Dark matter is usually thought of as something "out there." But we will never truly understand it unless we can bring it down to earth

By observing interactions that are forbidden in the Standard Model, physicists can peek at super symmetric and other happenings

Three families of the fundamental particles called quarks and leptons are known. Recent experiments hint that there is one more family, but there are probably no more than five

In theory these massive elementary particles are required to serve as the carriers of the weak nuclear force. They should be detected soon in the aftermath of collisions between protons and antiprotons

At least one particle that fits none of the established families has emerged from experiments with high-energy neutrinos. The new particle must exhibit some hitherto unobserved property of matter

The recent experimental discovery of a hitherto unobserved class of elementary-particle interactions supports the view that a deep link exists between the weak force and the electromagnetic force

Most of what physicists know about the properties of the fundamental particles of matter is inferred from experiments in which two such particles are made to collide and the scattered products are studied
