Presentation Transcript

  1. What in the name of God is the Higgs boson? SubhendraMohanty Physical Research Laboratory

  2. Peter Higgs, 2012.

  3. S.N.Bose, Dhaka 1921

  4. Elementary particles Name: electron Spin : ½ Charge: - 1 Mass: 0.51 MeV

  5. Interactions between electrons R.P.Feynman takes place by exchange of photons

  6. Measuring mass 1686

  7. 1905 Relation between energy (E) momentum (p) and mass (m)

  8. Photons have zero mass Energy-momentum of photons is related to their wavelength

  9. Total Energy and momentum are conserved when particles are destroyed and other particles are created in their place.

  10. Mass of initial particle can be determined by measuring the energies and momenta of the final particles.

  11. Large Hadron Collider at CERN

  12. LHC tunnel

  13. CMS detector

  14. Cost: Rs 50,000 crores

  15. Mass of initial particle can be determined by measuring the energies and momenta of the final particles.

  16. CERN seminar 4th July 2012

  17. Particle physics has an accepted definition for a discovery: a "five-sigma" (or five standard-deviation) level of certainty The number of sigmas measures how unlikely it is to get a certain experimental result as a matter of chance rather than due to a real effect Similarly, tossing a coin and getting a number of heads in a row may just be chance, rather than a sign of a "loaded" coin A "three-sigma" level represents about the same likelihood as tossing eight heads in a row Five sigma, on the other hand, would correspond to tossing more than 20 in a row Independent confirmation by other experiments turns five-sigma findings into accepted discoveries

  18. Weak Interactions

  19. Weak interactions are slow and short ranged Weak interactions gauge bosons W, Z are massive

  20. Spontaneous symmetry breaking Magnetic dipoles Less symmetrical state has lower energy

  21. Energy density of Higgs field Spontaneous symmetry breaking

  22. Photon mass in a plasma Anderson, P W (1963). Plasmons, gauge invariance and mass.

  23. Elementary particles I-cards have been changed Name: electron Spin : ½ Charge: - 1 Higgs charge: 0.000003

  24. One new I-card has been issued Name: Higgs Spin : 0 Charge: 0 Higgs charge: 0.13

  25. Thank You
