Abstract |
The last two decades have witnessed the discovery of a myriad of new and unexpected hadrons. The future holds more surprises for us, thanks to new-generation experiments. Understanding the signals and determining the properties of the states requires a parallel theoretical effort. To make full use of available and forthcoming data, a careful amplitude modeling is required, together with a sound treatment of the statistical uncertainties, and a systematic survey of the model dependencies. We review the contributions made by the Joint Physics Analysis Center to the field of hadron spectroscopy. |

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 pi 0, eta, eta ' transition form factors, for single and double virtuality. In the latter case, we supplement the few available measurements with lattice data to ensure a faithful description. Mainly due to the new results for the doubly virtual case, we improve over existing descriptions for the eta and eta '. Our evaluation of the corresponding pole contributions to the hadronic light-by-light piece of the muon g – 2 read: a μpi 0-pole=61.9 +/- 0.6-1.5+2.4x10-11, a μeta-pole=15.2 +/- 0.5-0.8+1.1x10-11 and a μeta '-pole=14.2 +/- 0.7-0.9+1.4x10-11, for a total of a μpi 0+eta+eta '-pole=91.3 +/- 1.0-1.9+3.0x10-11, where the first and second errors are the statistical and systematic uncertainties, respectively. |
