Hi all,
(1) What is the difference between electron & positron?
I know that they have opposite charges, but what does that deeply mean?
Someone told me that the different sign of the charge is related to the spin:
Electron is said to have spin up if it is spinning CCW, but the positron is said to have spin up if it is spinning CW.
Is that right? If so, can someone explain it more?
& If that's true what will be the difference between an electron with spin up & a positron with spin down?
(2) What does different values of spin physically mean? Is it related to the speed of spinning? What is the difference physically between integer spin & half integer spin?
Thanks
