Particle physics

kaons

Physics; Particle physics

See K-Meson.

lepton

Physics; Particle physics

Along with quarks, leptons make up all known matter. Unlike quarks, leptons do not participate in strong interactions. Neutrinos and electrons are two common examples. There are three flavors of ...

lepton flavor violation

Physics; Particle physics

In the Standard Model, leptons do not change flavor. For example, a muon would never turn into an electron. If this were observed, it would be a signal for new physics. Evidence for Neutrino ...

linear collider

Physics; Particle physics

An accelerator that accelerates two beams of charged particles in a straight line, and then collides them head on.

luminosity

Physics; Particle physics

This figure of merit for an accelerator quantifies the intensity of the beams. It is directly related to the number of events produced at the machine.

meson

Physics; Particle physics

A hadron composed of a quark and an anti-quark.

mixing angles

Physics; Particle physics

A particle of a given flavor sometimes transforms into a similar particle of a different flavor. The parameters that quantify how likely this is to occur are known as mixing angles.
