The Standard Model of particle physics is a way to understand the tiniest building blocks of our universe. Scientists have tested it many times over the years, and the results have confirmed its predictions about particles and how they interact. Here are some important experiments that support the Standard Model:
Electron-Positron Collisions: At places like the Large Electron-Positron Collider (LEP) in Switzerland, scientists crashed together beams of electrons and positrons. When these particles collided, they created a variety of new particles that the Standard Model predicted would exist. The measurements of how often these particles were created and their energy levels matched what scientists expected.
Finding the Higgs Boson: One of the biggest discoveries came in 2012 at the Large Hadron Collider (LHC). Scientists found a particle called the Higgs boson. This particle is really important because it helps other particles gain mass through something known as the Higgs field, which is part of the Standard Model. The Higgs boson was found to have a mass of about 125 GeV/, which is what scientists had predicted.
Deep Inelastic Scattering: Researchers at the Stanford Linear Accelerator Center (SLAC) conducted experiments to look deep inside protons using very high-energy electrons. These tests showed that quarks (which are smaller parts of protons) exist, and they also provided strong evidence for gluons. Gluons are particles that help hold quarks together, and they are important for the Standard Model.
Neutral Current Experiments: In the 1970s, the Gargamelle collaboration found weak neutral currents. This discovery helped to confirm parts of the electroweak theory in the Standard Model, which explains how weak nuclear force works.
These experiments show that the Standard Model makes sense and does a good job of predicting how particles interact. It has helped shape our basic understanding of how the universe works.
