This letter names a function in quantum field theory that relates the coupling parameter to the energyscale.
This letter names a function in quantum field theory that relates the coupling parameter to the energyscale. One quantity denoted by this letter is equal to one over Boltzmann's constant times temperature; thatquantity appears in the exponential of Boltzmann factors. This letter is also used to symbolize the ratio ofan object's speed to the speed of light. In one process named for this letter, a down quark changes to an upquark, releasing an electron and an electron antineutrino. That process, which is mediated by the weakforce, keeps a nucleus' mass number constant but changes the number of protons. For 10 points, identifythis Greek letter which names a form of decay in which a positron or electron is emitted.
