God particle:the origin of mass

　　The Nobel prize in physics of this year is for the discovery of Higgs boson(希格斯玻色子).There were a long history and stories about the “God particle”(上帝粒子).

　　We are all composed of particles.But why particles have mass? This is a big problem among physics community in early 1960s. Higgs particle(accurately, Higgs field) is the solution! In simple, there are a lot of Higgs particles filled up the space. Once we move, Higgs particle will collide with you. You wil feel a “resistance” and their potential energy will be absorbed by you. Therefore, you have mass!

potential energy of Higgs boson

　　Last year, on July 4,LHC(大型強子對撞機)told everyone that they have found a new particle. This year, on March 14,CERN(歐洲核子研究組織)issued a release that the previously detected new particles are Higgs boson.

  

Higgs

　　There are over six people have contributions on Higgs boson,but only Englert and Higgs got 2013 Nobel prize. This is because they are two of the first three people(one died in 2011) to publish their papers(1964 published).

　

Englert

　　The explanations and stories above are oversimplifications. So if there are some concepts seems confused and you want to know the details,you can ask me in private.

　　

　　If you want to know more by yourselves,here are some key words that you can google:boson(玻色子),spontaneous　symmetry breaking(自發對稱破缺), Nambu-Goldstone theorem(南部-戈德斯通定理),electroweak unified theory(電弱統一理論),standard model(標準模型)

I recommend this book!

This article is great! But may be a little difficult to you.http://case.ntu.edu.tw/blog/?p=14336
