Majorana Fermion Discovered

That is too bizarre for me to get my head around. Its own anti-particle?

How long is the half-life? About 10^-3 femtoseconds or less?

And where does it fit in the standard model?

Probably somewhere off the page, or on the back of the page, I suspect.

It's in the Fermions...just pencil it in for now....

..."The Standard Model includes 12 elementary particles of spin  ¹⁄₂ known as fermions. According to the spin-statistics theorem, fermions respect the Pauli exclusion principle. Each fermion has a corresponding antiparticle.

The fermions of the Standard Model are classified according to how they interact (or equivalently, by what charges they carry). There are six quarks (up, down, charm, strange, top, bottom), and six leptons (electron, electron neutrino, muon, muon neutrino, tau, tau neutrino). Pairs from each classification are grouped together to form a generation, with corresponding particles exhibiting similar physical behavior (see table).

The defining property of the quarks is that they carry color charge, and hence, interact via the strong interaction. A phenomenon called color confinement results in quarks being very strongly bound to one another, forming color-neutral composite particles (hadrons) containing either a quark and an antiquark (mesons) or three quarks (baryons). The familiar proton and neutron are the two baryons having the smallest mass. Quarks also carry electric charge and weak isospin. Hence, they interact with other fermions both electromagnetically and via the weak interaction.

The remaining six fermions do not carry colour charge and are called leptons. The three neutrinos do not carry electric charge either, so their motion is directly influenced only by the weak nuclear force, which makes them notoriously difficult to detect. However, by virtue of carrying an electric charge, the electron, muon, and tau all interact electromagnetically.

Each member of a generation has greater mass than the corresponding particles of lower generations. The first generation charged particles do not decay; hence all ordinary (baryonic) matter is made of such particles. Specifically, all atoms consist of electrons orbiting around atomic nuclei, ultimately constituted of up and down quarks. Second and third generation charged particles, on the other hand, decay with very short half lives, and are observed only in very high-energy environments. Neutrinos of all generations also do not decay, and pervade the universe, but rarely interact with baryonic matter."...

Maybe throw it in with the new set proposed to be added:

but

The team has named their new model SMASH for "Standard Model Axion See-saw Higgs portal inflation." The proposed particles are rho (to help explain inflation), the axion (to help explain dark matter) a color triplet fermion and three heavy right-handed neutrinos.

It is still far too early to predict whether the model will be accepted by the physics community, but one thing it has in its favor is that the predictions it makes are clear, which means they can be tested and either proved or disproved. It should be noted that the theory does not include such things as the hierarchy problem or deal with the cosmological constant.

If it's its own antiparticle, does that mean if two come together they will explode?

It means it self-destructs.

Annihilates...

It does not even get to say "exterminate" in an over-excited tone.

You spelled marijuana wrong and I think it was discovered along time ago...

When you ferment it, you get marijuana wine. Where's the big discovery??

The drink is bhang, and had some reference on "Bones" (I can't remember if Bones or Angela had tried it before when they were traveling India).
