Apparently scientists are having a tough time with the Higgs Boson. From Science Recorder:
According to a news release from Harvard University, Harvard and Yale scientists have made the most precise measurements ever of the shape of electrons and, as a result, have raised “severe” doubts about several popular theories of what lies beyond the Higgs boson.
“We are trying to glimpse in the lab any difference from what is predicted by the Standard Model, like what is being attempted at the LHC,” said John Doyle, Professor of Physics at Harvard, in a statement.
“It is unusual and satisfying that the exquisite precision achieved by our small team in its university lab probes the most fundamental building block of our universe at a sensitivity that compliments what is being achieved by thousands at the world’s largest accelerator,” added Gerald Gabrielse, the George Vasmer Leverett Professor of Physics at Harvard.
