This afternoon, Sept. 30, Fermilab will shut down the Tevatron for the last time. This story honors the operators - the men and women who have kept the accelerators running 24 hours a day, seven days a week, 365 days a year.

Fermilab’s Antiproton Source has long produced the antimatter that makes Fermilab’s particle collisions possible. While the Antiproton Source will shut down along with the Tevatron on Sept. 30, there are plans for its future.
On the eve of the shutdown of Fermilab's Tevatron, collaborators from the CDF and DZero experiments are expressing their gratitude for all the hard work and dedication that made 26 years of capturing billions of proton and antiproton collisions possible. In these final hours of operations, both collaborations are making the pen mightier than the proton by writing notes of thanks and appreciation. 
The TOTEM experiment at the LHC has just confirmed that, at high energy, protons behave as if they were becoming larger. In more technical terms, their total cross-section – a parameter linked to the proton-proton interaction probability – increases with energy. This phenomenon, expected from previous measurements performed at much lower energy, has now been [...]
L’expérience TOTEM du LHC vient de confirmer que, à de hautes énergies, les protons se comportent comme s’ils devenaient plus grands. En termes plus techniques, leur section efficace totale (paramètre lié à la probabilité d’interaction proton-proton) augmente avec l’énergie. Ce phénomène, que des mesures réalisées à des énergies beaucoup plus basses laissaient entrevoir, a été [...]
On Friday Sept. 23, students arrived at control rooms for the LHC and its detectors throughout the evening in groups of five to 10. For the second time, members of the four largest experiments at the LHC at CERN were participating in Researchers’ Night, a Europe-wide event in which members of the public from more than 320 cities spend an evening alongside scientists in action.
So this Friday is the shutdown of Fermilab’s Proton/Anti-Proton Collider the Tevatron. After almost 30 years of service and numerous discoveries the collider has run her course and is scheduled to be turned off. Instead of this being a sad event Fermilab is going to let the old girl go out with a bang! A [...]
While at Bari Conference (see here), the news was spreading that OPERA Collaboration, a long baseline experiment using muon neutrino beams launched by CERN by CNGS Project, detected a possible Lorentz violating effect. Initially, it started as a rumor in the comment area at Jester’s blog (see here). Then, Tommaso Dorigo provided a full account [...]
This week I was in Bari as the physics department of that university organized a major event: SM&FT 2011. This is a biennial conference having the aims to discuss recent achievements in fields as statistical mechanics and quantum field theory that have a lot of commonalities. The organizers are well-known physicists and so it was [...]

The OPERA neutrino experiment announced today the kind of result that keeps a physicist up at night. Scientists revealed that they have observed subatomic particles seeming to travel faster than the speed of light. Leaders of the collaboration will share OPERA data with the world today at 9 a.m. CDT during a seminar to be [...]

Neng Xu, a software engineer for the University of Wisconsin-Madison working on the ATLAS experiment, sat drinking coffee in a sunny corner of CERN’s cafeteria when he thought of a challenge. Could he create a virtual version of what he saw out the window: a lawn with cafe tables and a building across the street?
TweetTime holds a unique place in science and the human consciousness. Some say it is only an invention of the human mind that gives us a sense of order, a before and after so to speak while many physicists define it in terms of the physical properties of a space-time dimension. Both of these definitions [...]
It is some time I am not writing posts but the good reason is that I was in Leipzig to IRS 2011 Conference, a very interesting event in a beautiful city. It was inspiring to be in the city where Bach spent a great part of his life. Back to home, I checked as usual [...]
Forty-one percent of the children in Sudan are malnourished and underweight, according to the Food and Agriculture Organization of the United Nations. Mohamed Eisa, a physicist at the Sudan University of Science & Technology, would like to change this statistic, and he believes that particle accelerators can help.
The strand model, though my favorite, lacks a good explanation for particle masses. It does explain certain mass ratios, but it does not explain the absolute mass values. We should help on this topic.
