Physics world buzzing over faster-than-ever particles
Physics world buzzing over faster-than-ever particles
Strong evidence found of particle that switches between matter and anti-matter

A major physics lab in the U.S. has found a particle, far smaller than any atom, that switches itself back and forth between being a piece of matter and a piece of anti-matter 17 trillion times each second.

It has taken 700 people in 20 countries, millions of dollars' worth of custom equipment, vast amounts of energy, and 20 years of work to find this.

The back-and-forth switching appears to be one of the fastest processes in nature.

1. 17 trillion times a second?
How in the world did they measure THAT? It sounds like the source of pure energy or something.

Still not quite as high as the national debt, though, is it?

2. Wow, that's faster than Oprah's thin/fat cycling!
Seriously, though, that's pretty damned amazing.

3. Let's think about what this means
is something not being conserved here?

charge? spin?

27. That Was My Question
although matter-antimatter parity is one thing that's obviously NOT conserved. It still seems odd.

5. The more you take things apart, the weirder they get
on the subatomic levels.

They've pretty much figured out that "matter" is just loops of energy with different spin and different properties.

6. Here is the official Fermilab press release
if you want the news straight from the source.

BTW, Fermilab is a public access DOE lab outside of Chicago (Batavia, IL) and is worth visiting if you are ever in the area.

7. I got a tour of SLAC when I was a kid
That's the Stanford Linear Accelerator Center at Stanford University in California. My grandfather was one of the engineers who helped to design the cooling system.

10. Truly fascinating. However, I hate to see the word trillion used.
It only encourages the current administration to raise the debt ceiling to that number.

Also, I wonder if people in Kansas will be allowed to read about this.

14. Acording to the fermilab link provided above
A meson, such as the B_s, is an unusual particle made up of both matter and antimatter-one quark and one antiquark. The neutral B_s meson is composed of a bottom (or "B") antiquark and a strange ("s") quark.

20. Yeah, I read it, that's sort of a joke question.
It's not made of much of anything, unless you count "energy", and we don't really know what energy is made of either, it's fundamental. All we REALLY know is these things seem to obey certain equations when we experiment with them.

24. Dop You Have Any Insight into Why the Oscillation Happens?
I never heard of a combination of a quark and and anti-quark, much less that it changes between states. I would be fascinated to know why this combination is able to express itself both as matter and anti-matter, and how the researchers can tell (maybe it's the result of how it's measured).

26. Quark - antiquark pairs are common
The so-called "flavorless" mesons are made from a quark - antiquark pair of the same type (*). "Flavored" mesons have two different quarks. I will try to find some info, but I don't think the quarks in flavored mesons both must be matter or anti-matter, and that the observed state-change in this and other mesons is the result of a quark-antiquark pair of different types.

(*)I probably have the nomenclature wrong, but there are six types of quarks, grouped in three sets of two. They are up/down, strange/charm, and top/bottom. Quarks make a class of particles called fermions, which include protons and neutrons. Most of the fermions in the universe seem to made up of up/down quarks, although more exotic fermions have been made.

13. What percentage of the speed of light does this particle travel
Edited on Wed Mar-29-06 02:22 PM by puerco-bellies
If the mass of an object approaching the speed of light increases is this particle affected? As I recall objects increase in mass to near infinite as they get closer to light speed. I think that this effect was one of the barriers to at or near light speed travel. If this particle is close to "light speed" is it affected? If not, why? Is it a repudiation of a part of the theory of relativity? Could this be a key to near light speed travel? Has it been to long since my last physics class?

Edited for spelling.

17. I don't think light speed is relevant
If a particle is merely changing state, like this one, the delta of positional change (ie speed as you are using it) is not a factor.

23. So, this thing just spontaneously flips between matter and antimatter?
That's pretty weird, isn't it? I didn't notice anybody in that article saying "this is pretty weird." Am I missing something?

25. Actually, it isn't all that weird
There are other particles that flip-flop (and not all of them are politicians.) Where this one is unusual is that it occurs much faster than any other we know about. Noteable, but not weird.

I dare say that the more you've studied quantum physics, the more likely you are to just nod your head and say, "Cool!" when stuff like this is discovered.
