We are “fairly sure” that there is a lot of stuff in the Universe which we don’t know about
- School Talk, 2001
Now things have got much clearer: we are now much more certain that we know absolutely nothing about
most of the Universe- School Talk, 2003

Mechanism of explaining the mass of matter still awaits a
crucial verification: discovery of the “HIGGS” particle
There are many possible
explanations of “dark matter” based upon
undiscovered particles
![Page 11: UK Agency for the support of: High Energy Physics - the nature of matter and mass Particle Astrophysics - laws from natural phenomena Astronomy - the](https://reader035.vdocuments.mx/reader035/viewer/2022081518/5515c35d550346486b8b64cd/html5/thumbnails/11.jpg)
3. annihilate to produce energy
1. Take matter and anti-matter
?
? HIGGS
Super Symmetric Particles
2. Accelerate and collide
4. new particles are made from the energy

CERN Large Hadron Collider
•The world’s most powerful particle accelerator
•Due to turn on in 2007
•Will collide protons at 7 Tera Electon Volts….

4 LHC Experiments
ALICE- heavy ion collisions, to create quark-gluon plasmas
- 50,000 particles in each collision
LHCb- to study the differences between matter and antimatter
- producing over 100 million b and b-bar mesons each year
ATLAS- general purpose: origin of mass, supersymmetry, micro-black holes
- 2,000 scientists from 34 countries
CMS- general purpose detector
- muon tracking, electromagnetic calorimeter, central tracking and hadron calorimeter

The LHC Data Challenge
Typical Selectivity: 1 in 1011
Like looking for 1 person in a ten world populations
Or for a needle in 200,000 haystacks!
