'Material Universe' Yields Surprising New Particle
An international team of researchers has predicted the existence of a new type of particle called the type-II Weyl fermion in metallic materials. When subjected to a magnetic field, the materials cont...
Tiny Drops Of Early Universe 'Perfect' Fluid
First results from collisions of three-particle ions with gold nuclei reveal clear-cut evidence of primordial soup's signature particle flow. The Relativistic Heavy Ion Collider (RHIC), a particle col...
Evidence Suggests Subatomic Particles Could Defy The Standard Model
A team of physicists working at CERN's Large Hadron Collider (LHC) has found new hints of particles -- leptons, to be more precise -- being treated in strange ways not predicted by the Standard Model....
After A Half Century, The Exotic Pentaquark Particle Is Found
In July, scientists at the Large Hadron Collider (LHC) reported the discovery of the pentaquark, a long-sought particle first predicted to exist in the 1960s as a consequence of the theory of elementa...
Researchers Build New Fermion Microscope
Fermions are the building blocks of matter, interacting in a multitude of permutations to give rise to the elements of the periodic table. Without fermions, the physical world would not exist. Example...
Newly discovered particle is both matter and antimatter at the same time
You probably think of matter and antimatter as mortal enemies, since their equivalent particles (such as protons and antiprotons) normally destroy each other on contact. However, there are now hints t...

Quark
Matter is all the stuff that we see, feel, and smell around us. By definition, matter has mass and takes up space. Matter includes substances such as water, ...
Elementary particle
In particle physics, an elementary particle or fundamental particle is a particle whose substructure is unknown, thus it is unknown whether it is composed of other particles. Known elementary particl...
Fermion
In particle physics, a fermion (a name coined by Paul Dirac from the surname of Enrico Fermi) is any particle characterized by Fermi–Dirac statistics. These particles obey the Pauli exclusion principl...
Quark
A quark (/ˈkwɔrk/ or /ˈkwɑrk/) is an elementary particle and a fundamental constituent of matter. Quarks combine to form composite particles called hadrons, the most stable of which are protons and ne...

Lepton
A lepton is an elementary, half-integer spin (spin ⁄2) particle that does not undergo strong interactions, but is subject to the Pauli exclusion principle. The best known of all leptons is the e...
Boson
In quantum mechanics, a boson (/ˈboʊsɒn/, /ˈboʊzɒn/) is a particle that follows Bose–Einstein statistics. Bosons make up one of the two classes of particles, the other being fermions. The name boson w...
Hadron
In particle physics, a hadron /ˈhædrɒn/ (Greek: ἁδρός, hadrós, "stout, thick") is a composite particle made of quarks held together by the strong force (in a similar way as molecules are held toge...
Tauon
The tau (τ), also called the tau lepton, tau particle or tauon, is an elementary particle similar to the electron, with negative electric charge and a spin of ⁄2. Together with the electron, the...

Topness
Topness (also called truth), a flavour quantum number, represents the difference between the number of top quarks (t) and number of top antiquarks (t) that are present in a particle:By convention, top...
Majorana fermion
A Majorana fermion (/maɪəˈrɒnə ˈfɛərmiːɒn/), also referred to as a Majorana particle, is a fermion that is its own antiparticle. They were hypothesized by Ettore Majorana in 1937. The term is sometime...
Majoron
In particle physics, majorons (named after Ettore Majorana) are a hypothetical type of Goldstone boson that are theorized to mediate the neutrino mass violation of lepton number or B − L in certain hi...
Constituent quark
A constituent quark is a current quark with a covering.In the low energy limit of QCD, a description by means of perturbation theory is not possible. Here, no Asymptotic freedom exists, but the intera...
Dirac fermion
In physics, a Dirac fermion is a fermion which is not its own antiparticle. It is named for Paul Dirac. They can be modelled with the Dirac equation.The alternative to a Dirac fermion is a Majorana ...
Chameleon particle
The chameleon is a hypothetical scalar particle that couples to matter, postulated as a dark energy candidate. Due to a non-linear self-interaction, it has a variable effective mass which is an increa...
Pentaquark
A pentaquark is a hypothetical subatomic particle consisting of four quarks and one antiquark bound together (compared to three quarks in normal baryons). As quarks have a baryon number of +⁄3, ...
Exotic baryon
Exotic baryons are hypothetical composite particles that are bound states of 4 or more quarks and additional elementary particles. This is to be contrasted with ordinary baryons, which are bound state...

B meson
In particle physics, B mesons are mesons composed of a bottom antiquark and either an up (B+), down (B0), strange (B0s) or charm quark (B+c). The combination of a bottom antiquark and a top quark is n...
Kadowaki-Woods ratio
The Kadowaki–Woods ratio is the ratio of A, the quadratic term of the resistivity and γ, the linear term of the specific heat. This ratio is found to be a constant for transition metals, and for heavy...
Chargino
In particle physics, the chargino is a hypothetical particle which refers to the mass eigenstates of a charged superpartner, i.e. any new electrically charged fermion (with spin 1/2) predicted by supe...
