and Large-Hadron-Collider(LHC)
• Started as research associate professor @
the NBI Particle Physics group (HEP) this
year

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

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
