By comparing the new ultraprecise measurement and the prediction, scientists gave the theory one of its strictest tests yet. The new measurement agrees with the standard model’s prediction to ...

Typically, when looking at a particle in a box (infinite well) this is the starting equation. Now for the infinite well. Inside the well, V=0 and there is no solution outside the well (because the ...

NPR's Ayesha Rascoe speaks to Esra Barlas Yücel, a researcher at University of Illinois at Urbana-Champaign, about Fermilab's most precise measurements of the muon particle's magnetic wobble.

But recent results hinting at unexplained new physics beyond the standard model are of this second type. Detailed studies from the LHCb experiment found that a particle known as a beauty quark ...

Matter particles come in two main varieties, leptons and quarks. (Note that, for every kind of matter particle in nature, there is also an antimatter particle, which has the same mass but is opposite ...

Excitement swirled in the physics community when, in 2012, physicists discovered the Higgs boson, an elementary particle predicted by the Standard Model that relates to how objects have mass. But ...

According to the Standard Model, W bosons (together with another particle, called Z bosons) are responsible for the weak nuclear force, one of the four forces that hold together all observable ...
