  2. Introduction • The Standard Model. • Introduction about Higgs Boson. • Higgs Mechanism. • The Large Hadron Collider. • Higgs Boson and Big Bang.

  3. The Standard Model The Standard Model of particle physics is a theory concerning the electromagnetic, weak, and strong nuclear interactions, which mediate the dynamics of the known subatomic particles

  4. Introduction about Higgs boson When you get on the scale in the morning, you may be hoping that it registers a smaller number than the day before -- you may be hoping that you've lost weight. It's the quantity of mass in you, plus the force of gravity, that determines your weight. But what determines your mass?

  5. why some fundamental particles have mass? The Higgs boson (or Higgs particle) is a particle that gives mass to other particles. Peter Higgs was the first person to think of it, and the particle was found in March 2013. It is part of the Standard Model in physics

  7. Higgs Particle the Higgs particle is a boson with no spin, electric charge, or color charge. It is also very unstable, decaying into other particles almost immediately. Bosons are particles responsible for all physical forces except gravity . with a mass between 125 and 127 GeV/c2

  8. Higgs Mechanism the Higgs mechanism is a kind of mass generation mechanism, a process that gives mass to elementary particles. According to this theory, particles gain mass by interacting with the Higgs field that permeates all space

  9. Summary of Mechanism The Higgs mechanism is a mathematical model devised by three groups of researchers in 1964 that explains why and how gauge bosons could still be massive despite their governing symmetry. It showed that the conditions for the symmetry would be 'broken' if an unusual type of field happened to exist throughout space, and then the particles would be able to have mass

  10. Spontaneous Symmetry Breaking

  11. The Large Hadron Collider The Large Hadron Collider (LHC) is the highest-energy particle collider ever made and is considered as "one of the great engineering milestones of mankind, with the aim of allowing physicists to test the predictions of different theories of particle physics and high-energy physics, and particularly prove or disprove the existence of the theorized Higgs particle

  12. The Large Hadron Collider • Higgs particle can be produced much like other particles that are studied, in a particle collider. This involves accelerating a large number of particles to extremely high energies and extremely close to the speed of light, then allowing them to smash together. Protons and lead ions (the bare nuclei of lead atoms) are used at the LHC. In the extreme energies of these collisions, the desired esoteric particles will occasionally be produced and this can be detected and studied

  13. The most common expected processes for Higgs boson production are:

  14. Technical aspects and mathematical formulation • The Higgs part of the Lagrangian is: • which give masses to the W and Z bosons:

  15. What would the world look like without the Higgs boson or a similar particle? You wouldn’t recognize the world. Without the Higgs boson or something like it giving mass to the basic building blocks of matter, electrons would zip about at the speed of light. They would not form unions with protons or other would-be nuclei to make atoms. No atoms means no chemical reactions, no molecules, no ordinary matter as we know it, no template for life. We would not exist

  16. Big Bang • At the instant of the Big Bang, the universe was comprised of particles of pure energy. • Milliseconds after the event, the universe cooled and the Higgs field developed. • Particles began to acquire mass as they cooled, slowed down, and moved through the newly created Higgs field. Particles lost kinetic energy and gained mass (E=mc2) • Particle accelerators attempt to recreate the original conditions of the Big Bang.
