Is the Standard Model wrong?
The Standard Model is inherently an incomplete theory. There are fundamental physical phenomena in nature that the Standard Model does not adequately explain: About 26\% should be dark matter, which would behave just like other matter, but which only interacts weakly (if at all) with the Standard Model fields.
Is Standard Model correct?
The Standard Model is a thing of beauty. It is the most rigorous theory of particle physics, incredibly precise and accurate in its predictions. Despite its great predictive power, however, the Standard Model fails to answer five crucial questions, which is why particle physicists know their work is far from done.
How does supersymmetry solve the hierarchy problem?
Supersymmetry can explain how a tiny Higgs mass can be protected from quantum corrections. Supersymmetry removes the power-law divergences of the radiative corrections to the Higgs mass and solves the hierarchy problem as long as the supersymmetric particles are light enough to satisfy the Barbieri–Giudice criterion.
Does the Higgs boson complete the Standard Model?
Detecting the Higgs boson completed the Standard Model of particle physics, a theory describing all the known fundamental particles and how they interact.
Is there evidence for supersymmetry?
To date, no evidence for supersymmetry has been found, and experiments at the Large Hadron Collider have ruled out the simplest supersymmetric models.
Is supersymmetry still possible?
In particle physics, a supersymmetric extension of the Standard Model is a possible candidate for physics beyond the Standard Model, and in cosmology, supersymmetry could explain the issue of cosmological inflation. Supersymmetry has not been experimentally verified.
Why is the hierarchy problem a problem?
The hierarchy problem occurs because the fundamental parameters of the Standard Model don’t reveal anything about these scales of energy. Just as physicists have to put the particles and their masses into the theory by hand, so too have they had to construct the energy scales by hand.
