Does Salam-Weinberg theory not work at very high energy?

In summary, Salam-Weinberg theory, also known as the electroweak theory, explains the interactions between particles at the subatomic level and has been confirmed by numerous experiments. "Very high energy" in this context refers to energies above the range that has been tested and confirmed by experiments, which is around 100 GeV (gigaelectronvolts). At very high energies, the interactions between particles become stronger and the effects of the weak nuclear force become more significant, causing the predictions of Salam-Weinberg theory to deviate from experimental results. The theory of quantum chromodynamics (QCD) is used to describe interactions between particles at very high energies, as it is a part of the standard model

Please teach me this:
It seem to me that Salam Weinberg theory of weak interaction does not work at very high energy,because weak bosons are massive and transversal at the limit q[itex]^{2}[/itex]→0.
Thank you very much in advance.

Please teach me this. Why don't you get a textbook? You have asked one hundred and thirty two one-line questions. It is surely more efficient than asking PF to essentially write you a textbook one line at a time.

Also, it wouldn't hurt you to say "thank you" once in a while.
 

FAQ: Does Salam-Weinberg theory not work at very high energy?

1) What is Salam-Weinberg theory?

Salam-Weinberg theory, also known as the electroweak theory, is a unification of electromagnetism and the weak nuclear force. It explains the interactions between particles at the subatomic level and has been confirmed by numerous experiments.

2) What is considered "very high energy" in relation to Salam-Weinberg theory?

"Very high energy" in this context refers to energies above the range that has been tested and confirmed by experiments, which is around 100 GeV (gigaelectronvolts).

3) Why does Salam-Weinberg theory not work at very high energy?

At very high energies, the interactions between particles become stronger and the effects of the weak nuclear force become more significant. This causes the predictions of Salam-Weinberg theory to deviate from experimental results.

4) Is there a different theory that explains particle interactions at very high energy?

Yes, the theory of quantum chromodynamics (QCD) is used to describe interactions between particles at very high energies. It is a part of the standard model of particle physics and is based on the strong nuclear force.

5) Are there any ongoing research efforts to improve Salam-Weinberg theory at high energies?

Yes, there are ongoing research efforts to develop a more complete theory that can accurately describe particle interactions at all energy levels. Some proposed theories, such as supersymmetry, aim to extend the standard model and provide a more comprehensive understanding of the fundamental forces of nature.
