An introduction toParticle accelerators

TheLarge Hadron Collidor

What willit address?

1. Demonstrate or rule out the existence of the Higgs Boson

2. Demonstrate or rule out the existence of superpartners

3. The probable existence of higher dimensions

4. Demonstrate the nature of Dark Matter

5. Help explain whether electromagnetism, gravity and strongand weak nuclear forces are manifestations of a single force

6. Explain why gravity is weaker than other forces by severalorders of magnitude

7. The occurrence of a black hole during the moment ofcreation, the big bang

Recreatethe moments

Where is the Higgs boson?

“The LHC could provide evidence for morethan three dimensions of space.”

- Brian Greene * * *

“They will find the Higgs particle…they mightobserve some of the particles that make up themysterious dark matter.”

- Nima Arkani-Hamed* * *

“A Higgs boson will be found (95% probability),and (with 60% probability) supersymmetry.”

- Sir Chris Llewellyn-Smith

“The published result is a long wayfrom evidence or the Higgs boson,

or proof of the existence ofSupersymmetry, or hidden dimensions.

It is a measurement of a quantityknown as pseudorapidity –

‘basically a posh way ofcounting charged particles’”

- David Evans, University of Birmingham
