The document outlines the Large Hadron Collider (LHC), detailing its objective to test particle physics predictions and recreate Big Bang conditions. It describes the design, including the collider's structure, the role of detectors, and the scientific goals such as exploring mass origin and dark matter. Additionally, it references the Higgs particle, popularly known as the 'God particle,' and provides interesting facts about the project and its scale.

Objective

4. Principle
 Hadron are subatomic
composite particle held together
by strong electromagnetic force
 Collider is a particle
accelerator with two directed
beams, accelerated to a very
high kinetic energies to produce
high energy collisions

5. Design
5
 Collider has four crossing points
 7 detectors positioned , each designed
for different research
 Two particle beams travel at speed of
light to collide
 Tubes kept at ultrahigh vacuum

6. Design (Continued)
 Guided by a strong magnetic field
by electromagnets
 Accelerator is surrounded by liquid
helium, which cool the magnets
 Detectors give 3-D images of sub-
atomic particles
 Traces are closely analysed

Goals of LHC
 Origin of mass?
 Discover evidence for super-symmetry?
 What are dark matter and dark energy?
 Why is there far more ‘Matter’ than ’Anti-matter’ in the universe?
 How quark-gluon give rise to particles that constitute matter of Universe?

8. 8
Then what is GODs particle?
 Physicist Leon Lederman referred Higgs Particle as "Goddamn Particle”
 Was supposed to be the title of Lederman's book
 His publishers changed it to "The God Particle“
 Intrestingly, believed that God created Universe & Universe is made of Higgs particles
 So Higgs Boson or Higgs particles caught attention as “God Particle”

10. Interesting Facts:
 10, 000 Scientists & Engineers working from every continent, except Antarctica,
where are from India only
 175mts underground, on border of France and Switzerland near
 CERN site draws roughly MW of electrical power
 Beams accelerated in more than 99.99 % of the speed
of light

11. Interesting Facts(Continued):
 Total construction cost of about $6.27 billion (INR )
 Each proton travels km, more than 11,000 times a sec
 Generates Terabytes of data
 Generates 14 Tera-electron Volts (TeV)
