The incessant search for the Higgs boson

If found what to expect of it?

The news that China will build the largest particle accelerator in the world caught the attention of physicists and cosmologists.
In Brazil the first news was published in China News on October 29, 2015 and on the same day replicated in other specialized media.
"China will build between 2020 and 2025 the largest particle accelerator in the world, which will allow scientists to better understand the workings of the universe.
"The design will be completed before 2016," told Wang Yifang, director of the Institute of Physics and High Energy, under the Chinese Academy of Sciences to China Daily.
If the Chinese project succeed, it will be at least twice bigger than the Large Hadron Collider (LHC) of the European Laboratory for Physics Particle (CERN), located on the border between France and Switzerland.
In 2012, the LHC confirmed the existence of the so-called Higgs boson, the elementary particle considered key in the fundamental structure of matter.
According to Wang Yifang, "the LHC generates Higgs bosons along with many other particles, but in the future the Chinese collider will create an extremely pure environment that only produce Higgs bosons".
The new facility will generate up to seven times more energy than the CERN, which has just almost double its power. "

Why this whole frenzy to find and describe this possible particle?

Who is the indicted:
The Higgs boson is a subatomic particle theoretically predicted for almost 50 years: In 1964, Peter Higgs proposed the existence of a field with which the particles interact. This interaction is what would give mass to particles. Those that do not interact with the Higgs field does not have mass and are doomed to travel forever at the speed of light, like photons, the basic unit of light. The basic unit of this field is named after the physicist: The Higgs boson.
It was born at the creation and acceptance of the Standard Model of particle physics, which is not actually a model, but a theory.
Although the best we have today in the opinion of many physicists about the nature of matter, remember that you can re-read my thoughts on theories https://drive.google.com/file/d/0B6dCRlYUXKaKbWtSZTNuVW1KOGM/view?usp=sharing.
After decades of searching, physicists still have not achieved any conclusive evidence that it exists. It is important because its existence would prove that there is an invisible field that permeates the universe, a field that do not react with fermions, and reacting to bosons explain its mass; theoretically, therefore, without the Higgs field or something alike nothing that we know would exist. So this mini particle was also named as "God’s particle" ... What a presumption!
You will remember that the Standard Model theory is actually an "Almost Standard Model" since it does not include the last weak force, Gravity. IF the Higgs boson is found, the Almost Standard Model will be much strengthened and supplemented, perhaps opening new doors for the search the "Theory of Everything."
Somewhere I read that "this does not solve the cure for AIDS or cancer, but it is an effort to better understand the world."

Nonsence! Pure science is not intended directly to practical purposes, but without it there would not exist Applied Sciences.
