Neutrinoless double-beta decay is a forbidden, lepton-number-violating nuclear transition
whose observation would have fundamental implications for neutrino physics, theories …

Neutrino–nuclear responses associated with astro-neutrinos, single beta decays and double
beta decays are crucial in studies of neutrino properties of interest for astro-particle physics …

The amplitude for the neutrinoless double β (0 ν β β) decay of the two-neutron system nn→
ppe-e-constitutes a key building block for nuclear-structure calculations of heavy nuclei …

Over the last decade, numerical solutions of Quantum Chromodynamics (QCD) using the
technique of lattice QCD have developed to a point where they are beginning to connect …

The observation of neutrino oscillations and hence non-zero neutrino masses provided a
milestone in the search for physics beyond the Standard Model. But even though we now …

The process at the heart of neutrinoless double-β decay, nn→ ppe− e− induced by a light
Majorana neutrino, is investigated in pionless and chiral effective field theory. We show in …

A bstract We present a method to determine the leading-order (LO) contact term contributing
to the nn→ ppe− e− amplitude through the exchange of light Majorana neutrinos. Our …

A bstract We present a master formula describing the neutrinoless-double-beta decay (0νββ)
rate induced by lepton-number-violating (LNV) operators up to dimension nine in the …

A bstract We investigate neutrinoless double beta decay (0νββ) in the presence of sterile
neutrinos with Majorana mass terms. These gauge-singlet fields are allowed to interact with …

We present the first realistic lattice QCD calculation of the γ W-box diagrams relevant for
beta decays. The nonperturbative low-momentum integral of the γ W loop is calculated using …
