Updated Running Quark and Lepton Parameters at Various Scales
Stefan Antusch, Kevin Hinze, Shaikh Saad
In the light of the recent Particle Data Group (PDG) release, we revisit the running quark and lepton Yukawa couplings, together with the quark mixing parameters, across a range of…
Metastable Cosmic Strings and Gravitational Waves from Flavour Symmetry Breaking
Stefan Antusch, Kevin Hinze, Shaikh Saad
Metastable cosmic strings (MSCSs) are among the best-fitting explanations of the 2023 pulsar timing array (PTA) signal for gravitational waves at nanohertz frequencies. We propose…
Explaining PTA Results by Metastable Cosmic Strings from SO(10) GUT
Stefan Antusch, Kevin Hinze, Shaikh Saad
In a recent paper (see https://doi.org/10.1103/PhysRevD.108.095053), we have demonstrated that the 2023 PTA results, which hint at a stochastic gravitational wave (GW) background a…
Leptoquark-Mediated Two-Loop Neutrino Mass in Unified Theory
Kevin Hinze, Shaikh Saad
Scalar leptoquarks naturally arise within unified theories, offering a promising avenue for addressing one of the most significant challenges of the Standard Model--the existence o…
Probing SUSY at Gravitational Wave Observatories
Stefan Antusch, Kevin Hinze, Shaikh Saad +1
Under the assumption that the recent pulsar timing array evidence for a stochastic gravitational wave (GW) background at nanohertz frequencies is generated by metastable cosmic str…
