One particle involved in this interaction comprises the so-called neutral currents first observed at CERN in 1973. One theory containing this S U two interaction is subject to symmetry breaking below 100 gigaelectronvolts by the Higgs mechanism. Quark flavors can be changed by interactions with one mediator of this force, which leads to its best-known effect. It is short range due to the very high masses of its carriers, which explains some aspects of beta decay, which it causes. This force carried by the W and Z bosons was unified by Glashow, Salam, and Weinberg with electromagnetism. For 10 points, name this force that is not even nearly as strong as the strong force.
