Fifty years ago physicists, pondering how particles get mass, had suggested that there is another field, but one with no direction and the same value everywhere throughout the universe. Dr. Higgs said, “If that field exists, there should be a particle that goes with it,” just as the electromagnetic field, light, has a particle, the […]
Over the last decade, measurements by the CDF and DZero collaborations of how top quarks flee the scene of the crime, the so-called “forward-backward asymmetry,” caused quite a stir as they clashed with then state-of-the-art theoretical predictions for the Tevatron. The disagreement tantalized physicists with visions of new, unexpected particles influencing the behavior of the […]
A glimpse into how we sort out the plethora of collisions we get in our physics experiments. http://news.fnal.gov/2012/07/coping-with-high-luminosity/, by Don Lincoln.
Three good reasons why Fermilab, and other physics labs, aspire for “high energy”. http://news.fnal.gov/2012/06/why-high-energy/, by Don Lincoln.
People are made of molecules. Molecules are made of atoms. Atoms are made of protons, neutrons and electrons, Protons and neutrons are made of quarks and gluons. Is that the end? http://news.fnal.gov/2012/03/and-so-ad-infinitum-smallest-of-the-small/, by Don Lincoln
