Zoltan Fodor


Prof. Zoltan Fodor received his PhD from the Eotvos Lorand University Budapest. His early career included several years of research at CERN (Geneva, Switzerland), DESY (Hamburg, Germany), KEK (Tsukuba, Japan) and Eotvos Lorand University (Budapest, Hungary). In 1998 he became a professor at the Lorand Eotvos University, Budapest, Hungary. In 2003 he moved to the University of Wuppertal, Germany. In 2020 he joined the Pennsylvania State University, USA. Since 2005 he has been the spokesperson of the Budapest-Marseille-Wuppertal (BMW) Collaboration.

Research highlights

Ab initio calculation of the hadronic vacuum polarization contribution to the muon's magnetic moment. 

The sub-percent precision result of the BMW Collaboration is in good agreement with experimental findings.


Allowed region for axion masses


Determining the topological susceptibility in the early universe at hightemperatures gives a hint for axion masses.


Ab initio calculation of the neutron-proton mass difference


We determined the neutron-proton mass difference with an accuracy of 0.3 MeV. This figure shows this neutron-proton mass difference as a function of two fundamental parameters of nature: 


the fine structure constant and the difference between up and down quark masses.

Full result for the QCD equation of state with 2+1 flavors


Entropy and energy density of the strongly interacting matter as a function 


of the temperature. The insert shows the speed of sound.

Ab-initio determination of light hadron masses


The light hadron spectrum of QCD. Horizontal lines and bands are the experimental values with their decay widths. Our results on the masses are shown by solid circles.
