During the past week there’s been a lot of talk about Theoretical Physics at the University of California Irvine analyzing data from the Institute for Nuclear Research at Debrecen Hungary, some news articles have even called the UC Irvine analysis a conformation. What’s all this about.
First of all, a little background. Modern Physics recognizes four Forces of nature: Gravity, Electromagnetism and two Forces that only work over the immensely short nuclear distances. These are called the Strong (or color) force and the Weak force.
For nearly forty years now physicists have been looked for something beyond the standard model of particles and forces because the standard model cannot describe gravity at the nuclear scale, nor does it describe the motions of galaxies attributed to “Dark Matter” nor finally the accelerated expansion of the universe attributed to “Dark Energy”.
Now, what the researchers in Hungary were doing was to take nuclei of Lithium and bombard them with energetic protons turning them into nuclei of Beryllium in an excited state, excited state in important. The excited Beryllium nuclei would then sometimes decay into Beryllium in the ground state by emitting a gamma ray photon (a very high energy particle of light) and the gamma ray would then split into an electron-positron pair.
Measuring the energy spectrum of the gamma rays the group in Hungary found a bump at an energy of 17 million electron volts that could be due to a particle other than the gamma photons, an unknown particle. The theoreticians at UC Irvine then looked at the Hungarian data and determined that the new particle would be a force carrying Boson. The data implied not just a new particle but a new force.
First of all, the work at UC Irvine is not a conformation it is an analysis. Conformation requires another laboratory to replicate the data from Hungary. Fortunately the energy levels involved are low enough to allow many laboratories to do the experiment and confirm the Hungarian’s work, or otherwise. we should have an answer soon, a year or so.
This is the fourth time in my career someone has announced a fifth force and each time previously the new force quickly disappeared when subject to additional scrutiny. I’m hopeful, because a new force would be really cool, and I’ll keep reading the published articles, but I’m not holding my breath.
