This spinless particle is the force carrier for the (*) electromagnetic force and the annihilation of an electron and positron results in two of these.
This particle results from the gauge symmetry of the complex numbers. In Doppler cooling, this particle is shot from two directions at atoms. The Stark-Einstein law states that one molecule reacts with exactly one of these. In the Mossbauer effect, these bosons cause no recoil in solids. This spinless particle is the force carrier for the (*) electromagnetic force and the annihilation of an electron and positron results in two of these. This massless particle has momentum equal to h-bar times the wave vector and can generate current when they hit certain metals in an effect first found by Hertz. For 10 points, name this particle representing quanta of light.
This particle results from the gauge symmetry of the complex numbers.
