Has Anti-beta decay been observed?
I am looking for references or resources regarding the transition of an anti-neutron through weak decay, into an anti-proton, positron, and electron-neutrino.
Have such studies been conducted or ...

Does the collision of a neutron and anti-neutron produce energy?
Following up on this post: Anti-Particle of Neutron, one very important part of it is unanswered. If a neutron collides with an anti-neutron, will it violently explode in a flash of energy? The ...

Can neutronium, (as in the exotic -onium atom composed of $n\bar n$ and not the degenerate matter kind) exist?
First off I'd like to say yeas I know what neutron-degenerate matter aka neutronium is and how it's likely what's inside neutron starts, this isn't what the wuestion is abount. I am referring to an -...

Experimental proof for the antineutron
An answer to the question How detectors in particle accelerators can differentiate neutrons from antineutrons do not show that an antineutron measurement was successful. The answers are from 2014 and ...

Is the neutron its own antiparticle? [duplicate]
I have seen multiple claims that the neutron is its own antiparticle. However surely the antiparticle of the neutron would have a baryon number of -1 because it would consist of three antiquarks, each ...

Can coherent superpositions of a neutron and antineutron exist?
In my recent post I learned that electric charge is always conserved in contrast to strangeness quantum number, which limits the types of Hadrons that can be build. Furthermore, also different masses ...

How neutron can have an antiparticle since it have zero charge?
Antiparticles are defined as fundamental particles having the same mass but opposite charge.
Now, a neutron has a particular mass (say m) , but zero charge ( =0). Its antiparticle should have mass=m ...

How detectors in particle colliders can differentiate neutrons from antineutrons?
Their mass is the same. None of them interacts with EM fields. And their decay (around 1000s) is far too slow to see their decay products yet in the detector.
How is it then possible to differentiate ...

Anti-neutrons, anti-quarks, isospin: What is observed and what is derived?
I would be a little more restrained with the existence of antineutrons. First at all - if I understood right - the existence of antiquarks is hypothetical. If one not agree with this please refer to ...

If one is talking about antineutron production, what is the charge exchange?
In this question was given the antineutron production in the way
$$ p + \bar{p} \rightarrow n + \bar{n}. $$
Internet search gives one source only where the charge exchange is mentioned. They talk ...

How to create antineutrons?
Creating a beam of antiprotons allows to create antineutrons by charge exchange. How does this exchange work?
The question pops up after the question "Is there a strong evidence of antineutron ...

Is there a strong evidence of antineutron existance?
Wikipedia explains:
The antineutron was discovered in proton–proton collisions at the Bevatron (Lawrence Berkeley National Laboratory) by Bruce Cork in 1956, one year after the antiproton was ...

Neutron to antiproton decay
Would it be possible for a neutron to lose a positron and become an antiproton?
Or would would it need to be the decay of an antineutron to antiproton instead?

Will an anti-neutron annihilate a regular neutron even though they have no charge
Since neutrons have no electric charge will an anti-neutron annihilate when it comes into contact with a regular neutron as protons and anti-protons do? if so what causes it to annihilate?
