During the last two weeks of December have seen quite hearsay and excitement regarding the possible detection of weakly interacting particles, better known as WIMPs its acronym in English. As we all know, the WIMPs are some potential candidates to be the Universe's dark matter, that matter seems to gravitate to exercise force, but is more or less than invisible. So far, by its very nature, were not detected.
In fact, I still can not say that have been identified, despite the desire to do so by certain communities within the current Physics. It was so much that even became an Internet broadcast of a talk in which they presented the results before they were even published in the arXiv repository. Apparently there was a computer problem pdf file sent to the system and the automatic release mechanism did not work. Fortunately there are already available copies of the original article posted on the Internet.
CERN Director congratulates the physicists and engineers for the successful implementation of the great scientific machine
At 1810 hours on Wednesday over the full phase the first operations of the new particle accelerator LHC, as reported by Rolf Heuer, director of the European Laboratory for Particle Physics (CERN), near Geneva, to all staff the same. "The crash made to 2.36 TeV (tera) since last weekend set a new world record and closes the first stage of operation," he says. From now on, the LHC will stand up to restart its operation in February next year.
In these coming weeks will be carried out technical work needed to increase the power of the accelerator and get started the real scientific research program. You can repair minor damage found in the commissioning phase that began in late October, including those that affect the cooling system of the CMS detector.
CERN Control Centre, which this weekend witnessed the restart of the LHC, more than a year after the initial launch on 10 September 2008. The atmosphere was electric as all eyes were trained on the monitors showing protons circulating in opposite directions at the injection energy of 450 giga-electronvolts. Today, I'm delighted to welcome Steve Myers, Director for Accelerators and Technology, who's here to tell us all about the restart of the LHC. But first let's enjoy some of the images that marked this historic day for the Organization.
Standard Model of particle physics The standard model of physics particles is a theory that describes the relationships between the known fundamental interactions between elementary particles that make up all matter. It is a quantum field theory developed between 1970 and 1973 that is consistent with quantum mechanics and special relativity. To date, almost all experimental tests of the three forces described by the standard model agrees with their predictions. However, the standard model fails to be a complete theory of fundamental interactions because it does not include gravity, the fourth known fundamental interaction, and because of the large number of numerical parameters (such as masses and coupling constants) to be put in hand in the theory (rather than derived from first principles.) Today in physics, the dynamics of matter and energy in nature is best understood in terms of kinematics and interactions of fundamental particles. To date, science has succeeded in reducing the laws seem to govern the behavior and the interaction of all types of matter and energy we know, a small set of laws and theories. A major goal of physics is to find the common ground that would unite all these in a theory of everything, in which all other laws that we know would be special cases, and which may result from the behavior of all matter and energy ( ideally from first principles.) Within this, the standard model includes two major theories - the electroweak model and quantum chromodynamics - which provides an internally consistent theory that describes the interactions between all particles observed experimentally. Technically, quantum field theory provides the mathematical framework for the standard model. The standard model describes each type of particle in terms of a mathematical field. For a technical description of the fields and their interactions, see Standard model (basic details).
For ease of description, the standard model can be divided into three parts which are matter particles, the particles that mediate forces, and the Higgs boson.
On November, 2007 the most complex scientific instrument ever built will be switched on. The Large Hadron Collider promises to recreate the conditions in the early universe. By revisiting the beginning of time, scientists hope to unravel some of the deepest secrets of our Universe. Within these first few moments the building blocks of the Universe were formed. The search for these fundamental particles has occupied scientists for decades but there remains one particle that has stubbornly refused to appear in any experiment. The Higgs Boson is so crucial to our understanding of the Universe that it has been dubbed the God particle. It explains how fundamental particles acquire mass, or as one scientist plainly states: "It is what makes stuff stuff..."
A video by Cern with Peter Higgs talking about his lifes work, the Higgs mechanism and the hunt for the mass-conferring particle named after him, the Higgs boson, video date 01 July 2004. A brief summary of fermions, bosons and supersymmetry Partículas de materia Según el modelo estándar toda la materia known is made up of particles having an intrinsic property called spin whose value is 1 / 2. In terms of the standard model all particles of matter are fermions. For this reason, follow the Pauli exclusion principle according to statistics theorem of spin, and is what causes the material quality. Apart from their anti-partners, the standard model explains a total of twelve different types of particulate matter. Six of these are classified as quarks (up, down, strange, charm, top and bottom), and the other six as leptons (electron, muon, tau, and their corresponding neutrinos).

nostalgic for all that we've grown up seeing the pictures of loving bears (bears caring for Latin America) have translated into a pattern that I found on net. Soon I will leave employers with different symbols of their tummies.
