What research have you done on this so far? What have you found?

What research have you done on this so far? What have you found?

I found exchange operator anticommutes with charge conjugation, by making use of so4 group emebdiings into higher dimensions, eg 4n-dimensions. The natural question is whether it contradicts / get support from available experimantal data. I was not able to find relevant experiments. Then ask more.

What experiment we have today with many body antiparticle states? What experiment we have today with interacting antiparticles? To what extent testing antimatter many body effects is on the roadmap of the experiemntal physics?

Let's ask experimental physics community to put efforts and budgets on producing and storage higher antimatter densities. Let see if readers can propose more experiments with antimatter, than what we see posted today by institutional roadmaps.

There was recently the experimental confirmation that antimatter falls down. That was using anti hydrogen, so that is two body.

Let see if readers can propose more experiments with antimatter, than what we see posted today by institutional roadmaps.

The institutional roadmaps you mention are generally scheduled at capacity. So adding more experiments would require eliminating some. Which specific experiments would you eliminate?

What for?

 

[WeeWillieWinkie]

What for?

1st to avoid counterproductive spending on unemployment and gambling. 2nd, antimatter experimental physics is a bit boring now; there is a good chance to find new physics in interactive antimatter. systematic study of antimatter fundamental laws is ok too, it seems we are mostly done with one-anti-particle effects.

Setting the priorities of the institutions you mention is way, way beyond anything PF is set up to discuss.

That is a silly and false dichotomy. The spending alternatives are not between antimatter research on one hand and between unemployment and gambling on the other. Your response is not an indication of an intention to have an informed discussion on this topic.

As I mentioned in my earlier reply the actual alternatives are between the already planned experiments and some alternative experiments. These decisions are made by multiple deeply qualified experts with a view towards maximizing the potential gain given the finite resources.

I know that I don't have the expertise to make a better allocation of resources, and I suspect that there is only one or two members here that are qualified to even weigh in on those questions. Those one or two members, not coincidentally, probably already have weighed in.

2nd, antimatter experimental physics is a bit boring now; there is a good chance to find new physics in interactive antimatter. systematic study of antimatter fundamental laws is ok too, it seems we are mostly done with one-anti-particle effects.

Maybe you should speak to Bill Nye instead. He might help make it less boring for you.

Thread closed.
