Physicists Discover New Particle!

July 21, 2011 Leave a comment

Researchers at the soon-to-be-closed-but-won’t-go-quietly Fermilab, have confirmed the existence of the neutral Xi-sub-b baryon.

Baryons are particles composed of three quarks; quarks being elementary of particles. Other baryons include protons and neutrons. The newly discovered Xi-sub-b baryon is about six times more massive than the proton.

The Fermilab press release states:

Combing through almost 500 trillion proton-antiproton collisions produced by Fermilab’s Tevatron particle collider, the CDF collaboration isolated 25 examples in which the particles emerging from a collision revealed the distinctive signature of the neutral Xi-sub-b. The analysis established the discovery at a level of 7 sigma. Scientists consider 5 sigma the threshold for discoveries.

Wow, 7-sigma! That’s a pretty high level of certainty.

Unfortunately, due to a lack of funding, the Tevatron particle accelerator at Fermilab will close operations in October of 2011. Way to go out with a bang guys!

Yesterday was Nikola Tesla’s birthday, the man who is most famously known for giving us alternating current (AC).

In celebration, enjoy ‘Poker Face’ by Lady Gaga played with Tesla Coils!

And it’s being taught in schools. I know its an issue that has been around for awhile (and isn’t going away), but I think it’s good to remind people this is happening.

Some cool stuff happening in and around space these last couple days.

This video from the Solar Dynamics Observatory shows a comet streaking across the face of the Sun!!

And of course, the final shuttle launch EVER happened earlier today.
