Fine Arts

Harnik et al. argue against the anthropic principle by proposing a universe that lacks this. One instance of this interaction is modeled with a unitary matrix that includes three mixing angles and a complex phase that models CP violation. A vector minus axial Lagrangian for this force leads to maximal parity violation, making this force only affect left-handed particles. This force is responsible for quark flavor changing, was unified with electromagnetism by Glashow, Weinberg, and Salaam, and is transmitted by the massive W and Z bosons. For 10 points, name this fundamental force involved in radioactive decays.
