Surprised this one hasn't been mentioned yet:<br /><blockquote><font class="small">In reply to:</font><hr /><p><b><font color="red">New Form Of Asymmetry Between Behavior Of Matter And Antimatter Discovered</font><br /><br />Finding something expected has brought researchers at the Department of Energy's Stanford Linear Accelerator Center (SLAC) one step closer to discovering the unexpected.</b><br /><br />SLAC's BaBar collaboration has discovered that CP violation -- an asymmetry between the behavior of matter and antimatter -- exists even in a very rare class of particle decays. This result offers the most sensitive avenue yet for exploring matter-antimatter asymmetries, with implications for the future understanding of physics beyond the Standard Model.<br /><br />"BaBar has proven to be a fantastic instrument for exploring the origins of matter-antimatter asymmetries, allowing us to probe with exquisite precision very rare processes related to how the early universe came to be matter dominated," said David MacFarlane, BaBar Spokesperson and Professor at the Stanford Linear Accelerator Center.<br /><br />The Standard Model theory provides a beautifully consistent picture of the building blocks of the subatomic world around us and the forces between them. Yet we now know it only describes 5 percent of the total mass of universe and leaves many fundamental questions in particle physics and cosmology unanswered. The very rare particle decays studied by the BaBar collaboration could offer the first hints of a breakdown of the Standard Model. By reaching the threshold where asymmetries in such decays can be seen, the BaBar collaboration has opened the door to finding new physics.<br /><br />"Demonstrating a significant level of CP violation in these rare modes is a watershed for BaBar," said Professor Fernando Palombo of the INFN (the Italian Nuclear Physics Institute) and the Departm</p></blockquote> <div class="Discussion_UserSignature"> <p style="font:normalnormalnormal12px/normalTimes;margin:0px"><strong>Mere precedent is a dangerous source of authority.</strong></p> <p style="font:normalnormalnormal12px/normalTimes;margin:0px">-Andrew Jackson (1767-1845)</p> </div>

Actually, that topic was discussed a goodly while ago, IIRC here in this thread. But this is a very interesting topic, and re-discussing it is well and good.<br /><br />Thank you for posting it. <div class="Discussion_UserSignature"> <p><em>Differential Diagnosis:  </em>"<strong><em>I am both amused and annoyed that you think I should be less stubborn than you are</em></strong>."<br /> </p> </div>
