Gravitational wave signatures of lepton universality violation

We analyze the prospects for using gravitational waves produced in early universe phase transitions as a complementary probe of the flavor anomalies in B meson decays. We focus on the left-right SU(4) model, for which the strength of the observed lepton universality violation and consistency with other experiments impose a vast hierarchy between the symmetry breaking scales. This leads to a multipeaked gravitational wave signature within the reach of upcoming gravitational wave detectors.

Automated summary

Researchers analyzed the potential of using gravitational waves produced in early universe phase transitions as a probe of flavor anomalies in B meson decays, and found a possible multi-peaked gravitational wave signature.
