My experience with the Demystified series is limited to two books, QFT which is useless junk in my opinion, and SUSY which is not. The author of the SUSY book is a PF member.waht said:

Supersymmetry is a theoretical concept in physics that proposes a symmetry between two types of fundamental particles: bosons and fermions. It is important because it can help explain some of the unanswered questions in the Standard Model of particle physics, such as the hierarchy problem and the existence of dark matter.
Supersymmetry is a key component of string theory, which is a theoretical framework that attempts to unify all the fundamental forces of nature. In string theory, supersymmetry is necessary in order to maintain mathematical consistency and to solve some of the issues that arise in the theory.
No, supersymmetry has not been proven experimentally. Despite many efforts to detect supersymmetric particles, no direct evidence has been found so far. However, some indirect evidence has been observed, such as the fact that the predicted mass of the Higgs boson is close to the value required by supersymmetry.
If supersymmetry is discovered, it would provide a deeper understanding of the fundamental particles and their interactions. It could also potentially explain the existence of dark matter and provide a framework for unifying all the fundamental forces of nature. Additionally, it could help solve some of the current mysteries in physics, such as the hierarchy problem and the origin of mass.
Yes, there are some criticisms and challenges to supersymmetry. For example, some argue that the lack of evidence for supersymmetric particles could suggest that the theory is incorrect. Others point out that supersymmetry introduces many new, unobserved particles, which goes against the principle of simplicity in scientific theories.
