Discussion Overview

The discussion centers around the possibility that a newly observed particle at CERN could be a massive graviton, exploring its implications and characteristics. Participants consider various theoretical frameworks, including the nature of the particle as a scalar, vector, or tensor boson.

Discussion Character

  • Exploratory
  • Debate/contested
  • Technical explanation

Main Points Raised

  • One participant suggests that the new particle could be a massive tensor boson, specifically a massive graviton, and questions its plausibility.
  • Another participant notes that while spin 2 is not ruled out, the existence of massive gravitons would imply a need for multiple gravitons to account for gravity's long-range effects, suggesting at least one must remain massless.
  • A different viewpoint indicates that evidence from announcements points towards the boson being scalar, while still acknowledging the intriguing idea of multiple massive gravitons.
  • One participant proposes the possibility of a massive scalar partner to a massless tensor graviton, referencing literature on the Higgs as a radion.

Areas of Agreement / Disagreement

Participants express differing views on the nature of the new particle, with no consensus reached regarding whether it could be a massive graviton or what its characteristics might be.

Contextual Notes

There are unresolved questions regarding the classification of the new particle as scalar, vector, or tensor boson, and the implications of massive versus massless gravitons remain unclear.

Hi PF.

I was wondering, if the newly observed particle @ CERN, could be a massive tensor boson, like a massive graviton. I have not been able to find out, whether ATLAS or CMS have determined if the new particle is a scalar, vector or tensor boson, so I thought it would be interesting, if the new particle would be a massive graviton.

Would it be plausible, that the newly discovered boson would be a massive graviton?

Spin 2 is not ruled out yet.
However, massive gravitons would be strange - do you propose gravity with several different gravitons? If there are gravitons, at least one has to be massless to produce the long-ranging effects of gravity we experience.
 
I was listening to their announcement and the evidence seems to point to the boson being scalar. The idea of multiple massed Gravitons is an interesting idea though.
 
It could be a massive scalar partner of a massless tensor graviton. e.g. see papers on Higgs as radion.
