The Social Life Of Quarks
Among particle physicists, Sheldon Stone has a reputation for high standards and brutal honesty. He’s been known to challenge a tenuous claim by shouting in the middle of a colleague’s talk. So when S...
'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...

Bosonic field
In quantum field theory, a bosonic field is a quantum field whose quanta are bosons; that is, they obey Bose–Einstein statistics. Bosonic fields obey canonical commutation relations, as distinct from ...

Pseudovector meson
In high energy physics, a pseudovector meson or axial vector meson is a meson with total spin 1 and even parity (usually noted as J = 1). Compare to a vector meson, which has a total sp...
Strange quark
The strange quark or s quark (from its symbol, s) is the third-lightest of all quarks, a type of elementary particle. Strange quarks are found in subatomic particles called hadrons. Example of hadrons...
Electric charge
Electric charge is the physical property of matter that causes it to experience a force when placed in an electromagnetic field. There are two types of electric charges: positive and negative. Positiv...

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...
Color confinement
Color confinement, often simply called confinement, is the phenomenon that color charged particles (such as quarks) cannot be isolated singularly, and therefore cannot be directly observed. Quarks, by...

Graviphoton
In theoretical physics, a graviphoton (aka gravivector) is a hypothetical particle which emerges as an excitation of the metric tensor (i.e. gravitational field) in spacetime dimensions higher than fo...
Scalar meson
In high energy physics, a scalar meson is a meson with total spin 0 and even parity (usually noted as J=0). Compare to pseudoscalar meson.These mesons are most often observed in proton-antiproton anni...
