Transcript

  • 1. KLS GOGTE INSTITUTE OF TECHNOLOGY Department of Physics Presents: Seminar on: “THE GOD PARTICLE”
  • 2. ROHIT AGRAWAL ROSHNI NAIK ROJA B RATNA MATH PREPARED BY:
  • 3. Let’s Begin...... IF GOD EXITS... THEN WHY NOT GOD PARTICLE!!
  • 4. “CHALLENGE OF PARTICLE PHYSICS”
  • 5. “GOD-PARTICLE” KNOWN AS “HIGGS BOSON”
  • 6. Let’s HIGGS BOSON  In the Standard Model, the Higgs particle is a boson, a type of particle that allows multiple identical particles to exist in the same place in the same quantum state.  It has no spin, electric charge.  Is part of a Higgs mechanism that gives mass to everything .  Is the last missing piece of the Standard Model for particle physics  The Higgs particle creates a Higgs field* that permeates space time.  *Higgs field: Has the unusual property of a non-zero amplitude in its ground state; i.e. a non-zero vacuum expectation value.

  • 8. Guyzz…Who iz Higgs? Yes, this is Peter Higgs and he did propose the existence of the Higgs boson(at CERN). “ D fatty one!! ”
  • 9. The men behind gauge symmetry breaking Peter Higgs Francois Englert Robert Brout The Higgs particle is named after the British theorist Peter Higgs who along with Robert Brout and François Englert theorized its existence in 1964. HISTORY The Higgs boson is often referred to as the "God particle" by individuals outside the scientific community, from the title of a book on the Higgs boson and particle physics by Nobel Physics prize winner Leon Lederman.
  • 10. WHY IS “HIGGS” .. SO IMPORTANT ???  The Higgs is part of many theoretical equations underpinning scientists' understanding of how the world came into being.  It opens the possibility to potential new discoveries including a theory known as "super-symmetry"  How certain particles acquire mass. IF UNIVERSE IS ANSWER, “HIGGS BOSON” WAS THE QUESTION!!!!
  • 11. PRODUCTION OF HIGGS BOSON  A 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(LARGE HADRON COLLIDER)
  • 12. The most common expected processes for Higgs boson production are: Gluon fusion Higgs Strahlung Top fusion Vector boson fusion
  • 13. BASIC PARTS OF LHC
  • 14. Basic details about LHC The Large Hadron Collider at CERN in Switzerland, Built in a 27 km tunnel under the ground near Geneva It was designed to collide two beams of protons, initially at energies of 3.5 TeV per beam (7 TeV total),
  • 15. Part of the LHC, in its tunnel at CERN (European Center for Nuclear Research) near Geneva, Switzerland, on May 31, 2007.
  • 16. Middle part of LHC
  • 17. The globe of the European Organization for Nuclear Research, CERN, illuminated outside Geneva, Switzerland, on March 30, 2010.
  • 18. Civil Engineering in the ATLAS cavern. This cavern that will eventually house the ATLAS experiment, part of the LHC at CERN. February 22, 2000.)
  • 19. CAUTION “JUST NEXT 3 SLIDES “ WATCH IT CAREFULLY!!
  • 20. Roomful of people = scattered particles with mass Or The higgs field
  • 21. Famous person entering room = massive particle Rush in closer to be near her
  • 22. Swarm of people = group of particles = mass As d guests passes..surrounding guest gives him to momentum
  • 23. SO What’s the need of Higgs? Fundamental symmetries of nature require that all the elementary particles and force carriers are massless in an “ideal” world all elementary particles would be massless but in the real world the elementary particles have widely differing masses so the symmetry must be broken This is what the Higgs mechanism and electroweak symmetry breaking is all about
  • 24. What is symmetry breaking? Consider a smooth ball at the top of a very smooth symmetric hill The ball can roll in either direction … there is a left-right symmetry But the ball can only fall in one direction … the symmetry is broken
  • 25.
  • 26. Learning how certain particles acquire mass. Insight into cosmic inflation. Insight into energy of vacuum. Learning how symmetric breaks into within weak electroweak interaction.  link into ‘cosmological interest’ problem.
  • 27. Geneva, 4 July 2012. At a seminar held at CERN1 today as a curtain raiser to the year’s major particle physics conference
  • 28. DISCOVERY OF GOD PARTICLES WILL SOLVE MANY UNSOLVED MYSTERIES OF PHYSICS………………….!!!!!
  • 29. WHAT'S NEXT?
