"God Particle" Found? will it be a Historic Milestone in science
The mystery involved in the creation of such a vast universe in such an orderly manner has always fascinated millions of minds. To discover the truth a number of scientists have worked hard and prepared a number of theories in support of "how the world came to exist". In the same sequence, scientists have prepared a Standard Model of particle physics. In this model there are a number of particles like protons, electrons, quarks, leptons, gluons, w, z particle and the Higgs boson.
As we know that electric field causes electrons to flow, similarly a field is to exist for the particles to move and interact in the universe and this field is called Higgs field. The idea of the Higgs field requires the acceptance of a related particle: the Higgs boson, which will satisfy the standard model and hence provide the right answer to the question of creation of universe.
If a particle can move through this field with little or no interaction, there will be no drag, and that particle will have little or no mass. Alternatively, if a particle interacts significantly with the Higgs field, it will have a higher mass.
According to the standard model, if the Higgs field didn't exist, the universe would be a very different place, said SLAC's Peskin, who isn't involved in the LHC experiments."It would be very difficult to form atoms," Peskin said. "So our orderly world, where matter is made of atoms, and electrons form chemical bonds—we wouldn't have that if we did not have the Higgs field."In other words: no galaxies, no stars, no planets, no life on Earth.
In layman's terms the Higgs field was famously imagined by physicist David Miller as akin to a room full of political party workers spread evenly throughout a room. An anonymous person who passes through the crowd with ease would be like the interaction between the field and a massless photon. The British prime minister, however, walks around the room flocked by a swarm of admirers and would be more like the interaction for a particle that acquires a finite mass.
Higgs boson has been formally discovered on 4 july,2012. By the ATLAS and CMS team Large Hardon Collider.it's mass is 125.3±.6 GeV/C² ~126 GeV/C². it's mean lifetime is 1 zeptoseconds and it's electric charge, color charge and spin is zero. Hence most of it's properties resemble a lot to the desired Higgs boson particle in the standard model but some scientist still disapprove it by saying it can be some other particle very close to Higgs boson. However in reply to this the two separate teams of scientist who have discovered it say that they will continue to discover it's properties further for more clearer understanding of the particle. The media has often referred to it as "god particle" derived from the book written on this issue by Leon Lederman who gave his book the title "god particle".
Higgs boson is indeed a final puzzle to complete the standard model and give a strong answer to all the theories which have existed and which have stated that they define the reason for the creation of universe. The discovery of this particle is a big step forward in solving this mystery and indeed a "milestone in the field of science".
