Insights on the Scale of Leptogenesis from Neutrino Masses and Neutrinoless Double-Beta Decay
Alessandro Granelli, Koichi Hamaguchi, Maura E. Ramirez-Quezada +3
We revisit the thermal leptogenesis scenario in the type-I seesaw framework featuring three heavy Majorana neutrinos with a hierarchical mass spectrum. We focus on low energy obser…
Geometric conservation in curved spacetime and entropy
Sinya Aoki, Yoshimasa Hidaka, Kiyoharu Kawana +1
We provide an improved definition of new conserved quantities derived from the energy-momentum tensor in curved spacetime by introducing an additional scalar function. We find that…
Derivation of the GKP-Witten relation by symmetry without Lagrangian
Sinya Aoki, Janos Balog, Kengo Shimada
We derive the GKP-Witten relation in terms of correlation functions by symmetry without referring to a Lagrangian or the large expansion. By constructing bulk operators from bo…
AdS/CFT correspondence for the invariant critical model in 3-dimensions by the conformal smearing
Sinya Aoki, Kiyoharu Kawana, Kengo Shimada
We investigate a structure of a 4-dimensional bulk space constructed from the invariant critical model in 3-dimension using the conformal smearing. We calculate a bul…
