This is the presentation about The God Particle. In this ppt you will be able to get the basic information about the Higgs Boson, the experiment carried out in CERN, the result of that experiment and the motive of that experiment. so do have a look!

1. THE GOD PARTICLE:
If the universe is the answer, then what is the question?

3. Introduction -
It is an elementary particle
known as higgs boson or
higgs particle.
It is represented by the
symbol H0
 Its mass is 125.3±0.6 GeV.
 It has 0 electric charge.
 And the experiment was
theorised by R. Brout, F.
Englert, P. Higgs, G. S.
Guralnik, C. R. Hagen, and T.
W. B. Kibble
 This picture shows what happens when two
protons collide after which they decay almost
immediately into two electrons which are
visible as lines.

4. PETER HIGGS:
• The Higgs Boson is named for
Peter Higgs who, along with two
other teams, proposed the
mechanism that suggested such a
particle in 1964 and was only one
to identify some of its theoretical
properties.
• In mainstream media, it is often
referred to as “The God Particle”,
after the title of Leon Lederman’s
book on the topic (1993).

5. OVERVIEW -
 In particle physics, elementary
particles and forces give rise to
the world around us.
 Physicist explain the behaviour
of these particles and how they
interact using the standard model
which is a widely accepted
framework believed to explain
most of the world we see around
us.

6. HIGGS BOSON
MECHANISM-
 Initially when this model was
being developed it seemed that
these models were incomplete as
they forbid elementary particles
from having any mass.
 Then in 1964 three groups of
physicists almost simultaneously
released papers describing how
masses could be given to these
particles, using an approach
known as spontaneous symmetry
breaking.

7. Higgs Field-
 it is one of the several ways
that this mechanism could
arise.
According to this theory a
field exists throughout space
that is responsible for the
Higgs mechanism.

8. This approach allowed particles to acquire
mass, without breaking other parts of
particle. This idea became known as the
Higgs Mechanism.

9. Higgs boson -
 Higgs Boson is the massive
short lived boson associated
with a higgs field.
If the preferred theory is
correct then this massive
boson will exist and can be
detected in experiments and
tested to see whether it is a
Higgs Boson.

10.  If the tests shows that it is Higgs Boson,
then this would prove the Higgs Field exists,
which in turn will confirm how the Higgs
Mechanism takes place.
 At present as of 2012, a particle has been
detected but not yet tested fully to show if it
is a Higgs boson.

11. INSTITUTION OF LHC
EXPERIMENT
 experiment to show whether
the Higgs Boson did or did not
exist began in 1980s.
 In 2008 the large Hadron
Collider (LHC) was inaugurated,
being the most powerful particle
accelerator ever built.

12.  In late 2011 two of the LHC’s experiments
independently began to suggest “hints” of a
Higgs boson detection.
And in 2012 CERN announced evidence of
discovery of a boson with energy level and
other properties consistent with those
expected in a Higgs Boson.

13. What is God Particle
experiment?
THEORY -
• According to the theory, a field exists
that has non zero strength everywhere
– even in empty space, and that
particle acquire mass by interacting
with this so called higgs field.
•If this theory is true, a matching
particle should also exist and be
detectable, providing a crucial test of
the theory.

14. •About the Experiment –
• One of the primary goals of the Large
Hadron Collider at Cern in Geneva,
Switzerland, the most powerful particle
accelator and one of the most complicated
scientific instrument ever built – is to test
the existence of the Higgs Boson and
measure its properties which would allow
physicists to confirm this cornerstone of
modern theory.

15. What are they trying
to do in this
experiment?
 Scientists at the Large Hadron
collider, smashed together
beams of proton – the “hearts of
tom” – at close to the speed of
light.
 which recreated the
conditions that existed a fraction
of a second after the Big Bang.
After the collision they rapidly
decay.
If Higgs Boson is right then a
few Higgs boson should be
created in every trillion
collisions.

16. Result of the
experiment -
 In July 2012, the scientists at
the CERN nuclear research
facility found the Higgs Boson,
the so called ‘God particle’.
 The leaders of the
experiment said that there
were two independent teams
who have observed a particle
similar to Higgs with mass 126
GeV.
 According to the scientists
they have more than “five
sigma” certainty that the
particle they saw was the
Higgs Boson.
