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...

Iodine Molecular Movie
This movie, derived from LCLS data, shows an iodine molecule moving in the first 2 trillionths of a second after being excited by a laser pulse. The clouds o...
NASA Mystery: Electron 'Superhighway' Traveling at Speed of Light Discovered Just Outside Earth's Magnetic Field
"This is a puzzling case because we're seeing energetic electrons where we don't think they should be, and no model fits them," said David Sibeck, co-author and THEMIS project scientist at NASA Goddar...
The Higgs-shaped elephant in the room
Higgs bosons should mass-produce bottom quarks. So why is it so hard to see it happening?
Is Particle Physics About to Crack Wide Open?
Hints of an unexpected new particle could be confirmed within days—and if it is, the Standard Model could be going down
What do Albert Camus and string theory have in common?
Physics is really a branch of existential philosophy, says Brian Greene.
How Axions May Explain Time’s Arrow
The irreversibility of time may be a clue as to what makes up the universe’s dark matter.
Neutral Result Charges Up Antimatter Research
Scientists of the international ALPHA Collaboration have once again pushed the boundaries of antimatter research with their latest breakthrough studying the properties of antihydrogen. Published today...
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...
Physicists Offer Theories To Explain Mysterious Collision At Large Hadron Collider
Physicists around the world were puzzled recently when an unusual bump appeared in the signal of the Large Hadron Collider, the world’s largest and most powerful particle accelerator, causing them to ...
'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...
Timeline of particle discoveries
This is a timeline of subatomic particle discoveries, including all particles thus far discovered which appear to be elementary (that is, indivisible) given the best available evidence. It also inclu...
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...
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...

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...
Quasiparticle
In physics, quasiparticles and collective excitations (which are closely related) are emergent phenomena that occur when a microscopically complicated system such as a solid behaves as if it contained...
Atom
An atom is the smallest unit of matter that defines the chemical elements. Every solid, liquid, gas, and plasma is made up of neutral or ionized atoms. Atoms are very small: the size of atoms is measu...

Exotic atom
An exotic atom is an otherwise normal atom in which one or more sub-atomic particles have been replaced by other particles of the same charge. For example, electrons may be replaced by other negativel...
Molecule
A molecule /ˈmɒlɪkjuːl/ is an electrically neutral group of two or more atoms held together by chemical bonds. Molecules are distinguished from ions by their lack of electrical charge. However, in qua...
