http://phys.org/ en-us Phys.org internet news portal provides the latest news on science including: Physics, Nanotechnology, Life Sciences, Space Science, Earth Science, Environment, Health and Medicine. In the vast particle landscape, there are, to borrow a phrase, known knowns (the Standard Model, for example), unknown unknowns (exotic extensions of the Standard Model and beyond), and those ever-interesting known unknowns. A recent CMS observation perfectly fits into this third category. When looking at proton collisions where a J/ψ and a φ meson are produced, CMS observed two unexplained peaks in the data. The first of these structures is consistent with a similar observation made by the CDF collaboration at the Tevatron in 2009, known as Y(4140). http://phys.org/news275209707.html Physics Thu, 20 Dec 2012 07:08:39 EST news275209707 Scientists working on the CMS experiment at the Large Hadron Collider have confirmed the existence of an odd, puzzling particle first observed a few years ago at DOE's Tevatron particle collider. Members of the CMS collaboration announced on Nov. 14 that they had spotted the curious object, dubbed Y(4140), which scientists had discovered at the CDF experiment at Fermilab. http://phys.org/news273834479.html Physics Tue, 04 Dec 2012 09:08:08 EST news273834479 (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 (PhysOrg.com) -- New measurements announced today by scientists from the CDF and DZero collaborations at the Department of Energy’s Fermi National Accelerator Laboratory indicate that the elusive Higgs boson may nearly be cornered. After analyzing the full data set from the Tevatron accelerator, which completed its last run in September 2011, the two independent experiments see hints of a Higgs boson. http://phys.org/news250276968.html Physics Wed, 07 Mar 2012 04:00:01 EST news250276968 (PhysOrg.com) -- Just as firemen use different methods to narrow the location of a person trapped in a building, scientists employ two techniques to find the hiding place of the theorized Higgs particle: direct searches for Higgs interactions and precision measurements of other particles and forces. http://phys.org/news249240191.html Physics Thu, 23 Feb 2012 17:23:30 EST news249240191 (PhysOrg.com) -- An incredibly rare sub-atomic particle decay might not be quite as rare as previously predicted, say Cornell researchers. This discovery, culled from a vast data set at the Collider Detector at Fermilab (CDF), is a clue for physicists trying to catch glimpses of how the universe began. http://phys.org/news233289846.html Physics Tue, 23 Aug 2011 03:45:09 EST news233289846 (PhysOrg.com) -- Scientists of the CDF collaboration at the Department of Energy's Fermi National Accelerator Laboratory announced the observation of a new particle, the neutral Xi-sub-b (Ξb0). This particle contains three quarks: a strange quark, an up quark and a bottom quark (s-u-b). While its existence was predicted by the Standard Model, the observation of the neutral Xi-sub-b is significant because it strengthens our understanding of how quarks form matter. Fermilab physicist Pat Lukens, a member of the CDF collaboration, presented the discovery at Fermilab on Wednesday, July 20. http://phys.org/news230394962.html Physics Wed, 20 Jul 2011 15:36:27 EST news230394962 (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) -- Scientists of the CDF experiment at the Department of Energy's Fermi National Accelerator Laboratory announced yesterday that they have found evidence of an unexpected particle whose curious characteristics may reveal new ways that quarks can combine to form matter. The CDF physicists have called the particle Y(4140), reflecting its measured mass of 4140 Mega-electron volts. Physicists did not predict its existence because Y(4140) appears to flout nature's known rules for fitting quarks and antiquarks together. http://phys.org/news156595642.html Physics Wed, 18 Mar 2009 11:48:17 EST news156595642
