Direct measurements of the wave nature of matter
New experimental techniques map out wave properties only known previously from theory.
Reality Doesn’t Exist Until We Measure It, Quantum Experiment Confirms
Australian scientists have recreated a famous experiment and confirmed quantum physics's bizarre predictions about the nature of reality, by proving that reality doesn't actually exist until we measur...
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
Step Inside The Large Hadron Collider (360 video)
A 360 tour of CERN that takes you deep inside the Large Hadron Collider – the world’s greatest physics experiment - with BBC Click’s Spencer Kelly.
A Different Picture Of Quantum Surrealism
With its ideas of particles zipping in and out of existence, quantum mechanics is probably the kookiest-sounding theory in science. And our understanding of it is little helped by the mysterious “pro...
Much Like White Light, Spacetime Is Also Composed Of A Certain Rainbow
When white light is passed through a prism, the rainbow on the other side reveals a rich palette of colors. Theorists from the Faculty of Physics, University of Warsaw have shown that in models of th...
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 ...
Artificial intelligence called in to tackle LHC data deluge
The next generation of particle-collider experiments will feature some of the world’s most advanced thinking machines, if links now being forged between particle physicists and artificial intelligence...
The LHC Is Now Colliding Lead at the Highest-Ever Energies
The Large Hadron Collider has been back online and pushing the limits of physics again for a few months now. But it’s about to enter a new phase, colliding lead ions at twice the energy that any colli...
'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...
CERN Collides Heavy Nuclei At New Record High Energy
One of the very first collisions recorded between two lead ions at the LHC's top energy. The energy in the center-of-mass system is approximately 1000 TeV. Todays events bring collisions physics into ...
Antimatter Not So Different After All
Rice University researchers share the first measurements of the attractive force between antiprotons. The discovery gives physicists new ways to look at the forces that bind matter and antimatter. Ant...

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...
Particle physics
Particle physics is a branch of physics which studies the nature of particles that are the constituents of what is usually referred to as matter - particles with mass; and radiation - massless particl...
Wave-particle duality
Wave–particle duality is the concept that every elementary particle or quantic entity exhibits the properties of not only particles, but also waves. It addresses the inability of the classical concep...

Particle technology is that branch of science and engineering dealing with the production, handling, modification, and use of a wide variety of particulate materials, both wet or dry, in sizes ranging...
Scharnhorst effect
The Scharnhorst effect is a hypothetical phenomenon in which light signals travel faster than c between two closely spaced conducting plates. It was predicted by Klaus Scharnhorst of the Humboldt Univ...
Infraparticle
An infraparticle is an electrically charged particle and its surrounding cloud of soft photons—of which there are infinite number, by virtue of the infrared divergence of quantum electrodynamics. That...
