A session given by Prof. Amr Khairat Radi, a team leader in CMS experiment in CERN. The “European Organization for Nuclear Research” or CERN is the largest particle physics laboratory in the world. Its most recent accelerator is the Large Hadron Collider (LHC), a 27 km circular machine that collides beams of protons at the highest energies ever reached in a laboratory. These collisions reach the conditions of the universe of less than a billionth of a second after the Big Bang.
Experiments at the LHC search for new particles and new phenomena that could be present at this early stage of the Universe, while CMS is one of these experiments that are devoted to hunt the Higgs boson.
In this session, Prof. Amr presented the LHC and its experiments, and discussed the most recent results including the discovery of the Higgs boson in 2012. The session started by introducing CERN’s history and its construction purposes after the world war-II. Afterwards, some of the fundamental questions that researchers in CERN are trying to answer were presented, like understanding how does the universe work? What are the basic building blocks of matter? Understanding the origins and evolution of the universe, etc…
Subsequently, the role of different engineering fields in constructing such experiments was addressed. Moreover, other applications of the technologies developed at CERN, such as those being used in other research and medical areas, were mentioned.
