Beyond lepton number violation at the HL-LHC: Resolving heavy neutrino-antineutrino oscillations
Stefan Antusch, Jan Hajer, Johannes Rosskopp
Collider testable low-scale seesaw models predict pseudo-Dirac heavy neutrinos, that can produce an oscillating pattern of lepton number conserving and lepton number violating even…
CP-odd and CP-even Weak-Basis Invariants in the Presence of Vector-Like Quarks
Francisco Albergaria, G. C. Branco, José Filipe Bastos +1
We propose a minimal set of weak-basis invariants in an extension of the SM where one up-type isosinglet vector-like quark is introduced, which allows us to obtain all the physical…
Simulating lepton number violation induced by heavy neutrino-antineutrino oscillations at colliders
Stefan Antusch, Jan Hajer, Johannes Rosskopp
We study pseudo-Dirac pairs of two almost mass-degenerate sterile Majorana neutrinos which generate light neutrino masses via a low-scale seesaw mechanism. These pseudo-Dirac heavy…
Axionic Dirac seesaw and electroweak vacuum stability
J. T. Penedo, Yakefu Reyimuaji, Xinyi Zhang
We explore the connection between tree-level Dirac neutrino masses and axion physics in a scenario where the PQ symmetry enforces lepton number conservation perturbatively. Requiri…
Do the Small Numbers in the Quark Mixing arise from New Physics?
G. C. Branco, José Filipe Bastos, J. I. Silva-Marcos
We put forward the conjecture that the small numbers in the matrix, are generated by physics beyond the Standard Model. We identify as small numbers and the…
Dark matter in a CP-violating three-Higgs-doublet model with symmetry
A. Kunčinas, O. M. Ogreid, P. Osland +1
In spite of the success of the Standard Model of Particle Physics, there are some theoretical predictions which are not yet fully established experimentally as well as some experim…
