Higgs, neutrinos, and standard model status

In summary, the Higgs boson is a subatomic particle that was predicted by the Standard Model of particle physics and its discovery in 2012 confirmed the existence of the Higgs field. Neutrinos are subatomic particles with very little mass and no electric charge, making them difficult to detect, but they play a significant role in astrophysical processes. The Standard Model is a theory that explains the fundamental particles and their interactions, accounting for the four fundamental forces and behavior of matter and energy at small scales. Although the Standard Model is currently the most successful theory in particle physics, it is not complete and does not account for certain phenomena. The discovery of the Higgs boson has further solidified the Standard Model, but has also

I've always understood that the "formula" for the Standard Model is SU(3) × SU(2) × U(1). Since the discovery of the Higgs boson, and observations of neutrino flavor oscillations, has that formula been revised, or is it still the same?

With the Higgs mechanism, is SU(3) × [SU(2) × U(1) broken to U(1)]. And it describes the interactions (bosons) only, not the leptons.
Neutrinos are leptons, they don't care about those symmetries in their mixing.
 

Related to Higgs, neutrinos, and standard model status

What is the Higgs boson and why is it important?

The Higgs boson is a subatomic particle that was predicted by the Standard Model of particle physics. Its discovery in 2012 confirmed the existence of the Higgs field, which is responsible for giving particles mass. This discovery was important because it completed the Standard Model and provided a deeper understanding of the fundamental building blocks of the universe.

What are neutrinos and why are they significant?

Neutrinos are subatomic particles that have no electric charge and very little mass. They are produced in nuclear reactions and can pass through matter without interacting with it, making them difficult to detect. They are significant because they play a crucial role in many astrophysical processes and their study can provide insights into the early universe.

What is the Standard Model and what does it explain?

The Standard Model is a theory in physics that describes the fundamental particles and their interactions. It explains how particles are affected by the four fundamental forces - gravity, electromagnetism, strong nuclear force, and weak nuclear force. It also explains the behavior of matter and energy at the smallest scales.

What is the current status of the Standard Model?

The Standard Model is currently the most successful and widely accepted theory of particle physics. It has been confirmed by numerous experiments and has accurately predicted the outcomes of many particle interactions. However, it is not a complete theory and does not account for phenomena such as dark matter and gravity. Scientists are actively working to further refine and expand the Standard Model.

How does the discovery of the Higgs boson impact our understanding of the Standard Model?

The discovery of the Higgs boson was a major milestone in the field of particle physics and confirmed the validity of the Standard Model. It also provided evidence for the existence of the Higgs field, which is crucial for explaining mass in the universe. However, it also raised new questions and challenges for the Standard Model, such as the hierarchy problem and the need for a more complete theory that can incorporate gravity.
