Pseudoscalar Mediators: A WIMP model at the Neutrino Floor
Giorgio Arcadi, Manfred Lindner, Farinaldo S. Queiroz +2
Due to its highly suppressed cross section (fermionic) dark matter interacting with the Standard Model via pseudoscalar mediators is expected to be essentially unobservable in dire…
Neutrino Parameters from Reactor and Accelerator Neutrino Experiments
Manfred Lindner, Werner Rodejohann, Xun-Jie Xu
We revisit correlations of neutrino oscillation parameters in reactor and long-baseline neutrino oscillation experiments. A framework based on an effective value of is pre…
The Dark Sequential Z' Portal: Collider and Direct Detection Experiments
Giorgio Arcadi, Miguel D. Campos, Manfred Lindner +2
We revisit the status of a Majorana fermion as a dark matter candidate when a sequential Z' gauge boson dictates the dark matter phenomenology. Direct dark matter detection signatu…
Revisiting Large Neutrino Magnetic Moments
Manfred Lindner, Branimir Radovčić, Johannes Welter
Current experimental sensitivity on neutrino magnetic moments is many orders of magnitude above the Standard Model prediction. A potential measurement of next-generation experiment…
Neutrino Masses and Absence of Flavor Changing Interactions in the 2HDM from Gauge Principles
Miguel D. Campos, D. Cogollo, Manfred Lindner +3
We propose several Two Higgs Doublet Models with the addition of an Abelian gauge group which free the usual framework from flavor changing neutral interactions and explain neutrin…
GUT Models at Current and Future Hadron Colliders and Implications to Dark Matter Searches
Giorgio Arcadi, Manfred Lindner, Yann Mambrini +2
Grand Unified Theories (GUT) offer an elegant and unified description of electromagnetic, weak and strong interactions at high energy scales. A phenomenological and exciting possib…
The Waning of the WIMP? A Review of Models, Searches, and Constraints
Giorgio Arcadi, Maíra Dutra, Pradipta Ghosh +5
Weakly Interacting Massive Particles (WIMPs) are among the best-motivated dark matter candidates. In light of no conclusive detection signal yet despite an extensive search program…
Emerging Internal Symmetries from Effective Spacetimes
Manfred Lindner, Sebastian Ohmer
Can global internal and spacetime symmetries be connected without supersymmetry? To answer this question, we investigate Minkowski spacetimes with d space-like extra dimensions and…
Collective neutrino oscillations and neutrino wave packets
Evgeny Akhmedov, Joachim Kopp, Manfred Lindner
Effects of decoherence by wave packet separation on collective neutrino oscillations in dense neutrino gases are considered. We estimate the length of the wave packets of neutrinos…
Atmospheric Trident Production for Probing New Physics
Shao-Feng Ge, Manfred Lindner, Werner Rodejohann
We propose to use atmospheric neutrinos as a powerful probe of new physics beyond the Standard Model via neutrino trident production. The final state with double muon tracks simult…
