Example of a particle physics gas pedal: LEP
Experimentation in particle physics - Recent results

As mentioned above, the unification of the electromagnetic and weak interactions requires the creation of particles with masses of around 90 GeV/c²: the W ^± and Z ⁰ bosons. In the framework of the electroweak theory, an electron-positron pair can not only annihilate into a photon, via the electromagnetic interaction, but also into a neutral Z ⁰boson via the weak interaction. In particular, if the energy of the pair e⁺e^- is of the order of magnitude of the mass of the Z ⁰, the two modes are of comparable intensity. Thus, by directing an electron and a positron, each with an energy of 45.6 GeV, face to face, their annihilation by head-on collision leads to the creation of Z ⁰ bosons approximately every other time. This is what happens in the largest gas pedal ever built in the world, the LEP (Large Electron Positron...
