(Phys.org) —Scientists this week heard their first pops in an experiment that searches for signs of dark matter in the form of tiny bubbles. Scientists will need further analysis to discern whether dark matter caused any of the COUPP-60 experiment's first bubbles. http://phys.org/news286708846.html Physics Thu, 02 May 2013 10:20:56 EST news286708846 (Phys.org) —What will soon be the most powerful neutrino detector in the United States has recorded its first three-dimensional images of particles. http://phys.org/news283691479.html Physics Thu, 28 Mar 2013 12:11:26 EST news283691479 Amongst all known elementary particles, the top quark is peculiar: weighing as much as a Tungsten atom, it completes the so-called 3rd generation of quarks and is the only quark whose properties can be directly measured. Owing to its mass, the top quark is unstable and, in CMS, decays much before it can interact with the proton remnants through the strong interaction and form hadrons (the bound states of quarks). It decays mostly to a W boson and a bottom (b) quark, and can therefore be identified from final states which involve the complete usage of the CMS detector; electrons, muons, jets, missing transverse energy—almost all particles or experimental signatures one can think of may be produced in top-quark events. http://phys.org/news271323678.html Physics Mon, 05 Nov 2012 07:41:34 EST news271323678 Magnet size is crucial to an accelerator as it determines the final circumference and power. This spring, Fermilab unveiled a 10.4 Tesla magnet that is shorter than the 8 Tesla magnets currently installed in the LHC. These new magnets will be a valuable asset to the HL-LHC, the next step of the LHC machine. http://phys.org/news265445030.html Physics Wed, 29 Aug 2012 07:44:06 EST news265445030 (Phys.org) -- After more than 10 years of gathering and analyzing data produced by the U.S. Department of Energy's Tevatron collider, scientists from the CDF and DZero collaborations have found their strongest indication to date for the long-sought Higgs particle. Squeezing the last bit of information out of 500 trillion collisions produced by the Tevatron for each experiment since March 2001, the final analysis of the data does not settle the question of whether the Higgs particle exists, but gets closer to an answer. The Tevatron scientists unveiled their latest results on July 2, two days before the highly anticipated announcement of the latest Higgs-search results from the Large Hadron Collider in Europe. http://phys.org/news260444993.html Physics Mon, 02 Jul 2012 10:50:15 EST news260444993 More clues are expected next week in the worldwide hunt for an elusive sub-atomic particle, the Higgs boson, that is the missing piece in the standard model of physics. http://phys.org/news260341480.html Physics Sun, 01 Jul 2012 06:05:16 EST news260341480 (PhysOrg.com) -- Physicists working at Fermilab, the premier particle physics lab in the United States, have been asked to rework their plans for the Long-Baseline Neutrino Experiment (LBNE) in light of current and expected budget cuts. The request came from William Brinkman, director of the Department of Energy’s Office of Science, which was to provide over a billion dollars in funding for the experiment over the next several years. The director cited proposed cuts to the DOE’s budget by the White House and suggested that such cuts are likely to occur for the foreseeable future. Fermilab director Pier Oddone has responded by posting comments to the LBNE page insisting that the lab will remain committed to achieving its original goals but will need to find another way to reach them. http://phys.org/news252050275.html Physics Tue, 27 Mar 2012 06:58:13 EST news252050275 In this month's Physics World, reviews and careers editor, Margaret Harris, visits the Fermi National Accelerator Laboratory (Fermilab) to explore what future projects are in the pipeline now that the Tevatron particle accelerator has closed for good. http://phys.org/news247248489.html Physics Tue, 31 Jan 2012 19:00:10 EST news247248489 (AP) -- Aside from the slogan on the water tower that reads "City of Energy," there is little in this leafy Chicago suburb of gently rolling hills to indicate that it has been the center of the universe when it comes to studying, well - the universe. http://phys.org/news236448465.html Physics Wed, 28 Sep 2011 17:07:56 EST news236448465 (AP) -- Betting against Einstein and his theory of relativity is a way to go broke. For more than a century, everyone from physicists to the Nazi Party - which encouraged the publication of the tract "One Hundred Authors Against Einstein" - has tried to find cracks in his work. And all have failed. http://phys.org/news236021957.html Physics Fri, 23 Sep 2011 18:43:00 EST news236021957 The elusive Higgs Boson, known as the "God particle", is -- if it exists -- running out of places to hide, the head of the mammoth experiment designed to find it said on Thursday. http://phys.org/news233481121.html Physics Thu, 25 Aug 2011 08:52:22 EST news233481121 Scientists of the MINOS experiment at the Department of Energy's Fermi National Accelerator Laboratory announced today (June 24) 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. http://phys.org/news228155249.html Physics Fri, 24 Jun 2011 17:28:55 EST news228155249 (PhysOrg.com) -- In April, scientists at one of Fermilab’s two particle detectors, CDF, observed what they thought might be a new particle not predicted by the Standard Model. But now, scientists at the lab’s second detector, DZero, have cross-checked the observation with their own independent data and analysis tools, and have found no evidence of a new particle. Instead, the DZero data are in agreement with predictions from the Standard Model. http://phys.org/news227199883.html Physics Mon, 13 Jun 2011 16:05:41 EST news227199883 (PhysOrg.com) -- Over the weekend, at a physics conference in France, Fermilab CDF collaboration member, Giovanni Punzi, gave a presentation where he showed some slides that appeared to back up the rumors that cropped up a month ago on the Internet, suggesting the team had found some evidence that might hint at the existence of a previously unknown particle; which would of course refer to the infamous Higgs Boson. http://phys.org/news226139348.html Physics Wed, 01 Jun 2011 09:30:34 EST news226139348 Data from a major US atom smasher lab may have revealed a new elementary particle, or potentially a new force of nature that could expand our knowledge of the properties of matter, physicists say. http://phys.org/news221304873.html Physics Wed, 06 Apr 2011 13:15:26 EST news221304873 (PhysOrg.com) -- In a recent paper posted at arXiv.org and submitted to Astrophysical Journal, Dan Hooper and Jason Steffen, physicists at Fermilab in Illinois, present the theory that cold and dark planets, not heated by a star, could be heated by dark matter. In theory, this dark matter could produce habitable planets outside of what is known as a habitable zone. http://phys.org/news220881011.html Physics Fri, 01 Apr 2011 12:51:04 EST news220881011 (PhysOrg.com) -- The 25-year-old Tevatron particle accelerator in the US will end its operations in September this year since no funds are available to extend its life for three more years. http://phys.org/news213951288.html Physics Tue, 11 Jan 2011 08:00:12 EST news213951288 (PhysOrg.com) -- If looking for the elusive Higgs boson particle is like searching for a needle in a haystack, research published last month has made the haystack smaller. http://phys.org/news201444350.html Physics Thu, 19 Aug 2010 13:46:27 EST news201444350 (PhysOrg.com) -- A rumor that Fermilab’s Tevatron may have discovered evidence of a light Higgs boson wouldn't be the first unsupported speculation from Tommaso Dorigo, a physicist at the University of Padua in Italy, on his lively blog, but it is probably one of the most intriguing. Even a slight possibility that the world’s second largest accelerator has beaten the largest, the Large Hadron Collider (LHC), in finding the last particle in the Standard Model is enough to catch most people’s attention. http://phys.org/news198202639.html Physics Tue, 13 Jul 2010 06:28:30 EST news198202639 (PhysOrg.com) -- Two separate collaborations involving Indiana University scientists have reported new results suggesting unexpected differences between neutrinos and their antiparticle brethren.
