Potential Cracks In The Standard Model Of Particle Physics

Recently analyzed data from the BaBar experiment may suggest possible flaws in the Standard Model of particle physics, the reigning description of how the universe works on subatomic scales. The data from BaBar, a high-energy physics experiment based at the U.S. Department of Energy´s (DOE) SLAC National Accelerator Laboratory, show that a particular type of particle decay called “B to D-star-tau-nu” happens more often than the Standard Model says it should. In this type...

Physicists at the U.S.-based Fermilab have produced a new particle that is a heavier relative of the neutron. The Batavia, Illinois atom smasher found the neutral Xi-sub-b by smashing particles together around a 4-mile ring at near light speed.  Physicists knew the particle existed, but it is the first time researchers have observed it firsthand.  Measuring the properties of particles like the neutral Xi-sub-b allows physicists to understand how quarks interact to form matter....

The long, slow decay of carbon-14 allows archaeologists to accurately date the relics of history back to 60,000 years. And while the carbon dating technique is well known and understood (the ratio of carbon-14 to other carbon isotopes is measured to determine the age of objects containing the remnants of any living thing), the reason for carbon-14's slow decay has not been understood. Why, exactly, does carbon-14 have a half-life of nearly 6,000 years while other light atomic nuclei have...

MADISON - When the world's most powerful particle accelerator starts up later this year, exotic new particles may offer a glimpse of the existence and shapes of extra dimensions. Researchers from the University of Wisconsin-Madison and the University of California-Berkeley say that the telltale signatures left by a new class of particles could distinguish between possible shapes of the extra spatial dimensions predicted by string theory. String theory, which describes the fundamental...


Word of the Day
sough
  • A murmuring sound; a rushing or whistling sound, like that of the wind; a deep sigh.
  • A gentle breeze; a waft; a breath.
  • Any rumor that engages general attention.
