What is Supersymmetry and How is it Used in Physics?

[Focus]

Hello,

My first post in the forums so please excuse me if there is already a post on this (I couldn't find one).

I am not very technical in physics so can you please use simple language :shy: . I am not entirely sure on the concept of supersymmetry, I know stuff like partner of an electron is selectron and partners are always heavier, and the change of spin from an electron to a selectron is a half. The thing I am not very clear on is how/why they believe in this and also how can they predict the mass and the spin of the partners? I am assuming they just didn't randomly say selectron has 0 spin.

Thanks in advance

Welcome to Physics Forums. A good introduction can be found in Wikipedia:

In short, it comes when you build supermultiples, in the same way that for instance isospin multiplets. Group theory stuff.

Ok thanks for the help
