  • Essay / Necessary modifications to the Standard Model after...

    The Standard Model (SM) describes the fundamental particles of matter and their interaction with each other governed by three of the fundamental forces; electromagnetic, strong and weak. The Higgs boson, proposed fifty years ago by theoretical physicists (Brumfiel, 2012), is the fundamental particle responsible for mass and constitutes an essential component of the standard model. Furthermore, it is the only SM particle that has not yet been observed. In 2012, a particle conforming to the Standard Model Higgs boson, with a mass of around 125 GeV (Aad et al. 2012), was observed at the Large Hadron Collider (LHC) with the ATLAS detector, completing the standard model. This discovery of the Higgs boson is of great scientific importance as it completes the Standard Model or encourages physicists to extend the SM and other models. Practical uses, whether directly using the boson itself or using processes and technologies used to discover it, will also be considered. This discovery opens a whole new range of questions and implications for physicists, such as the fact that there could be a "Higgs family" rather than the single Higgs boson predicted in the Standard Model and observed experimentally in 2012. This means that the Standard Model will have to be extended or other theories will have to be considered such as supersymmetry to explain such concepts. In the Standard Model, particles known as bosons are responsible for mediating the force between fundamental particles; quarks and leptons. Before the discovery of the Higgs-like particle using the Large Hadron Collider's ATLAS detector, the Higgs boson was the only Standard Model particle that had not yet been discovered. Various measurements that ...... middle of paper ...... like photons, do not. It also gives a fundamental explanation of why the universe appears the way it does. Without the Higgs, atoms and molecules would not be possible. Currently, there is no practical use for the Higgs boson, because the time it lasts before decaying is far too short to use the particles themselves. However, efforts to discover the Higgs boson contributed to technologies used today, such as the World Wide Web, and to medical advances against cancer. It is suggested that explanations beyond the Standard Model are needed to explain some of the ATLAS observations, such as the mass of light (125 GeV). Observations that require further explanation open the possibility of new research that could lead to the confirmation or decline of theories or perhaps even entirely new concepts not yet predicted..
