![]() There is suspicion that since the Higgs boson is sensitive to the different quark and lepton masses, it may somehow play a role in how masses are assigned. Since the top quark is ~40 times more massive than the bottom quark, it will interact with Higgs boson 40 times more strongly. We now know that quarks and leptons interact with the Higgs boson proportionally to their masses. However, thanks to the 2012 discovery of the Higgs boson, there is a new avenue that may shed light upon the mass hierarchy problem. ![]() Of course there are new models and hypotheses that offer explanations, but none have been verified by data. On the contrary, the model works very, very well it is simply incomplete. This does not mean that the Standard Model is “wrong”. This is called the “ Mass Hierarchy Problem” of the Standard Model and stems from the fact that the quark and lepton masses in the theory are not predicted but are taken as input parameters. Presently, no one has any idea why the top quark is so much heavier than the bottom quark, or why both are orders of magnitude heavier than the electron and muon. The top quark tells us much about the Standard Model of particle physics, but it also may be a window to new physics. The W boson can subsequently decay into a charged lepton and a neutrino or into a quark and anti-quark. Top quark decaying into real, on-shell W boson and bottom quark. Physicists have to infer their properties from the physics of bound states…. However, the process hadronization means that we only observe the bound states of colored objects and not the colored objects themselves. These new colored particles will then form bound states with the old colored states. Hadronization is when two colored objects are far away from one another and the strong nuclear attraction between the two becomes so strong that a pair of colored objects will spontaneously be produced in the space between them. When colored objects (quarks and gluons) are produced at collider and fixed target experiments, they undergo a process called hadronization. The top quark is also colored, meaning that is interacts with gluons and is influenced by the strong nuclear force (QCD). It has an intrinsic angular momentum (spin) equal to the proton’s or electron’s spin. ![]() It has an electric charge that is 2/3 as large as the proton. ![]()
