About a year ago, the DZero collaboration at Fermilab published a tantalizing result in which the universe unexpectedly showed a preference for matter over antimatter. Now the collaboration has more data, and the evidence for this effect has grown stronger. The result is extremely exciting: The question of why our universe should exist solely of [...]

Scientists of the MINOS experiment at the Department of Energy’s Fermi National Accelerator Laboratory announced today the results from a search for a rare phenomenon, the transformation of muon neutrinos into electron neutrinos. The result is consistent with and significantly constrains a measurement reported 10 days ago by the Japanese T2K experiment, which announced an indication of this type of transformation. : Physics Without Ideology Bite by Bite The search for a theory of everything : satire about bad candidates and gentle fun about good candidates , such as the strand-spaghetti . model 24 June 2011 No electroweak unification and no electroweak interaction Why do so many people think that the electromagnetic and the weak interaction have been unified They have not .

Like particle physicists the world over, Stanford's Matt Bellis is always looking for ways to share his research with the public. "I had the idea of the BaBar detector as an instrument," Bellis said, but not one played by human hands. It would be played by the particles gusting through it, like wind through a wind chime.
A critical endpoint in QCD is a kind of holy grail in nuclear physics. It has been theorized as a point where deconfinement occurs and hadronic matter leaves place to some kind of plasma of quarks and gluons. We know that the breaking of chiral symmetry is something that people has proposed several years ago [...]
Dr. Rosalyn Sussman Yalow, who passed away last month on May 30, was a mother, wife, educator, and dedicated medical physicist. She received the Nobel Prize in Medicine in 1977 while working for the Veterans Administration Hospital in New York for her contributions to the development of radioimmunoassays of peptide hormones. Today scientists utilize this technology to further diagnostics in the medical field for cancer research and Type II diabetes.

The Japan-based experiment T2K Tuesday gave scores of U.S. particle hunters a license to ready their detectors and take aim at the biggest question in the universe: How everything we see came to exist.
As of this week, the Large Hadron Collider has delivered 1 inverse femtobarn of integrated luminosity to ATLAS and CMS, two of the four experimental stations housed along the ring. This means the detectors will have gathered data from about 70 trillion proton-proton collisions. For comparison, the experiments collected just 45 inverse picobarns in all of 2010; 1 inverse femtobarn is equal to one thousand inverse picobarns.

The origin of ultra-high-energy cosmic rays is a question that makes it onto many top-unsolved-problems-in-physics lists. Scientists are proposing a new experiment, called TAUWER, that would look to tau neutrinos to remove some of the mystery from these strange, over-stimulated cosmic rays.
Recreating the conditions present just after the Big Bang has given experimentalists a glimpse into how the universe formed. Now, scientists have begun to see striking similarities between the properties of the early universe and a theory that aims to unite gravity with quantum mechanics, a long-standing goal for physicists.
The T2K experiment in Japan has observed six particle events that indicate the oscillation of muon neutrinos into electron neutrinos, a long-sought signal that allows scientists to better understand a phenomenon known as neutrino oscillations. For a long time scientists have suspected that the three known types of neutrinos can morph into each other. Several [...]
TweetWe have shown throughout the Imagineer’s Chronicles there are many theoretical advantages to defining the universe in terms a continuous non-quantized field of energy/mass and four *spatial* dimensions instead of four-dimensional space-time. One is that it would allow one to quantifiably derive the origins of our present universe in terms of a cycle of expansions [...]
In the comments to the previous post, Monty asks a perfectly good question, which can be shortened to: “Is the Higgs boson really necessary?” The answer is a qualified “yes” — we need the Higgs boson, or something like it. That is, we can’t simply take the Standard Model as we know it and extend [...]
