Discussion Overview

The discussion revolves around the relationship between inflation and supersymmetry breaking, particularly focusing on the production of gravitinos during the early universe's reheating phase following inflation. Participants explore whether the dynamics of the inflaton oscillating about the potential minima can be likened to symmetry breaking.

Discussion Character

  • Exploratory, Technical explanation, Debate/contested

Main Points Raised

  • One participant suggests that the oscillation of the inflaton at the end of inflation may be analogous to symmetry breaking, particularly in relation to gravitino production.
  • Another participant points out that gravitinos and gravitons have not been observed, raising a question about the validity of the claims regarding their production.
  • A third participant acknowledges the lack of observational evidence but asserts that if supersymmetry (SUSY) exists, gravitinos would indeed be produced after inflation.
  • A fourth participant provides a reference to an article on the topic, indicating a lack of familiarity with SUSY but suggesting that the article may offer additional insights.

Areas of Agreement / Disagreement

Participants express differing views on the observational status of gravitinos and the implications for the discussion on inflation and SUSY breaking. There is no consensus on the analogy between inflaton dynamics and symmetry breaking.

Contextual Notes

Some assumptions regarding the existence of SUSY and the implications of gravitino production remain unresolved. The discussion also reflects a dependence on theoretical models that have not been empirically validated.

Hi
I know that gravitninos are produced in the Early Universe in reheating (after inflation), is this because the end of inflation/reheating period where the inflaton is oscillating about the minima of the potential is analogous to symmetry breaking?
 
Space news on Phys.org
You realize that gravitinos and gravitons have not been observed right?
 
yes but if susy does exist, gravitinos would be produced after inflation.
