Discussion Overview

The discussion centers around the relationship between temperature and the mass of the axion particle, exploring theoretical implications and interpretations of mass in the context of particle physics.

Discussion Character

  • Exploratory, Technical explanation, Debate/contested

Main Points Raised

  • One participant questions how the mass of an elementary particle can depend on temperature, noting that temperature is related to the average kinetic energy of particles.
  • Another participant expresses confusion over the concept of mass, suggesting that mass typically refers to rest mass and that temperature should not affect it, while acknowledging their uncertainty.
  • A different viewpoint suggests that temperature relates to an average of quantum states, proposing that higher temperatures correspond to higher energy and thus higher mass equivalence.
  • Another participant mentions that the axion is a Nambu-Goldstone boson with a mass that is dynamically determined and evolves during the inflationary period of the universe, referencing a review for further reading.

Areas of Agreement / Disagreement

Participants express differing views on the relationship between temperature and mass, with no consensus reached on the implications of temperature for the mass of axions or the nature of mass itself.

Contextual Notes

There is ambiguity regarding the definitions of mass being discussed, including rest mass and relativistic mass, as well as the implications of temperature on these concepts.

Axion mass is said to depend on temperature. I don't understand this. Can somebody explain how the mass of an elementary particle depend on temperature at all? Temperature is the average kinetic energy of particles. So what does it have anything to do with the mass of an elementary particle?

I think that there is considerable confusion over "mass". As far as I understand it, mass only refers to the rest mass of something usually. Trying to add in different types of mass such as relativistic mass is confusing and does nothing to help anything. As far as I am concerned the temp of an object has nothing to do with the mass. (However I am not sure on this, as I said there is much confusion and misunderstanding.)
 
Temperature is an average of quantum states. A laser pointer beam has a temperature of over 1000K for a tiny fraction of a second. Energy and mass are the same so higher temperature means higher energy and higher mass equivalence.
 
memento, The axion is a Nambu-Goldstone boson whose mass is dynamically determined, and evolves during the inflationary period of the universe. For a good recent review, see
