Measurements of the Self-Interaction of the Higgs

In summary, the conversation was about the search for new physics through experiments measuring the self-interaction of the Higgs. The speaker expressed confusion about the lack of information on this topic on the ATLAS website, and suggested that understanding the self-interaction of the Higgs could reveal new physics. They also requested information on how to access specific papers related to this topic. Another participant recommended using Google to locate the papers, and provided links to the freely available versions. Overall, the conversation highlights the ongoing exploration of the frontiers of physics and the use of various resources to access research.

Hello Everyone, Hope you are all enjoying learning more and more about this wonderful world of Physics!

Is it that I am missing something somewhere, but when I searched the ATLAS site to find out what experiments were planned to measure the self-interaction of the Higgs, I could see nothing! It all seems to be about verifying supersymmetry and other new theories. One would think that knowing the self-interaction of the Higgs would signal new physics definitely if it were different from that which is predicted. It would be good to hear from a senior academic on this.

Best wishes and keep on exploring the frontiers!

There is this thing called "Google". If you go to www.google.com and put in "PRD94 052002 (2016)", for example, it will return the link to the paper. It's really remarkable.

All LHC papers are freely available from the publishers, not just the arXiv.
 

1. What is the Higgs self-interaction and why is it important to measure?

The Higgs self-interaction refers to the interaction between Higgs particles themselves. It is important to measure because it helps us understand the fundamental properties of the Higgs field, which is responsible for giving particles their mass.

2. How is the self-interaction of the Higgs measured?

The self-interaction of the Higgs is measured through experiments at particle accelerators, such as the Large Hadron Collider. Scientists look for specific particle collisions that produce evidence of Higgs self-interaction.

3. What are the implications of measuring the self-interaction of the Higgs?

If the self-interaction of the Higgs is measured and found to be consistent with predictions from the Standard Model of particle physics, it would provide further evidence for the validity of this model. However, if the measurements deviate from the predictions, it could indicate the need for a new model or theories to explain the behavior of the Higgs field.

4. Are there any challenges in measuring the self-interaction of the Higgs?

Yes, there are several challenges in measuring the self-interaction of the Higgs. The self-interaction is a rare event, so it requires a large amount of data and precise measurements to observe it. Additionally, there can be background noise from other particle interactions that can make it difficult to isolate the signal of Higgs self-interaction.

5. How does measuring the self-interaction of the Higgs contribute to our understanding of the universe?

Measuring the self-interaction of the Higgs helps us understand the fundamental forces and particles that make up our universe. It also provides insights into the nature of mass and how it is generated in the universe. This knowledge can ultimately lead to a deeper understanding of the origins and evolution of the universe.
