INTRODUCTION
LHC IS THE WORLD’S LARGEST & HIGHEST ENERGY PARTICLE ACCELERATOR
SITUATED IN SWISS FRANCE BOARDER NEAR GENEVA
BUILT BY THE EUROPEAN ORGANISATION FOR NUCLEAR RESEARCH(CERN)
TWO BEAMS OF SUBATOMIC PARTICLES CALLED HADRONS TRAVEL IN OPPOSITE DIRECTIONS INSIDE THE CIRCULAR ACCELERATOR
What is the LHC?
With its 27-km circumference, the world's largest and highest-energy particle accelerator.
Particle physicists are using it to collide protons at very high energies(7 trillion electronvolts).
Operates at about – 3000C,& Speeds particles to almost the speed of light.
Involves 4 big experiments.
The Big Questions..
Truthness of Higgs mechanism for generating elementary particle masses via electroweak symmetry breaking.
Are there extra dimensions, as predicted by various models inspired by string theory?
The CP Violation between Matter & Antimatter.
What was the nature of the quark-gluon plasma in the early universe? (Gravity redefined)
Dark Matter exists or not?
The mass of Matter defined in accordance with Higgs Boson particles..
ATLAS-A Toroidal LHC Apparatus
Investigation of Higgs mechanism, which includes collision of protons resulting in production of elementary particles of different masses & giving rise to the differences between the weak force & electromagnetism by giving the W and Z bosons masses while leaving the photon massless.
The asymmetry between the behavior of matter and antimatter, known as CP violation.
