In summary, in N=1 SUSY, each boson has a fermionic partner and an auxiliary field. When N>1, the number of superpartners for a given boson or fermion is N. For example, for N=2, there are 2 Weyl fermions and 4 fermionic degrees of freedom. This can be achieved with either 2 complex scalar fields (Hypermultiplet) or 1 complex scalar field and 1 massless gauge field (Vector Multiplet) to maintain supersymmetry.

I am sorry if the question is naive. In N=1 SUSY, for every boson we have a fermionic partner (and an auxilliary field) and vice-versa. When N>1 how many superpartners do we have given a boson (or a fermion)? Is it N?

N is the number of fermions in a given multiplet (for linearly realized SUSY, but that's a technicality).

Ex: for N=2, there are 2 (Weyl) fermions and therefore 4 (onshell) fermionic degrees of freedom. therefore you can either have 2 complex scalar fields (called a "Hypermultiplet"), or 1 complex scalar field and one massless gauge field (called a "Vector Multiplet") to make it supersymmetric.

etc.
 

1. What is N=1 SUSY?

N=1 SUSY (supersymmetry) is a theoretical framework in particle physics that proposes a symmetry between fermions and bosons. It suggests that for every known boson (particles with integer spin) there is a corresponding fermion (particles with half-integer spin) and vice versa.

2. How many superpartners are predicted for a boson/fermion in N=1 SUSY?

In N=1 SUSY, one boson and one fermion are predicted to have a superpartner. For example, the electron (fermion) would have a superpartner called the selectron (boson).

3. Why is N=1 SUSY important?

N=1 SUSY is important because it provides a solution to some of the problems in the Standard Model of particle physics. It can help explain the hierarchy problem, dark matter, and the unification of fundamental forces.

4. Is there any evidence for N=1 SUSY?

Currently, there is no direct evidence for N=1 SUSY. However, some indirect evidence has been found through experiments at the Large Hadron Collider (LHC) and other particle accelerators. Further research and experiments are needed to confirm its existence.

5. What are the implications of N=1 SUSY?

If N=1 SUSY is proven to be true, it would have significant implications for the field of particle physics. It would provide a deeper understanding of the fundamental building blocks of the universe and could lead to the discovery of new particles and forces. It could also have implications for cosmology, as it could help explain the origins of dark matter and the early universe.
