New 'Mystery Meson' Sub-Atomic Particle Discovered

securitas writes "The BBC reports that scientists in Japan have discovered a new sub-atomic particle that defies current theories of matter and energy. The 'mystery meson' X(3872) was revealed while studying beauty quarks at the KEK High Energy Accelerator Research Organization Tsukuba meson factory. 'It weighs about the same as a single atom of helium and exists for only about one billionth of a trillionth of a second before it decays into other longer-lived, more familiar particles.' Scientists say the lifespan 'is nearly an eternity for a sub-atomic particle this heavy' and may require a change in current theory. Possible explanations for this include the particle being comprised of two quarks and two antiquarks, instead of the usual one-one pairing. More explanation and illustrations at KEK."

I always loved particle physics

gotta love how they study something by smashing it into peices. I always pictured using the same technique to study how a radio works by shooting bullets into it, and then observing the peices as they fly out of the radio :-)

How do we know that you didn't have a purple dragon in your garage for about one billionth of a trillionth of a second?

A college Philosophy professor of mine tells a story about high energy physics and the practitioners thereof. He was researching a book on the philosophy of science and was interviewing one of the researchers at Fermilab (I think).

After discussing some of the esoterica of the field, my professor says "Okay. Off the record, do you *actually* believe that some of these particles exist outside of mathematical equations?"

Scientist looks around and replies "Not really. But this stuff is a lot of fun!"
