Strange but charming new particle found

How bizarre!!

Just goes to show, we know as much about the micro universe as we do about the macro universe. The smaller you go, the weirder it gets!

Scientists working on Fermilab's SELEX experiment have found a odd new sub-atomic particle in the 'heavy-light' meson family. The researchers are intrigued because the meson lives longer than it should, weighs more than it should, and decays into unexpected particles.

Typically, the heavier the meson, the faster it decays. However, this meson - a combination of a strange quark and a charm antiquark - is the heaviest meson ever observed in this family, yet it lasts three times as long as its lighter relatives.
