Did the LHC prove string theory?

However, string theorists have pointed out that a firm prediction of string theory is the existence of extra space-time dimensions. In a space which is curved into a higher dimension, the apparent value of pi can deviate from that seen in real life. And thus the LHC may have proved that they were right all along.

How does supersymmetry explain dark matter?

Supersymmetry predicts that each of the particles in the Standard Model has a partner with a spin that differs by half of a unit. So bosons are accompanied by fermions and vice versa. The Standard Model alone does not provide an explanation for dark matter.

Why is there no supersymmetry in the LHC model?

There is nothing in supersymmetric extensions of the standard model which prevents theorists from raising the masses of the supersymmetric partners until they are out of the reach of the LHC. This is also the reason why the no-show of supersymmetry has no consequences for string theory.

Why is there no supersymmetry in string theory?

This is also the reason why the no-show of supersymmetry has no consequences for string theory. String theory requires supersymmetry, but it makes no requirements about the masses of supersymmetric particles either. Yes, I know the headlines said the LHC would probe string theory, and the LHC would probe supersymmetry.

What can we learn from the LHC?

But the LHC, despite not finding supersymmetry or extra dimensions or black holes or unparticles or what have you, hastaught us an important lesson. That’s because it is clear now that the Higgs mass is not “natural”, in contrast to all the other particle masses in the standard model.

What are the consequences of supersymmetry in physics?

The consequences for supersymmetry itself are few. The reason is that supersymmetry by itself is not a very predictive theory. To begin with, there are various versions of supersymmetry. But more importantly, the theory doesn’t tell us what the masses of the supersymmetric particles are.
