The ALICE collaboration at the Large Hadron Collider (LHC) has made the first direct observation of the dead-cone effect—a fundamental feature of the theory of the strong force that binds quarks and ...

Particles in the atmosphere affect global climate. For example, the black carbon from burning fossil fuels absorbs and radiates light and heat. To calculate the effects of aerosols on climate, ...

The quantum size effect (QSE) is the change in a material's electronic, optical, magnetic, or thermal behavior when one or more of its dimensions become small enough to confine charge carriers such as ...

A team of theoretical physicists has proposed a new particle existing in a warped fifth dimension that could bridge ordinary matter with dark matter. The model, published in The European Physical ...
