Description

Scalar leptoquarks are scalar bosons that couple simultaneously to a quark and a lepton. They commonly appear in the Higgs sectors of grand unified theories. Stringent experimental limits on proton decay imply that these particles are superheavy. Graviton bremsstrahlung from the decays of such superheavy leptoquarks, arising from quantum gravitational processes, offers a promising source of a potentially detectable stochastic gravitational wave background. We compute the evolution of the number density of scalar leptoquarks in the early universe and assess the detection prospects for their gravitational wave signals at future observatories.
