# Photon spin ?

1. ### cragar

My teacher said in class a while back that a photon can have a spin of -1 , 0 , 1 ,
Is this correct , And also it says on Wikipedia that photons and gluons and W and Z bosons can have 3 different possibilities for their spin angular momentum , obviously Wikipedia could be wrong
http://en.wikipedia.org/wiki/Stern–Gerlach_experiment
if you look in the Basic theory and description section on the wiki article about 80% the way down it had photons and W and Z bosons highlighted in blue and talks about their spin ,
I have not studied QM very much ,
