Physics/Positron vs. Left-Handed Electron


Can you explain the difference between a positron and a left handed electron?

Hello Frank,

Both electrons and positrons may have either right or left handedness.

I have found 2 differences between a positron and a left handed electron:

1. Both left and right handed electrons have negative charge. Positrons (either right or left handed) have positive charge.
2. Electrons emitted in beta decay are mostly left handed while positrons emitted in beta decay are mostly right handed.

I hope this helps,

I would be delighted to help with questions up through the first year of college Physics. Particularly Electricity, Electronics and Newtonian Mechanics (motion, acceleration etc.). I decline questions on relativity and Atomic Physics. I also could discuss the Space Shuttle and space flight in general.


I have a BS in Physics and an MS in Electrical Engineering. I am retired now. My professional career was in Electrical Engineering with considerable time spent working with accelerometers, gyroscopes and flight dynamics (Physics related topics) while working on the Space Shuttle. I gave formal classroom lessons to technical co-workers periodically over a several year period.
