Here's a question
I've been thinking, but I'm probably wrong..
A neutral pion can have either up-antiup quark pair or down-antidown pair.
A proton-antiproton pair has in total 2 ups, one down, two antiups, and one antidown all together which is a perfect match for making equal amounts of...
Here it is, but the table is on the end somewhere:

About the theoretical predictions of branching, It's interesting you brought that up, because I also found a publication comparing calculations with practical observations from Cern, in fact...
Well they do have antiproton decelerator at CERN and other methods of cooling down anti-protons, so if not total rest, they certainly can get the energy down to change results
In the meantime , I finally found the branching ratios for p anti-p
here is one table, this is from a PDF presentation...
Well, this is all pretty new for me, so I'm not sure if that's what it's called
but what I'm looking for would be branching ratios of various outcomes of annihilation at rest. Between protons-antiprotons, electron-positrons and neutron-antineutrons.
Now, are there similar charts in existence for annihilation events between various particles and antiparticles at low energies ("static")? In other words, should I even look for such a thing?
Hi, thanks for answers, the site you mentioned indeed contains exactly what I've been looking for.

Hello
I'm looking for a list,as complete as possible, of decay modes and their probabilities, for all known subatomic particles.
I've been googling, but found only bits and pieces. Perhaps someone knows a place on internet, or has found a free document to share, or anything like that
thanks
But just so this thread doesn't go to waste, I'm going to ask, this this equation still hold if your "exhaust" is in form of radiation?
In other words, can a self-fueled laser be a classical rocket.
I know radiation has momentum, but I'm just wondering if there is a catch
Now this is embarrassing
I did actually read the whole page, and entered everything into matlab, to get some nice curves out, and then started getting strange results, actually I was getting out complex numbers, lol, so I thought maybe I didn't understand the equation right, which is why I...
Hello there
I've been looking at this page
http://en.wikipedia.org/wiki/Relativistic_rocket
at the relativistic version of Tsiolkovsky rocket equation, but something puzzles me
With chemical rockets, the mass that is being converted into energy is so tiny that almost
all fuel...
