We take this opportunity to express our profound gratitude and deep
regards to Director sir, Principal sir, Ms. Swati Basu for her
exemplary guidance, monitoring and constant encouragement.
We are highly indebted to our parents who provided us a helping
hand to our work and persistently guided us. And mainly this
presentation could not have been accomplished without the splendid
support and co-operation of the members of our group.

3. It is an attempt to explore how a proposed idea of god
particle became today’s elementary particle. How it
derives the new model of fundamental physics. Why it
has been leading the conclusion of “Theory of
everything” .
How a simple asking becomes a famous theory and led
the most complex experimental facilities ever in human
history- The Large Hadron Collider (LHC).

4. • The Higgs Boson is a theoretical
elementary sub atomic is the only
Standard Model (SM) particle that has
not yet been observed. PROPERTIES OF A BOSON
 Composition- elementary particle
• Its couplings are proportional to the  Mass- 125 billion eV
fermions masses so it couples most  Mean life time- 1.56*10^-22 sec
strongly to the most massive particles.
 Electric charge- zero(0)
 Color charge and spin- zero(0)
• The elusive Higgs is so central to the
SM and the theory on which the
whole understanding of matter is
based, if the Higgs does not exist (is
not detected), we will not be able to
explain the origin of mass.

5. • It is an elegant model that describes the
fundamental particles and how they interact
via three of the four fundamental forces of
nature—strong nuclear, weak nuclear, and
electromagnetic—gravity is not included.
• The Higgs boson is the last “missing piece”
of the Standard Model and the 5th member of
the boson family (but not a force carrier).
• The Standard Model has successfully
predicted the existence of the top quark, the
W Boson, and the Z Boson. It is strongly
backed by experimental data and has been
never made false predictions.
• The only SM particle predicted but not yet
detected is the Higgs Boson. If the Higgs is
found, the SM will be considered to be
complete.

10. • With a weaker or flatter Higgs
signal, subtraction of background noise is
necessary to determine if a Higgs is being
produced.
• The LHC results show more background
noise due to gluon interactions (addition
of the strong force), W interactions, and
higher energy.
• The Z Higgs process (used in this study)
appears to have a greater signal at the
Tevatron compared to that of the
LHC, especially for lower Higgs masses.
• The appearance of the Higgs would be an
extremely rare event. If it exists, it should
be seen at the LHC once it acquires
enough data.
