Assessing the tension between a black hole dominated early universe and leptogenesis (2021)
Journal Article

We perform the first numerical calculation of the interplay between thermal and black hole induced leptogenesis, demonstrating that the right-handed neutrino surplus produced during the evaporation only partially mitigates the entropy dilution suffer...

Confronting SO(10) GUTs with proton decay and gravitational waves (2021)
Journal Article
King, S. F., Pascoli, S., Zhou, Y.-L., & Turner, J. (2021). Confronting SO(10) GUTs with proton decay and gravitational waves. Journal of High Energy Physics, 2021(10), Article 225 (2021). https://doi.org/10.1007/jhep10%282021%29225

Grand Unified Theories (GUT) predict proton decay as well as the formation of cosmic strings which can generate gravitational waves. We determine which non-supersymmetric SO(10) breaking chains provide gauge unification in addition to a gravitational...

Light neutrino masses from gravitational condensation: the Schwinger–Dyson approach (2021)
Journal Article
Barenboim, G., Turner, J., & Zhou, Y.-L. (2021). Light neutrino masses from gravitational condensation: the Schwinger–Dyson approach. The European Physical Journal C, 81(6), Article 511. https://doi.org/10.1140/epjc/s10052-021-09300-8

In this work we demonstrate that non-zero neutrino masses can be generated from gravitational interactions. We solve the Schwinger–Dyson equations to find a non-trivial vacuum thereby determining the neutrino condensate scale and the number of new pa...

Gravitational Waves and Proton Decay: Complementary Windows into Grand Unified Theories (2021)
Journal Article
King, S. F., Pascoli, S., Turner, J., & Zhou, Y.-L. (2021). Gravitational Waves and Proton Decay: Complementary Windows into Grand Unified Theories. Physical Review Letters, 126(2), Article 021802. https://doi.org/10.1103/physrevlett.126.021802

Proton decay is a smoking gun signature of grand unified theories (GUTs). Searches by Super-Kamiokande have resulted in stringent limits on the GUT symmetry-breaking scale. The large-scale multipurpose neutrino experiments DUNE, Hyper-Kamiokande, and... Read More about Gravitational Waves and Proton Decay: Complementary Windows into Grand Unified Theories.
