I was listening to the news yesterday morning, and I heard a short mention that the gang down at the LHC had discovered a new particle, the Chi_b (3P) particle, as they call it, which is composed of a bottom - antibottom pair. It's is supposedly involved in the Nuclear Force, somehow, and I have always had an extremely deep interest in particle physics and fundamental forces, so I'd be excited to know how this particle is involved. If anyone knows anything about it, or has any links to experimental documents, I'd be very interest, and I'm sure the rest of the forum would be too.
