Although the photon is indeed massless, experiments show that the weak force's bosons have mass.This meant that either gauge invariance was an incorrect approach, or something else – unknown – was giving these particles their mass, but all attempts to suggest a theory able to solve this problem just seemed to create new theoretical issues.
The presence of the field, now confirmed by experimental investigation, explains why some fundamental particles have mass, despite the symmetries controlling their interactions implying that they should be massless.It is also very unstable, decaying into other particles almost immediately.It is a quantum excitation of one of the four components of the Higgs field.The lower event in the ATLAS experiment shows a decay into four muons (red tracks).Unlike other known fields such as the electromagnetic field, it has a non-zero constant value in vacuum.Although Higgs's name has come to be associated with this theory, several researchers between about 19 independently developed different parts of it.
In mainstream media the Higgs boson has often been called the "God particle", from a 1993 book on the topic; In the Standard Model, the Higgs particle is a boson with spin zero, no electric charge and no colour charge.(A separate theory, General Relativity, is used for gravity.) In this model, the fundamental forces in nature arise from properties of our universe called gauge invariance and symmetries.The forces are transmitted by particles known as gauge bosons.When this happens, three components of the Higgs field are "absorbed" by the SU(2) and U(1) gauge bosons (the "Higgs mechanism") to become the longitudinal components of the now-massive W and Z bosons of the weak force.The remaining electrically neutral component either manifests as a Higgs particle, or may couple separately to other particles known as fermions (via Yukawa couplings), causing these to acquire mass as well.USB Connected Logo " data-medium-file=" data-large-file=" class="alignright size-full wp-image-7576" title="USB Connected Logo" src=" alt="USB Connected Logo" width="192" height="234" /For all those who has recently purchased an Android smart phone and would like to know on how you can enable the USB storage right on your Android device then we will help you to do the same which we will see in the due course of this article.
