The discovery of neutrinoless β β decay could soon be within reach. This hypothetical
ultrarare nuclear decay offers a privileged portal to physics beyond the standard model of …

The nature of dark matter and properties of neutrinos are among the most pressing issues in
contemporary particle physics. The dual-phase xenon time-projection chamber is the …

The nEXO neutrinoless double beta (0νββ) decay experiment is designed to use a time
projection chamber and 5000 kg of isotopically enriched liquid xenon to search for the decay …

In the space of less than one decade, the search for Majorana quasiparticles in condensed
matter has become one of the hottest topics in physics. The aim of this review is to provide a …

The nuclear matrix elements that govern the rate of neutrinoless double beta decay must be
accurately calculated if experiments are to reach their full potential. Theorists have been …

This review demonstrates the unique role of the neutrino by discussing in detail the physics
of and with neutrinos. We deal with neutrino sources, neutrino oscillations, absolute masses …

The observation of neutrinoless double-beta decay (0νββ) would show that lepton number is
violated, reveal that neu-trinos are Majorana particles, and provide information on neutrino …

Ettore Majorana (1906–1938) disappeared while traveling by ship from Palermo to Naples
in 1938. His fate has never been fully resolved and several articles have been written that …

Most of the free parameters in the Standard Model (SM)—a quantum field theory which has
successfully elucidated the behaviors of strong, weak and electromagnetic interactions of all …

The 1937 theoretical discovery of Majorana fermions—whose defining property is that they
are their own anti-particles—has since impacted diverse problems ranging from neutrino …
