Supersymmetry

In summary, supersymmetry is a theoretical framework in physics that proposes a symmetry between particles with integer spin and particles with half-integer spin. However, there is no experimental evidence to support it, leading scientists to explore alternative theories such as extra dimensions, technicolor, composite models, and string theory. These theories are being tested through particle colliders like the LHC at CERN. While these alternatives offer different explanations, they may also have drawbacks such as more complex mathematics and limitations in explaining certain phenomena. Some scientists believe that elements of these theories can coexist with supersymmetry, but more research is needed to support this idea.

Can someone comment on https://arxiv.org/abs/1703.10188 ?
If correct, it seems very important.

Finding a new exception to a key no go theorem does sound important.

1. What is supersymmetry and why do we need an alternative to it?

Supersymmetry is a theoretical framework in physics that proposes a symmetry between particles with integer spin (bosons) and particles with half-integer spin (fermions). It was originally proposed as a solution to certain problems in the Standard Model of particle physics, but so far there is no experimental evidence to support it. Therefore, scientists are exploring alternative theories that can better explain the fundamental forces and particles in the universe.

2. What are some potential alternatives to supersymmetry?

Some proposed alternatives to supersymmetry include extra dimensions, technicolor, composite models, and string theory. These theories offer different explanations for the same problems that supersymmetry aims to solve, and are actively being explored by physicists.

3. How can we test these alternative theories?

One way to test these alternative theories is through particle colliders, such as the Large Hadron Collider (LHC) at CERN. By smashing particles together at high energies, scientists can look for new particles and interactions that could support these alternative theories.

4. Are there any drawbacks to these alternative theories?

One potential drawback of alternative theories to supersymmetry is that they may require more complex mathematical frameworks and equations, which can be more difficult to test and understand. Additionally, some of these theories may also have limitations in explaining certain phenomena that are well-supported by supersymmetry.

5. Can these alternative theories coexist with supersymmetry?

Some scientists believe that elements of these alternative theories can coexist with supersymmetry, and that a combination of these theories may be necessary to fully explain the complexities of the universe. However, more research and evidence is needed to support this idea.
