Flavour Structure of GUTs and Uncertainties in Proton Lifetime Estimates
Helena Kolešová, Michal Malinský
We study the flavour aspects of proton lifetime estimates in simple Grand unified models paying particular attention to their inherent fragility due to the notorious lack of contro…
Theoretical Uncertainties in Proton Lifetime Estimates
Helena Kolešová, Michal Malinský, Timon Mede
We recapitulate the primary sources of theoretical uncertainties in proton lifetime estimates in renormalizable, four-dimensional and non-supersymmetric grand unifications that rep…
Neutrino-axion-dilaton interconnection
Stefano Bertolini, Luca Di Luzio, Helena Kolešová +2
We show that a recently proposed framework that provides a simple connection between Majorana neutrinos and an invisible axion in minimal scalar extensions of the standard electrow…
Massive neutrinos and invisible axion minimally connected
Stefano Bertolini, Luca Di Luzio, Helena Kolešová +1
We survey a few minimal scalar extensions of the standard electroweak model that provide a simple setup for massive neutrinos in connection with an invisible axion. The presence of…
Minimal SO(10) grand unification at next-to-leading order
Helena Kolešová, Michal Malinský
We comment on the status and prospects of the minimal non-supersymmetric renormalizable SO(10) grand unified model. We emphasize its unique predictive power owing to the particular…
Proton lifetime in the minimal SO(10) GUT and its implications for the LHC
Helena Kolešová, Michal Malinský
We review the current status of the minimal non-supersymmetric SO(10) grand unified theory and perform a detailed next-to-leading-order analysis of the gauge unification and proton…
Witten's loop in the flipped SU(5) unification
Michal Malinský, Carolina Arbeláez Rodríguez, Helena Kolešová
We study a very simple, yet potentially realistic renormalizable flipped SU(5) scenario in which the right-handed neutrino masses are generated at very high energies by means of a…
Witten's mechanism in the flipped SU(5) unification
Carolina Arbeláez, Helena Kolešová, Michal Malinský
We argue that the Witten's loop mechanism for the right-handed Majorana neutrino mass generation identified originally in the SO(10) grand unification context can be successfully a…
