Introduction to Particle Physics Course overview Jørgen Beck Hansen Autumn 2006 About me • 9 years research fellow and staff at CERN, Switzerland • Worked on Large-Electron-Positron (LEP) and Large-Hadron-Collider(LHC) • Started as research associate professor @ the NBI Particle Physics group (HEP) this year • Office: Blegdamsvej 21 (building M) mc-8 • Email: [email protected] Course synopsis 1. 2. 3. 4. 5. 6. 7. 8. 9. 10. 11. Basic concepts Leptons, quarks and hadrons Experimental methods Space-Time Symmetries Hadrons: quantum numbers and excited states Hadrons: quark states and colour QCD, jets and gluons Weak interactions: W and Z bosons Weak interactions: electroweak unification Weak interactions: charge conjugation and parity Beyond the standard model Crash course: ~200 pages in 7 weeks Practicalities • Litterature: B.R. Martin & G. Shaw, ”Particle Physics”(2nd edition), 1997, publ. John Wiley & Sons Ltd • Strongly recommended to look at the course web-page – Lots of additional information – Points to several GOOD introductionary sites Painless Particle Physics: ParticleAdventure.org • Credits to former teacher: Mogens Dam for slides etc. • Non-trivial timetable since both Jens-Jørgen Gårdhøje and I have to travel during the course Course Schedule (preliminary) Week Monday Thursday 28/8-1/9 14:00-16:00: Particle Physics Chapter 1 + appendix A 9:00-12:15: Particle Physics - Chapter 2 + appendix B, Exercises: Ch 1: 1-3+5 13:00- 16:00: Particle Physics - Chapter 3 + 4 (part) 4/9-8/9 13:00-16:00: Particle Physics Chapter 4 (rest) + 5, Exercises: Ch 2+4 9:00-12:15: Particle Physics - Chapter 6, Exercises: Ch 4+5 13:00- 16:00: Particle Physics - Chapter 7 + 8 (part) 11/9-15/9 14:00-16:00: Nuclear Physics 9:00-11:00: Nuclear Physics 11:15-12:15: Particle Physics - Chapter 8 (rest) 13:00-16:00: Particle Physics - Chapter 9, Exercises: Ch 6+7 18/9-22/9 14:00-16:00: Nuclear Physics 9:00-11:00: Nuclear Physics 11:15-12:15: Particle Physics - Chapter 10 (part) 13:00-16:00: Particle Physics - Chapter 10 (rest), Exercises: Ch 8+9 25/9-29/9 14:00-16:00: Nuclear Physics 9:00-11:00: Nuclear Physics 11:00-13:00: Nuclear Physics 14:00-16:00: Nuclear Physics 2/10-6/10 14:00-16:00: Nuclear Physics 9:00-11:00: Nuclear Physics 11:00-13:00: Nuclear Physics 14:00-16:00: Nuclear Physics 9/10-13/10 14:00-16:00: Nuclear Physics 9:00-11:00: Nuclear Physics 11:15-12:15: Particle Physics - Chapter 11 13:00-16:00: Particle Physics - Review of main topics, Exercises: ch 10 Where to go from here? • This course give you the first peak into the wonderful world of particle physics • Explain you how to “navigate and swim” in the shallow end of the pool • Particle physics ”fag-pakke”: 1. Theory: General reletivity – Poul Olesen 2. Theory: Particle physics – Poul Henrik Damgaard 3. Experiment: Experimental methods – Peter Hansen 4. Experiment: High Pt physics at the frontier -- JBH Teach you to swim in deep unknown waters CERN Summer Student Programme • A unique opportunity to enjoy a summer in Switzerland, learning bleeding-edge science and technology and meeting new friends from all over the world • •Google “CERN Summer Student”, or go directly to http://humanresources.web.cern.ch/HumanReso urces/external/recruitment/Students/students.as p • 2-3 months of training at CERN: work in a research group, lectures, student sessions, visits to experiments, workshops,… Particle Physics in a nutshell? Special relativity + Quantum mechanics • Formalism is 4-vectors (“kinematics”) • Physics content is quantum mechanics • Plus a big bag of new particles and concepts APPLIED special relativity and quantum mechanics The MAGIC key • Natures deepest secret (and we cannot directly see deeper) • Gives us quantum mechanics and string theory • Add the “de Broglie” relation: l = h/p • Re-define units: h=c=1 The intuitive understanding of particle physics and its numerical mechanics
