CERN experiment discovers five new particles
Just to give a bit more context:<p>* These are not elementary particles.
* It was predicted for a long time that these composite particles should exist. So it is not &quot;new&quot; in the sense that it was unexpected, but we finally have the resolution (energy, luminosity etc.) to detect these with statistical significance.
* These belong to the same class as protons and neutrons - these are hadrons made with multiple quarks.<p>Here&#x27;s a super simple overview of Quantum Field Theory &amp; Particle Physics:<p>Everything is made of force fields and matter fields.<p>* We discovered that force fields (i.e. electromagnetism) is quantized, giving rise to quantum mechanics etc.<p>* Matter fields are also quantized, hence their excitations behave like discrete particles - the ones we observe at the atomic scale, for instance.<p>* In hindsight, we should&#x27;ve been able to predict this after E = mc^2 telling us energy &lt;&gt; matter,  thus if energy is quantized so should matter.
