What would happen if you managed to collide an electron with a anti matter protron?

What would happen if you managed to collide an electron with a anti matter protron?

 

Firstly - not sure you could with the electromagnetic repulsion. Secondly, I don't think you could annihilate to photons as you would need at least two particles to remain to conserve the net -2 charge. There are other properties which would also need to be conserved - remember in particle / own anti-particle annihilation all these things cancel out - well everything apart from the things that can be carried off with the photon

 

I guess that if you had enough energy inherent in the system to force them to close proximity then you would have enough for other particle creation and you would create a handful or more of short-lived particles which would cascade decay to two negatively charged stable particles

One would call this a scattering event; there would be a point of closest approach (impact parameter).

 

But you're right, they would not annihilate. That are not antiparticles of each other.

Thanks guys, I guess this would apply to a matter and anti matter neutron as well?

A matter and antimatter neutron would annihilate with each other, but not with an electron.

 

With a proton and antineutron, I'm not sure what would happen, since you have quarks and antiquarks which could potentially annihilate or recombine, possibly leaving you with a mix of photons and mesons

Anti-proton has charge -1e,

Electron has also charge -1e.

So they are repelling each other.

 

Similar like positron,pion+, repel with proton (or positively charged metal plate, electrode, if it's inside of vacuum and used to change path of particle like in mass-spectrometer/electron gun)

 

Anti-proton has Baryon Number -1, Lepton Number 0,

Proton has Baryon Number +1, Lepton Number 0,

Positron has Baryon Number 0, Lepton Number -1,

Electron has Baryon Number 0, Lepton Number +1.

 

So you have input particles with B=-1,L=+1
