Can string theory exist without supersymmetry?

NO! There is a bosonic string theory which doesn’t use any supersymmetry.

Is supersymmetry related to string theory?

Supersymmetry is a specific mathematical relationship between certain elements of physics equations. It was discovered outside of string theory, although its incorporation into string theory transformed the theory into supersymmetric string theory (or superstring theory) in the mid-1970s.

Is supersymmetry proven?

To date, no evidence for supersymmetry has been found, and experiments at the Large Hadron Collider have ruled out the simplest supersymmetric models.

How small are strings in string theory?

The strings of string theory are unimaginably small. Your average string, if it exists, is about 10-33 centimeters long. That’s a millionth of a billionth of a billionth of a billionth of a centimeter. If an atom were magnified to the size of the solar system, a string would be the size of a tree.

Will supersymmetric particles appear at the Large Hadron Collider?

If the theory is correct, supersymmetric particles should appear in collisions at the LHC. At first sight, the Standard Model seems to predict that all particles should be massless, an idea at odds with what we observe around us.

Could supersymmetry replace the Higgs boson?

The extra particles predicted by supersymmetry would cancel out the contributions to the Higgs mass from their Standard-Model partners, making a light Higgs boson possible. The new particles would interact through the same forces as Standard-Model particles, but they would have different masses.

What is supersymmetry and why does it matter?

Supersymmetry is an idea that hopes to improve on the Standard Model, but it has yet to make successful predictions about the Universe in attempting to supplant the prevailing theory.

What is supersymmetry at CERN?

CERN Accelerating science. Supersymmetry. The Standard Model has worked beautifully to predict what experiments have shown so far about the basic building blocks of matter, but physicists recognize that it is incomplete. Supersymmetry is an extension of the Standard Model that aims to fill some of the gaps.
