Collective neutrino oscillations: Many-body non-forward effects and non-classicality
Julien Froustey, Ermal Rrapaj, Yuhao Liu +3
Neutrino evolution in dense astrophysical environments is typically described either within a quantum kinetic framework, which neglects the build-up of multi-body correlations, or…
Neutrino-less double beta decay in the Standard Model
Vincenzo Cirigliano, Wouter Dekens, Sebastián Urrutia Quiroga
We perform a comprehensive study of the Type-I seesaw model for a broad range of right-handed mass scales (from keV to 10 TeV). We take into account and, in some cases, updat…
Neutrinoless double beta decay with light sterile neutrinos: the contact terms
Vincenzo Cirigliano, Wouter Dekens, Sebastián Urrutia Quiroga
We study neutrinoless double-beta decay in extensions of the Standard Model that include right-handed neutrino singlets, with masses below the GeV scale. Generalizing rec…
Effective field theory for radiative corrections to charged-current processes II: Axial-vector coupling
Vincenzo Cirigliano, Wouter Dekens, Emanuele Mereghetti +1
We discuss the hadronic structure-dependent radiative corrections to the axial-vector coupling that controls single-nucleon weak charged-current processes -- commonly denoted by $g…
Unique forbidden beta decays at zero momentum transfer
Chien-Yeah Seng, Ayala Glick-Magid, Vincenzo Cirigliano
We report an exploratory study of the structure-dependent electromagnetic radiative corrections to unique first-forbidden nuclear beta decays. We show that the in…
Neutrino many-body flavor evolution: the full Hamiltonian
Vincenzo Cirigliano, Srimoyee Sen, Yukari Yamauchi
We study neutrino flavor evolution in the quantum many-body approach using the full neutrino-neutrino Hamiltonian, including the usually neglected terms that mediate non-forward sc…
