Discussion Overview

The discussion revolves around the evidence for dark matter, specifically focusing on the compatibility of data from different experiments such as CoGeNT, DAMA/LIBRA, XENON100, and CDMS. Participants explore the implications of recent findings and the credibility of the teams involved in the research.

Discussion Character

  • Debate/contested
  • Exploratory
  • Technical explanation

Main Points Raised

  • Some participants suggest that evidence for dark matter was present but overlooked, citing a team of Italian physicists who initially reported it.
  • Others caution against premature conclusions, noting that the region where CoGeNT and DAMA agree has been excluded by XENON100 and possibly CDMS.
  • A participant references a review by Dan Hooper and Chris Kelso, indicating that their analysis supports compatibility between CoGeNT and DAMA/LIBRA data, particularly if certain conditions regarding phase peaks are met.
  • Concerns are raised about the credibility of the DAMA team due to their refusal to release data for external analysis, which contributes to skepticism among some participants.

Areas of Agreement / Disagreement

Participants express disagreement regarding the interpretation of the data and the implications for dark matter evidence. While some see potential confirmation of findings, others emphasize the need for caution and further validation from other experiments.

Contextual Notes

There are unresolved issues regarding the exclusion of certain data regions by XENON100 and CDMS, as well as the implications of the DAMA team's data withholding on the overall credibility of their findings.

It seems that we had the evidence, but no one had noticed except a team of Italian physicists who weren't taken seriously.

At last, the data was confirmed by another team.

Let's not get ahead of ourselves. The region where CoGeNT and DAMA agree has been excluded by XENON100 and I think maybe CDMS.
 
From the link:

Dan Hooper at the Fermi National Accelerator Laboratory and Chris Kelso from the University of Chicago review the data from CoGenT and DAMA/LIBRA and say they are compatible with each other. "If the true phase peaks in early May, this would represent a modulation consistent with that reported by the DAMA/LIBRA collaboration," they say.

Aren't they confirming the data?
 
As I said, let's not get ahead of ourselves. The region where CoGeNT and DAMA agree has been excluded by XENON100 and I think maybe CDMS.

I agree with Vanadium 50, let's wait and see what the other experiments show.
One of the reasons that the DAMA team is not taken more seriously is that they refuse to release their data for others to see and analyze. This tends to make people skeptical.
