In the Standard Model fermions interact via exchanges of massless (virtual) spin-1 particles. Fermions are turned into a boson. How is that different from the SUSY transformation that turns fermions into bosons?
Fermions are not turned into bosons in the exchange in the SM (unless in s-channel where two fermions combine into a generally off-shell boson).Lapidus said:In the Standard Model fermions interact via exchanges of massless (virtual) spin-1 particles. Fermions are turned into a boson

See 7.5 of Stephen Martin. When global susy is spontaneously broken, the resulting goldstino can transform particles to their superpartners. In local susy, i.e. supergravity, the gravitino has this property.arivero said:what happens with the generator of supersymmetry?
Fermions and bosons are two types of particles in the Standard Model of particle physics. Fermions are particles with half-integer spin, such as quarks and leptons. Bosons are particles with integer spin, such as photons and W and Z bosons.
Vertices are points where particles interact with one another in the Standard Model. These interactions are described by Feynman diagrams and are crucial for understanding the behavior of particles and their interactions.
Supersymmetry is a theoretical framework that proposes a new symmetry between fermions and bosons. It is important because it provides a solution to several problems in the Standard Model, such as the hierarchy problem and the lack of a dark matter candidate.
Fermions, bosons, and vertices are fundamental building blocks of the Standard Model and play a crucial role in understanding the behavior of particles and their interactions. Studying these concepts allows scientists to make predictions and test the validity of the Standard Model.
Currently, scientists are still exploring the behavior of fermions, bosons, and vertices in the Standard Model without SUSY. Many experiments, such as those at the Large Hadron Collider, are searching for evidence of new particles or interactions that may provide a better understanding of these concepts. However, the Standard Model without SUSY remains a well-tested and successful theory in explaining the behavior of particles.
