To find a new particle, the energy and momentum of the (decayed) particles are measured(adsbygoogle = window.adsbygoogle || []).push({});

Evaluate the expression m^2 = E^2 - p^2 and plot a histogram.

I just don't understand why there is a resonance particle if there is a peak in the histogram.

Is it because the probability is very high and we regard it as a particle ??
