Let’s Begin......
IF GOD EXITS...
THEN WHY NOT GOD PARTICLE!!
THE GOD PARTICLE“CHALLENGE OF PARTICLE PHYSICS”
“GOD-PARTICLE” KNOWN AS
“HIGGS BOSON”
Let’s HIGGS BOSONIn the Standard Model, the
Higgs particle is a boson, a type of particle that allows multiple identical particles to exist in the same place in the same quantum state.
It has no spin, electric charge.
Is part of a Higgs mechanism that gives mass to everything .
Is the last missing piece of the Standard Model for particle physics
The Higgs particle creates a Higgs field* that permeates space time.
*Higgs field: Has the unusual property of a non-zero amplitude in its ground state; i.e. a non-zero vacuum expectation value.

Guyzz…Who iz Higgs?
Yes, this is Peter Higgs and he did propose the existence of the Higgs boson(at CERN). “ D fatty one!! ”
The men behind gauge symmetry breaking
Peter Higgs
Francois EnglertRobert Brout
The Higgs particle is named after the British theorist Peter Higgs who along with Robert Brout and François Englert theorized its existence in 1964.
HISTORY
The Higgs boson is often referred to as the "God particle" by individuals outside the scientific community, from the title of a book on the Higgs boson and particle physics by Nobel Physics prize winner Leon Lederman.
WHY IS “HIGGS” .. SO IMPORTANT ???The Higgs is part of many theoretical equations
underpinning scientists' understanding of how the world came into being.
It opens the possibility to potential new discoveries including a theory known as "super-symmetry"
How certain particles acquire mass.
IF UNIVERSE IS ANSWER, “HIGGS BOSON” WAS THE QUESTION!!!!
PRODUCTION OF HIGGS BOSON A Higgs particle can be produced
much like other particles that are studied, in a particle collider.
This involves accelerating a large number of particles to extremely high energies and extremely close to the speed of light, then allowing them to smash together.
Protons and lead ions (the bare nuclei of lead atoms) are used at the LHC(LARGE HADRON COLLIDER)
The most common expected processes for Higgs boson production are:
Gluon fusion
Higgs Strahlung
Top fusionVector boson fusion
BASIC PARTS OF LHC
Basic details about LHCThe Large Hadron Collider at CERN in Switzerland, Built in a 27 km tunnel under the ground near Geneva
It was designed to collide two beams of protons, initially at energies of 3.5 TeV per beam (7 TeV total),

CAUTION
“JUST NEXT 3 SLIDES “
WATCH IT CAREFULLY!!
Roomful of people = scattered particles with mass
Or The higgs field
Famous person entering room = massive particleRush in closer to be near her
Swarm of people = group of particles = massAs d guests passes..surrounding guest gives him to momentum
SO What’s the need of Higgs?
Fundamental symmetries of nature require that all the elementary particles and force carriers are massless
in an “ideal” world all elementary particles would be massless
but in the real world the elementary particles have widely differing masses
so the symmetry must be broken
This is what the Higgs mechanism and electroweak symmetry breaking is all about
What is symmetry breaking?
Consider a smooth ball at the top of a very smooth symmetric hill
The ball can roll in either direction
… there is a left-right symmetry
But the ball can only fall in one direction
… the symmetry is broken
• CERN's atom smasher, the Large Hadron Collider, alone cost some $10 billion to build and run.
• This includes the salaries of thousands of scientists and support staff around the world who collaborated on the two experiments that independently pursued the Higgs.
HOW MUCH DID IT COST?
APPLICATION:
Learning how certain particles acquire mass.Insight into cosmic inflation.Insight into energy of vacuum.Learning how symmetric breaks into within weak electroweak interaction. link into ‘cosmological interest’ problem.
Geneva, 4 July 2012. At a seminar held at CERN1 today as a curtain raiser to the year’s major particle physics conference
DISCOVERY OF GOD PARTICLES WILL SOLVE MANY UNSOLVED MYSTERIES OF PHYSICS………………….!!!!!
WHAT'S NEXT?
• Scientists will keep probing the new particle until they fully understand how it works.
•They hope to understand the 96 percent of the universe that remains hidden from view.
• This may result in the discovery of new particles and even hitherto unknown forces of nature.
THANK U!!
