A normal form for bases of finite-dimensional vector spaces
Patrick Otto Ludl
Most algorithms constructing bases of finite-dimensional vector spaces return basis vectors which, apart from orthogonality, do not show any special properties. While every basis i…
Supersymmetric Majoron Inflation
Stephen F. King, Patrick Otto Ludl
We propose supersymmetric Majoron inflation in which the Majoron field responsible for generating right-handed neutrino masses may also be suitable for giving low scale "hillto…
Unifying leptogenesis, dark matter and high-energy neutrinos with right-handed neutrino mixing via Higgs portal
Pasquale Di Bari, Patrick Otto Ludl, Sergio Palomares-Ruiz
We revisit a model in which neutrino masses and mixing are described by a two right-handed (RH) neutrino seesaw scenario, implying a strictly hierarchical light neutrino spectrum.…
Direct and Semi-Direct Approaches to Lepton Mixing with a Massless Neutrino
Stephen F. King, Patrick Otto Ludl
We discuss the possibility of enforcing a massless Majorana neutrino in the direct and semi-direct approaches to lepton mixing, in which the PMNS matrix is partly predicted by subg…
Direct Neutrino Mass Experiments and Exotic Charged Current Interactions
Patrick Otto Ludl, Werner Rodejohann
We study the effect of exotic charged current interactions on the electron energy spectrum in tritium decay, focussing on the KATRIN experiment and a possible modified setup that h…
Lepton mixing from the hidden sector
P. O. Ludl, A. Yu. Smirnov
Experimental results indicate a possible relation between the lepton and quark mixing matrices of the form U_PMNS \approx V_CKM^\dagger U_X, where U_X is a matrix with special stru…
