The electron has two heavier cousins, called the muon and the tau. Muons can be created when high-energy cosmic rays from outer spacehit the top of Earth's atmosphere, generating a shower of exotic particles. Taus are even rarer and harder to produce, as they are more than 3,400 times...
of neutrinos. These are electron neutrinos, muon neutrinos, and tau neutrinos. They are neutrally charged particles that make up half of the total number of leptons, a classification of particles. The other three leptons are negatively charged and are called electrons, muons, and tau particles....
Neutrinos are the neutrally-charged counterpart of electrons, muons, and tau particles. These particles, whether negatively charged or neutrally charged, are considered elementary particles, meaning that they are not made of smaller units of matter and do not bond together to form other particles....
Sterile neutrinos would upend all of known physics because they don't fit into what's known as the Standard Model, a framework that explains almost all known particles and forces except gravity. If MiniBooNE's new results hold up, "That would be huge; that's beyond the Standard Model; th...
Scientists named the three types of neutrinos they have discovered so far for the other matter particles they interact with: the electron neutrino, muon neutrino, and tau neutrino. Neutrinos change between types as they travel, something scientists callneutrino oscillation. ...
Half-integer spin particles have spin values that are half-integers, so 1/2, 3/2, etc. The bosons have whole integer spin values, eg 1, 2, 3 etc. Leptons include electrons, muons, tau particles and their associated neutrinos. Quarks are tiny particles that, when joined together, form ...
A minimal extension to this model can naturally give rise to a CP-even Higgs boson around 126 GeV mass, along with a rich spectrum of new scalar particles and mirror fermions. The objective of the present research is to determine the implications of this model in the light of the 126 GeV...
In addition to six quarks in the Standard Model, we have six leptons. The electron, muon and tau particles plus their neutrinos; the electron neutrino, muon neutrino and tau neutrino. Add to this the four bosons:photon(electromagnetic force),W and Z bosons(weak force) and gluons (strong fo...
which are indivisible.A proton contains two “up” quarks and one “down” quark.A neutron contains two down quarks and one up.The nucleus is held togetherby the strong force, another fundamental force of the Standard Model.Just as photons carrythe electromagnetic force,particles called gluons...
particles called gluons carry the strong force. Electrons, together with up and down quarks, seem to be all we need to build atoms and therefore describe normal matter. However, high energy experiments reveal that there are actually six quarks– ...
