Supermassive charged gravitinos and the Lux-Zeplin event
Krzysztof A. Meissner, Hermann Nicolai
The Lux-Zeplin collaboration recently reported one unusual event which was interpreted as first evidence for a WIMP (arXiv:2609.02823[hep-ex]). In this note we offer an alternative…
Planck mass gravitinos in Einstein-Maxwell backgrounds
Artur Krawczyk, Krzysztof A. Meissner, Hermann Nicolai +1
Charged massive spin-3/2 fields have long been regarded as problematic, because their coupling to electromagnetism generically leads to loss of hyperbolicity, acausal propagation a…
The Physics of Conformal Cyclic Cosmology
Krzysztof A. Meissner, Roger Penrose
According to conformal cyclic cosmology (CCC), the currently conventional description of the entire history of the universe (but without an initial inflationary phase) provides but…
Standard Model Symmetries and K(E_10)
Krzysztof A. Meissner, Hermann Nicolai
We clarify and extend our earlier work (K.A.Meissner and H.Nicolai, Phys. Rev. D91 (2015) 065029 and Phys. Rev. Lett. 121 (2018) 091601) where it was shown how to amend a scheme or…
Signatures of supermassive charged gravitinos in liquid scintillator detectors
Adrianna Kruk, Michał Lesiuk, Krzysztof A. Meissner +1
In a previous work [K.A. Meissner and H. Nicolai, Eur. Phys. J. C {\bf 84}, 269 (2024)], two of the present authors have suggested possible experimental ways to search for stable s…
Searching for supermassive charged gravitinos in underground experiments
Krzysztof A. Meissner, Hermann Nicolai
We examine possible experimental signatures that may be exploited to search for stable supermassive particles with electric charges of in future underground experiments, and…
