    • Acknowledgment……. 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.
    • It is an attempt to explore how a proposed idea of godparticle became today’s elementary particle. How itderives the new model of fundamental physics. Why ithas been leading the conclusion of “Theory ofeverything” . How a simple asking becomes a famous theory and ledthe most complex experimental facilities ever in humanhistory- The Large Hadron Collider (LHC).
    • • 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.
    • • 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.
    • • 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.
