Asymptotic Balance and Structural Rigidity in the Riemann Zeta Function

Pedro Caceres

We establish a structural rigidity principle for the nontrivial zeros of the Riemann zeta function by analyzing the asymptotic interaction between discrete Dirichlet oscillations a…

Study of $β$ Decay Shape Factors in First-Forbidden Transitions with $Δ I^{π} = 0^{-}$ for Reactor Antineutrino Spectra Predictions

G. A. Alcalá, A. Algora, M. Estienne +36

The electron spectra of the $β$ decays of $^{92}$ Rb and $^{142}$ Cs, key contributors to the reactor antineutrino spectrum, were measured at the IGISOL facility using radioactive be…

Quantum Computing Demonstration of the Polaron-Molecule Transition on a NISQ Device

Hugo Catala, Ezequiel Valero, German Rodrigo

The simulation of strongly correlated fermionic systems remains a significant challenge in computational physics due to the exponential growth of the Hilbert space and the fermioni…

Study of beta spectrum shapes relevant to the prediction of reactor antineutrino spectra

G. A. Alcalá, A. Algora, M. Estienne +35

The shapes of the beta spectra of 92Rb and 142Cs, two of the beta decays most relevant for the prediction of the antineutrino spectrum in reactors, have been measured. A new setup…

Effective field theory analysis of rare $∣Δ c ∣ = ∣Δ u ∣ = 1$ charm decays

Hector Gisbert, Gudrun Hiller, Dominik Suelmann

We perform a global analysis of $∣Δ c ∣ = ∣Δ u ∣ = 1$ transitions using recent data on $D^{0} \to μ^{+} μ^{-}$ , $D^{+} \to π^{+} μ^{+} μ^{-}$ , $Λ_{c} \to p μ^{+} μ^{-}$ , and $D^{0} \to π^{+} π^{-} μ^{+} μ^{-}$ decays…

Axion Window on New Macroscopic Forces

Luca Di Luzio, Hector Gisbert, Fabrizio Nesti +1

Axion-mediated forces are enhanced by the presence of CP-violating axion couplings, which are however tightly constrained by electric dipole moment (EDM) searches. We discuss the u…
