The most precise single measurement of the top quark has revealed a mass with a precision of better than one percent. A total of 630 selected top quark pairs in 4.3 inverse femtobarns of collected data yield the final result for the top mass: m_top = 172.64 +- 1.58 GeV/c2.

The US Department of Energy has provided Fermilab with $9 million in funds from the American Recovery and Reinvestment Act for a long-baseline neutrino project. The laboratory is currently spending the funds on preliminary design.
"This is an opportunity to send money into the technical community outside the laboratory," said Regina Rameika, a Fermilab scientist who is coordinating the design efforts.

These blog started because I produced my own theory of what the dark energy fluid is composed of , which required adding a new force to physics . Could the all ready know forces of physics create dark energy . Up to now , everyone thought the answer was no , dark energy was from something extra not in the Standard Model . Then last week Federico Urban and Ariel Zhitnitsky published a paper The QCD Nature of Dark Energy It does something miraculous , it explains dark energy using one of the know existing forces , namely the strong nuclear aka Color . force QCD or

The global demand for electricity is likely to double by 2030. But could particle accelerator technology help solve the world energy crisis? According to scientists, accelerators might make it possible to use an alternative fuel to produce nuclear energy.

On Monday, October 26, the U.S. Department of Energy's Office of Science will host a Symposium on Accelerators for America's Future in Washington, DC. The symposium--drawing participants from science, industry, medicine, and the national security community--will focus on challenges and opportunities in maximizing the potential of next-generation accelerator technologies to energize the U.S. economy, strengthen American competitiveness, and help the nation achieve more in science, industry, medicine, energy and the environment, and national security.

This has been the known state of the act of physics since the late forties . Is it still possible there are more unknown forces at work in the universe . Certainly cosmologist have found known matter to be just 5 of the universe , and dark matter and dark energy could easy interact with unknown forces of which we could say little . Here however I want to see whether current measurement allow for any extra force acting on the sort of matter we find on earth , i.e . acting on neutrons , protons or . electrons Since I've been making a claim of a new force in my paper and on this blog , axitronics it behoves to me the duty , of every so often checking physics papers to see if any new experiments rule out my force .

I’m releasing two papers that relate Heisenberg’s uncertainty principle, spin-1/2, the generations of elementary fermions, their masses and mixing matrices, and their weak quantum numbers. I haven’t blogged anything about these because I’ve been so busy writing, but I should give a quick introduction to them.
Heisenberg’s uncertainty principle states that certain pairs of physical observables [...]
