Topic: Atom Smashers Get an Antimatter Surprise | |
---|---|
The world's largest atom smasher, designed as a portal to a new view of physics, has produced its first peek at the unexpected: bits of matter that don't mirror the behavior of their antimatter counterparts.
The discovery, if confirmed, could rewrite the known laws of particle physics and help explain why our universe is made mostly of matter and not antimatter. Scientists at the Large Hadron Collider, the 17-mile (27 km) circular particle accelerator underground near Geneva, Switzerland, have been colliding protons at high speeds to create explosions of energy. From this energy many subatomic particles are produced. Now researchers at the accelerator's LHCb experiment are reporting that some matter particles produced inside the machine appear to be behaving differently from their antimatter counterparts, which might provide a partial explanation to the mystery of antimatter. [The Coolest Little Particles in Nature] Scientists think the universe started off with roughly equal amounts of matter and antimatter. (Particles of antimatter have the same mass of their twins but an opposite charge.) Somehow over the ensuing 14 billion years, most of the antimatter was destroyed, leaving a leftover universe of mainly matter. One potential explanation for this outcome is called "charge-parity violation." CP violation means that particles of opposite charge behave differently from one another. The LHCb researchers found preliminary evidence that this is happening when particles called D-mesons, which contain "charmed quarks," decay into other particles. The whimsically named charmed quarks, like many exotic particles, are so unstable, they last only a fraction of a second. They quickly decay into other particles, and it is these products that the experiment detects. ("LHCb" is short for LHC-beauty, another flavor of quark.) From the experiment, the researchers found a 0.8 percent difference in the probabilities that the matter and antimatter versions of these particles would decay into a particular end state. Ruling out a fluke When it comes to particle physics, it's all about the quality of statistics. Measuring something once is meaningless because of the high degree of uncertainty involved in such exotic, small systems. Scientists rely on taking measurements over and over again — enough times to dismiss the chance of a fluke. The new finding ranks as a "3.5 sigma" result, meaning the statistics are solid enough that there is only a 0.05 percent likelihood that the pattern they see isn't really there. For something to count as a true discovery in particle physics, it must reach a 5 sigma level of confidence. "It's certainly exciting, and certainly worth pursuing," LHCb researcher Matthew Charles of England's Oxford University told LiveScience. "At this point it's a tantalizing hint. It's evidence of something interesting going on, but we're keeping the champagne on ice, let's say." By the end of 2012, Charles said, the Large Hadron Collider should have collected enough data to either confirm or reject the result. LHC's birthright If the finding is borne out, it would be a big deal, because it would mean the reigning theory of particle physics, called the Standard Model, is incomplete. Currently the Standard Model does allow for some minor CP violation, but not at the level of 0.8 percent. To explain these results, scientists would have to alter their theory or add some new physics to the existing picture. In either case, the LHC would have begun to claim its birthright. "The whole driving purpose of the LHC is to discover and understand new physics beyond the Standard Model," Charles said. "This sort of analysis is exactly why I joined LHCb." One possible example of the kind of new physics that might explain such CP violation is called supersymmetry. This theory suggests that in addition to all the known particles, there are supersymmetric partner particles that differ by half a unit of spin. Spin is one of the fundamental characteristics of elementary particles. So far, no one has found direct evidence of supersymmetry. But if supersymmetric particles exist, they might be created instantaneously and disappear again during the particle-decay process. That way they could interfere with the decay process, potentially explaining why matter and antimatter decay differently. Charles reported the LHCb team's findings this week in Paris at the Hadron Collider Physics Symposium. from LiveScience.com.com |

Wow.
Great explanation. I hope you follow up in 2012. So, when the probability statistics improve, scientists will create a new physics law to cover it? |

the mystery of antimatter :
"God made something from nothing " "FAITH is the SUBSTANCE of things HOPED for and the EVIDENCE of THINGS NOT SEEN " " CALL those THINGS that BE NOT as if they WERE" What science is finding out, is already found in the bible. Science and the bible agree. |

Science and the bible agree. Don't think it's that simple. In Science one needs to be much more precise than that! Besides,Antimatter is not "Nothing". |

Maybe nothing means something entirely different
from what we think nothing means afterall.... check out the link I shared on the other thread on here...read all the other links on there too.... there are also some great books to read ....check them out too..find out what is really happening out there, instead of wasting time just chatting about it... |

Using a book full of metaphore to try to explain science is like trying to explain science based off of the star trek.
Your so far off topic here Morning, I hope a mod deletes these posts. |

Scientists say it so it must be fact huh ?
|
|
|
|
Or any other book dat questioned the status quo i suspect :)
|
|
|
|
Scientists say it so it must be fact huh ? umm... thats why they call it a theory, they are testing it now. some theories pan out, some don't. |
|
|
|
Scientists say it so it must be fact huh ? jeez man. i don't see anybody calling anything fact. the data isn't even expected to be annalysed completely before the end of the year. |

That would be a great name for a television show.....Atom Smashers LOL

Science and the bible agree. God did no such thing. The Abyss existed. God CREATED the rest of it. but he MOVED upon the Abyss. don't ya'll even read your own book? |
