Conservation laws
Charge
sum of charge before should equal sum of charge after
Baryon number
number of baryons before should equal number of baryons after

Four types of interactions
Electromagnetic
between charged particles, kQq/r², exchange photons
Strong
between quarks, r=10^(-15), exchange gluons
Weak
between quarks and leptons, r=10^(-18), exchange W+, W- and Z bosons
Gravitational
between all particles, GMm/r², exchange gravitons
