Have you ever read a post on a subject you felt like you knew a little bit about, and subsequently been absolutely certain that you've missed the entire point due to your now apparent ignorance?

"Doc! Doc! What the hell is an inverse femtobarn?"
No, seriously, I'm into this kind of stuff and I've never heard of that.

Femto is like "milli" or "micro", but equal to 10 to the -15th
or 0.000000000000001 A "barn" is a measure of area (10 to the -28 square meters) or about the size of the uranium nucleus (femtobarn = code word from WWII days of developing the atomic bomb) And from my old math books I finally get use that famous phase: It naturally follows that: ![]() The inverse femtobarn is how many particle collision events per femtobarn. Oh, and here is another phase. The derivation is left to the reader. ![]() Oh, oh. Here is something that tickled me... The Higgs particle was named the "God particle" by Peter Higgs, who said, "No one around him would allow it to be called "that God damn particle". .

God particles per femtobarn - how much is that in angels per needle point?

Okay, femto = 10 to the -28. Inverse femto = 10 to the 28. But barn is area and you don't measure data in terms of area. How can you have any amount of barns of data? Shopkeeper, I'll have five cubic hours of oranges, please. I suspect leg-pulling. Maybe a mishievous scientist is feeding BS to an incredulous journalist.

I think the way to look at it is... as the collider runs over time,
the accumulated area of the particles increases. This value needs to be corrected for the inefficiency of each specific collider in detecting 100% of the particles (fudge factor=luminosity) I don't really know what I just said... ![]() maybe someone can offer a better explanation. But, in the meantime, as quoted directly from Wikipedia Quote:
they will also need a much bigger computer. ![]() . |
