Is supersymmetry part of string theory or does it have a place in the standard model

I don't think this is accurate. String theory is unstable without supersymmetry. While you can write down on paper a string theory model which doesn't require supersymmetry (bosonic string theory), that model has an unstable vacuum.PeterDonis said:You can combine string theory with supersymmetry to get superstring theory, but there is also string theory without supersymmetry, and there are supersymmetric theories that are not based on string theory.
There was somebody who presented the idea a few years before, but it was never really investigated in full. The first time that supersymmetry became widely-discussed in the physics community was in the context of string theory. It is possible to come up with supersymmetric theories which make no reference to string theory, of course, but the primary motivation for its development was string theory.Chronos said:Supersymmetry originated outside of string theory, but, was rapidly embraced by the string community because it suppresses the infinities and other embarrassments, like imaginary energy, that keep popping up in theory. Naturally, stringophiles wasted little time claiming supersymmetry was actually predicted on the back of one or more of their 10500 envelopes. For a discussion of supersymmetry, see https://arxiv.org/abs/hep-ph/0002232, Supersymmetry Phenomenology.

Supersymmetry is a theoretical concept in physics that proposes the existence of a fundamental symmetry between particles with different spin, such as bosons and fermions. It is also known as SUSY and is a key aspect of many unified theories, including string theory.
Supersymmetry is an important component of string theory, as it helps to address some of the issues and limitations of the Standard Model of particle physics. In string theory, supersymmetry allows for the unification of quantum mechanics and general relativity, and provides a way to incorporate gravity into the theory.
Supersymmetry is a theoretical concept and has not been conclusively proven through experiments. However, there is some evidence that supports its existence, such as the Higgs boson discovery, which is predicted by supersymmetry.
While there is no direct evidence for supersymmetry, some experiments, such as the Large Hadron Collider (LHC), have been conducted to search for particles that could confirm its existence. The lack of evidence from these experiments has led to some skepticism about the validity of supersymmetry.
If supersymmetry is proven to be a part of string theory, it would have significant implications for our understanding of the fundamental laws of the universe. It would also provide a more complete and unified theory of the universe, potentially leading to new discoveries and advancements in physics.
