I Cross Section & Mass: Is There a Relation?

Click For Summary
The discussion centers on the relationship between WIMP-nucleon cross sections and mass, emphasizing that while there is a correlation, no universal formula applies to all scenarios. Cross sections depend on mass due to factors like interaction strengths and available phase space for produced particles. Direct dark matter detection experiments estimate the expected number of dark matter particles based on local density and velocities, which influences the maximum possible cross-section calculations. The findings indicate that dark matter interactions are significantly weaker than neutrinos, complicating theories like supersymmetric WIMPs that assume calculable cross-sections. Overall, the interplay between mass and cross-section remains complex and context-dependent.

Ethan Siegel is not a reliable source. On multiple occasions he has made an error, I reported it to him, he acknowledged the error, and then didn't correct it. He writes "sciency entertainment" not science.

In any event, I think this thread can be closed. You asked a question, got an answer, and did not accept the answer. What purpose is there in going around again and again and again?
As a matter of fact I also got into an argument with him about an error, and while he acknowledged the error privately, he didn’t correct it in his blog.
Anyways, that’s besides the point. I didn’t say I didn‘t accept the answer…I am just exploring the issue. I was about to request closing the thread myself, since someone else is extending it unnecessarily.
