Discussion Overview

The discussion centers on the nature of neutrino collisions, specifically what occurs when two neutrinos collide, including the potential for energy release and the mechanisms of detection. It encompasses theoretical aspects related to particle physics and the Standard Model, as well as practical considerations regarding neutrino detection.

Discussion Character

  • Exploratory
  • Technical explanation
  • Debate/contested

Main Points Raised

  • One participant questions how neutrinos can be detected and speculates on the likelihood and consequences of neutrino collisions, suggesting that they may not release energy due to their lack of charge.
  • Another participant emphasizes the importance of the Standard Model, noting that it describes neutrino interactions and suggests looking into "weak interactions" as the relevant mechanism for neutrinos.
  • A different participant states that if neutrinos collide, they would undergo weak interactions, which could be either elastic or inelastic, with elastic scattering being less noticeable. They also mention that the interaction cross section increases significantly as the collision energy approaches the weak scale.

Areas of Agreement / Disagreement

Participants express differing views on the nature of neutrino collisions and their implications, with no consensus reached regarding the specifics of energy release or the detection of such events.

Contextual Notes

There are limitations in the discussion regarding the assumptions about neutrino interactions and the conditions under which they may or may not release energy. The discussion also reflects a dependency on the definitions of weak interactions and the context of collision energy.

I was thinking about how particles collide and how we can detect it but how do we do the same for neutrinos? We can’t detect them without big water detectors and the chances of two neutrinos colliding is probably near zero but what does happen when they do collide? Do they release energy? Do they don’t release energy? I’m assuming for now that they don’t release energy since they have no charge so if anyone can provide a answer that would be great!

All due respect I’d rather get answers from professionals in said field or people who know the answer to a question rather than fully relying on a AI response from google, sometimes it doesn’t explain it so it’s better to have a real person explain it in my opinion. But thank you for answering my question.

Well, there is this very successful theory called the Standard Model. It describes interactions between elementary particles, including neutrinos. You might want to check it out. Look specifically for "weak interactions", which are the only kind of interactions neutrinos take part in. The image posted by @phinds sums it up nicely.

If neutrinos collide they would undergo a regular weak interaction. This can either be elastic or inelastic depending on energy. An elastic scatter would not be very noticable.

The cross section of interaction would increase manifold if the com energy approaches the weak scale.
