Transcript of Higgs Boson

By: Michael Sheffield Higgs Boson Unified Theory Unified Theory Cont. Higgs Field Higgs Boson Higgs Field Cont. Applications Discovery....Sort of The reason for proposing the Higgs boson came out of the discovery that there is an interaction between two of the fundamental forces: the weak force and the electromagnetic force. This interaction implies that electricity, light, magnetism and some forms of radioactivity are all forms of the electroweak force. This theory is called unified theory, which refers to the unification of the electromagnetic and weak forces. This theory is described by multiple equations which all describe correctly the electroweak force and it's force carrying particles. These particles are the proton, and the W and Z bosons. Their is a problem with the way these particles emerge though. The Higgs Field began with the Big Bang. After the universe began to cool the Higgs field grew spontaneously, which meant that anything interacting with the field has mass. Heavier objects that have more mass interact more with the field, while things that have no mass, like the photon, do not interact at all.
Just as all fields do, the Higgs field has a particle, or visible manifestation, associated with it: The Higgs boson. The Higgs boson was initially theorized about in 1964, but due to the importance of such a particle in proving the Higgs field's existence the search for has lasted for more than 40 years. This search has lead to the construction of things like CERN's Large Hadron Collider. The Higgs Boson is said to have no spin, electric charge, or color charge.
Having no spin means that the Higgs boson is the first scalar particle, which is a particle with no spin.
The problem that has arisen in trying to identify the Higgs boson is it's extraordinarily short life span. Upon creation the particle only last 1.56 sextillionths of a second, or 0. 000000000000000000000156 seconds.
This particle is also nearly massless, with a mass of 126 gigaelectron volts (GeV).
Since 1993 most people have known this particle by the name of the "God" particle. This is in reference to the high amount of influence this particle has over the creation of the universe and galaxies. Take the stars for example; their high level of interaction with the Higgs field gives them their mass, which contributes to gravity. If the Higgs boson is proven to be real, the modern physics world would be shaken.
The largest contribution it would bring is that the Standard Model would be proven. The Standard model is currently the most accurate model for explaining the behavior as well as interactions of all particles.
Also, the discovery of the Higgs boson would help to prove the gauge invariant theory, and explain that particles that normally have mass could be manipulated by a force to become massless, instead of having to create totally new massless particles. On July 4th, 2012 scientists at CERN's Large Hadron Collider discovered a particle that behaved very similarly to the Higgs Boson. It had similar properties as well, such as no spin, no electrical or color charge, similar mass, and a similar life expectancy.
The particle was tentatively proven to exist based on this discovery on March 13th, 2013, but the scientists who proved it have not yet found a way to prove the particle found to be a Higgs boson's yet. The problem was that these particles didn't have any mass. This is true of the photon, but both the W and Z bosons have been proven to have mass.
To solve this problem; scientists Peter Higgs, Francois Englert, and Robert Brout proposed the Brout-Englert-Higgs mechanism, which gives the W and Z boson mass, but only when they interact with what we call the Higgs field. After the big bang the Higgs field was at zero. Real World The real world application of discovering this particle has yet to be discovered. However, many of the greatest scientific discoveries haven't found their purpose for decades. Take the statement made by the discoverer of radio waves. He stated that it was just a silly experiment. All we can do is theorize about it's possibilities. Possibilities The solar system could revolve around the earth if we find out how to manipulate the Higgs Field.
This is called geocentrism.
This might cause the destruction of the Earth in the long run though.
It could also help to explain why white dwarf stars have such great gravitational pulls. Questions 1. Where are scientists working to discover the Higgs Boson?
2. What are some defining properties of the Higgs Boson?
3. What two forces does unified theory apply to?
4. What problem is the Higgs Field supposed to fix?
5. What model is the discovery of the Higgs boson going to prove? Bibliography •""God particle": Why the Higgs boson matters - CBS News."
