Acknowledgment……. WE make this slideshow to provide a concrete idea on Higgs Boson theory to all the people of the world. We have worked very hard to make this slideshow, so if you like it then please appreciate our work either by commenting on it or giving us the credit.

PowerPoint Presentation:

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).

PowerPoint Presentation:

The Higgs Boson is a theoretical elementary sub atomic is the only Standard Model (SM) particle that has not yet been observed. Its couplings are proportional to the fermions masses so it couples most strongly to the most massive particles. 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. Composition- elementary particle Mass- 125 billion eV Mean life time- 1.56*10^-22 sec Electric charge- zero(0) Color charge and spin- zero(0) PROPERTIES OF A BOSON

PowerPoint Presentation:

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 5 th 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.

PowerPoint Presentation:

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.
