It  happens in 1995, toward the end of Run 1B of the Fermilab Tevatron, in the middle of a otherwise anonymous store. The CDF detector is taking good data, and the shift crew in the control room…

"This time we're shooting through a brick!" Larry Nodulman (during a discussion on the reconstruction of electrons in the CDF II detector, just refurbished with a new set of silicon microstrip layers…

An international team of high-energy physicists says the discovery of an electrically charged subatomic particle called Zc(4020) is a sign that they have begun to unveil a whole new family of four-…

These days I am trying to reconstruct some stories from my old experiment, CDF. The CDF experiment was conceived in 1979 and constructed in the early eighties at the Fermi laboratories in Batavia,…

Top scientists met at Fermi National Accelerator Laboratory, this past weekend, in the first of a series of face to face meetings which will help determine the course of particle physics in the…

The results of the LUX experiment are out - and they are negative: no dark matter signal has been spotted by the extra sensitive detector. This is a normal day for you and me, but a gloomy day for…

The Large Underground Xenon (LUX) experiment is trying to identify the nature of dark matter, an invisible substance that physicists believe is all around us, making up most of the matter in the…

Do you remember the dijet bump at 140 GeV that CDF published in March 2011 ? This was a surprising excess in the mass distribution of pairs of jets found in events containing a leptonic W boson decay…

At some point the exact number of particles in a group becomes irrelevant. But does when a collection of elements forms a "heap" ? In recent experiments using ultracold atoms, Heidelberg physicists…

Just a quick link today, to acknowledge an interesting report on the life of physics students in Greece and the present situation with Universities there. And of course, if you wish to practice your…
