Can we find EM radiation in charged particle's decays?

[ORF]

Hello.

I was taught that a charge which changes its velocity must radiate (at least, in classical electrodynamics).

Let's consider a charged particle which decays into another charged particle (and, maybe, others neutral particles; but not photons). In this case, can we find electromagnetic radiation?

I found a particular example*,
http://en.wikipedia.org/wiki/Bremsstrahlung#Beta_decay
but I wonder if this a general feature of charged particle's decays.

If this question is already answered in this forum, just tell me, and I will delete this thread.

Thank you for your time :)

(at least, in classical electrodynamics).

In classical physics, indeed.

Let's consider a charged particle which decays into another charged particle (and, maybe, others neutral particles; but not photons). In this case, can we find electromagnetic radiation?

If you explicitely rule out photons as decay product, then we cannot find photons.

Bremsstrahlung is not a particle decay.

Hello.

Wikipedia's article says that exist "radiation from the creation of a charged particle". Maybe the first question I should have made is: can we find bremsstrahlung in charged particle's creations/annihilations?

then we cannot find photons.

I put the idea into the wrong words. Let's take one example: the beta-decay itself doesn't involve photons, but they appear as Bremsstrahlung.

My (reformulated) doubt is: every charged-to-charged particle's decay involve Bremsstrahlung?

Thank you for your patience and time :)

That can be called Bremsstrahlung as well, right. I thought of the process of electrons in matter in post 2.

every charged-to-charged particle's decay involve Bremsstrahlung?

At least not always in a way particle detectors could see it. Very low-energetic photons... could be.

Hello.

Ok, that was what I thought. Is there any book/link which explains this issue? I would like further information :)

Thank you for your time :)
