Why is it helpful to know about the particles absent around us?

Being born abundantly in each collision of collider beams

Indeed, most of the observed matter consist of only three kinds of elementary particles: protons, neutrons and electrons. Apart from them, there are neutrinos and quanta of electromagnetic radiation — photons — in the space of the universe. Other kinds of elementary particles are present in the stars, where the temperature and density are enormous. On Earth, these unusual kinds of particles can be produced in the collision of particle beams at accelerators. The discovery of new particles confirms or denies the hypotheses, guiding the subsequent experimental studies and development of theoretical models. In addition, the properties of new particles play a key role in understanding the interactions of ordinary elementary particles, which is important for applied science and technology.

While it is not so easy to learn the properties of particles created in a physical experiment.
