state for each one whether it is possible or impossible, (astroparticle physics)

–+ p p+K

Solution

Baryon number is conserved. left side : 0+1=1 , right side:1+0=1

However charge is not conserved. left side: (-1 + 1) = 0, right side:(1+0)=1.

So, we need not check any other coservation laws. This process is not possible.
