Aspects of the forces 25 2020
EM force: Boson is Y-masters, uncharged, does not interact with other photons
-Conservas everything α Ufurate range: F= 2 Em (Coulomb Fore) 2
Weak Core:
chaged ournent (cc)
Neutral wment (NC)
CC: Mediated by W booons, anly force Lopable of changing flavour
Within generation
quires (4) (5) (6) azages generations
NC: Couples partides to ante paakiches

F= fo fermion

Zo does not couple aurora gerarations No flavour changing neutral cuments (FCNE)

Suppress range of fore.
Intrinisically the weak fove is stronger than the EM fore the trong range achounts for ito 'Weakness'
Strong Force:
Boson is the gluan, y
-marolers
-bi coloured
carnes a colour and anticoleur charge

There are 8 ghans of different color contrations
The only the missing is the 'Lolourters' ghon le 9~ would he a choryd gluer-dessut east
This has consequences R°:
with colour+ ars colour
12° lanst deuay line
Single gluon decays like this can't happen
Since gluons one coloured they can interact with
then selues
lele
trilinear
Quantic coupling
The strang force behaves lihe
S F = -k r2
k=1Gev/fm
At large distances, the strong force is constant negardless of sepe ation
