to muon g − 2 and critically compare recent calculations.This work is supported in part by the European Commission (EC) RTN network, Contract No. MRTN-CT-2006-035482 (FLAVIAnet), the European Community Research Infrastructure Activity Contract No. RII3-CT- 2004-506078 (HadronPhysics) (J.B.), the Swedish Research Council (J.B.), MEC (Spain) and FEDER (EC) Grant No. FPA2006-05294 (J.P.), and Junta de Andalucía Grant Nos.
