# New determination of the fine structure constant and test of the quantum electrodynamics

@article{Bouchendira2012NewDO, title={New determination of the fine structure constant and test of the quantum electrodynamics}, author={Rym Bouchendira and Pierre Clad{\'e} and Sa{\"i}da Guellati-Kh{\'e}lifa and François Nez and Francois Biraben}, journal={2012 Conference on Lasers and Electro-Optics (CLEO)}, year={2012}, pages={1-2} }

We report a new value of the fine structure constant with a relative uncertaintity of 6.6×10-10. This result is deduced from the h/m ratio measurement on Rb atoms. The comparison with the electron anomaly measurements reveals an agreement. Moreover, the precision is large enough to verify for the first time the muonic and hadronic contributions to this anomaly.
