Which of the following strong reactions (from a collision) is possible?
a. p + p --> p + n + K+
b. p + p --> Λ0 + K0 + p + π+
c. p + p --> p + p + π+ + π-
d. p + p --> p + n + π+
Conservation of the Baryon Number (http://hyperphysics.phy-astr.gsu.edu/hbase/Particles/Parint.html#c2)
The Attempt at a Solution
(replaced the original symbols with what I think is the correct baryon number for each particle?)
a. 1 + 1 --> 1 + 1 + 0 (Possible)
b. 1 + 1 --> 0 + 0 +1 + 0 (Not possible)
c. 1 + 1 --> 1 + 1 + 0 + 0 (possible)
d. 1 + 1 --> 1 + 1 + 0 (Possible)
My solution: A, C, and D are possible.
I'm confused with identifying the baryon numbers, I'm pretty sure I'm doing it incorrectly. I'm also confused when a particle has a negative baryon particle vs a positive one, and I'm also confused on how to identify baryons vs masons. I'm only taking AP Physics in high school, none of this stuff is in my textbook (which isn't even an AP textbook in the first place), and my teacher decided to make up this curriculum on her own :/
I should also mention that I got this problem from a list of practice problems that the teacher gave us for our modern physics test tomorrow. You'll definitely be seeing the bubble chamber soon on here as well :/
