India at The Large Hadron Collider A Backgrounder The accepted view today is that the Universe started with a gigantic explosion called the Big Bang. For fractions of a second after the Big Bang, the Universe consisted of the most elementary constituents of matter interacting with each other through other particles which are carriers of different kinds of forces existing in nature. And, the carriers of all forces in Nature are bosons, named after the famous Indian physicist Satyendra Nath Bose. The behaviour of these elementary particles is described today by a mathematical model called the Standard Model. According to Standard Model, all particles acquire mass through their interaction with another particle called the Higgs particle (also popularly called the God Particle in the Media), named after the British physicist Peter Higgs. The Higgs particle is again a boson. It is a matter of pride for us that bosons play such an important part in the evolution of Universe and, perhaps, also in the ultimate fate of the Universe. Physical situations similar to what existed at fractions of a second after the Big Bang are experimentally created in laboratories through collision of particles or nuclei. That is the primary intellectual reason why high energy particle accelerators are built. The Standard Model has been tested with considerable precision in accelerator experiments so far and has come out with flying colours. The only missing link has been the Higgs Boson. Unfortunately, the Standard Model does not predict the mass of the Higgs Boson. As the Model continued to have excellent agreement with experimental observations, the anxiety to find the Higgs Boson also kept growing, especially because it plays such an important role in the structure of the Standard Model. All accelerators in the past continued with their search and put bounds on its possible mass......................... ...................... pib.nic.in/newsite/erelease.aspx?relid=86975
