Hadrons may be either a baryon or a meson
Anti-hadrons may be either an anti-baryon or an anti-meson
The baryon Δ++ was discovered in a particle accelerator using accelerated positive pions on hydrogen targets.Which of the following is the quark combination of this particle?
The baryon number of a particle depends if it is a baryon, anti–baryon or neither
Show that the baryon number is conserved in β– decay.
Pions consist of up and down quarks, and their respective antiparticles, depending on their sign
Kaons consist of up, down and strange quarks, and their respective antiparticles, depending on their sign
