Quantum Magic Reveals CP Phases Invisible to Entanglement in Spin-0 Decays
Nicolas Viaux, Ariel Norambuena, Pedro Orellana
All standard scalar quantum-information measures -- concurrence, negativity, entanglement entropy, the optimized CHSH bound, and quantum Fisher information -- are CP-blind in ideal…
Non-Monotonic Rotation Imprint on Time-Integrated Neutrino Spectral Moments in a 15\, Core-Collapse Supernova Sequence
Nicolas Viaux
We study the early post-bounce neutrino signal of the published Garching rotating core-collapse supernova (CCSN) sequence consisting of non-rotating (NR), slowly rota…
An Analytic Threshold for LESA-Driven Negative ELN Flux Directions in Core-Collapse Supernovae: Derivation and Population Census
Nicolás Viaux, Lucas Johns
In core-collapse supernovae (CCSNe), deleptonization normally favors over emission. However, lepton-number emission self-sustained asymmetry (LESA) can make the e…
Operator Identification in Charged Lepton-Flavor Violation: Global EFT Analysis with RG Evolution, Polarization Observables, and Bayesian Model Discrimination at Future Colliders
Nicolás Viaux M
Charged lepton-flavor violation is a null-test frontier of the Standard Model and a direct probe of physics beyond it. We present a global effective field theory (EFT) analysis acr…
Which Neutron Stars Reach the Stiffening Regime? Multimessenger Constraints on Core Sound Speed and Stellar-Mass Thresholds
Nicolás Viaux, Sebastián Mendizabal
We present a concise multimessenger inference of the neutron-star core sound-speed profile using GW170817 and three \textit{NICER} mass--radius posteriors (PSR J00300451, PSR J0…
Prospects for dark matter observations in dwarf spheroidal galaxies with the Cherenkov Telescope Array Observatory
K. Abe, S. Abe, J. Abhir +491
The dwarf spheroidal galaxies (dSphs) orbiting the Milky Way are widely regarded as systems supported by velocity dispersion against self-gravity, and as prime targets for the sear…
