I am trying to understand the analogy between a particle resonance and the resonance in a driven, damped classical oscillator.(adsbygoogle = window.adsbygoogle || []).push({});

I guess I should first ask for a clear definition of a particle resonance - is this just an excited state which decays quickly?

I understand that the KG equation which all quantum fields obey is just the equation for the harmonic oscillator. I don't understand how exactly particle resonances are analagous to resonance in the classical harmonic oscillator - could someone explain please?

Thanks
