Acitelli 22, 67100 Assergi (AQ), Italy (Dated: April 20, 2016) The discovery of neutrino masses through the observation of oscillations boosted the importance of neutrinoless double beta decay (0νββ). In this paper, we review the main features of this process, underlining its key role both from the experimental and theoretical point of view. In particular, we contextualize the 0νββ in the panorama of lepton-number violating processes, also assessing some possible particle physics mechanisms mediating the process. Since the 0νββ existence is correlated with neutrino masses, we also review the state-of-art of the theoretical understanding of neutrino masses. In the final part, the status of current 0νββ experiments is presented and the prospects for the future hunt for 0νββ are discussed. Also, experimental data coming from cosmological surveys are considered and their impact on 0νββ expectations is examined. PACS numbers: 14.60.Pq,23.40.-s DOI: 10.1155/2016/2162659 u u I.

  • Via Panisperna Boys”: the Role of Ettore Majorana
    JCOM 1 (3), September 2002 Science Communication and the “via Panisperna boys”: the Role of Ettore Majorana Angelo Mastroianni Università degli Studi “La Sapienza” di Roma Enrico Fermi’s work gave birth to a real cultural revolution in the Italian scientific scenario. His scientific studies concerned almost every field in physics and had far-reaching effects of which virtually everybody, above all in Italy, is still taking advantage. Two important “by-products” of Fermi’s ideas and initiatives will be here taken into consideration: the new way of carrying out research and communicating science invented by Fermi and his group and his publications for the general public, which often stood for high examples of scientific popularisation. Then the focus will shift on Ettore Majorana’s role to try to understand why his work in the field of communication within the School of Physics of Rome was basically non-existent despite the excellent communicative skills he demonstrated both during his university lectures – also published in this magazine – and in his article “Il valore delle leggi statistiche nella fisica e nelle scienze sociali” [20], the only one which does not deal with pure physics issues and which will be also taken into account in this paper Fermi’s Cultural Revolution In the first thirty years of the 1900s, two important innovations were introduced in the field of modern physics: the theory of relativity and quantum mechanics. The promoters of both these changes were born or worked in Central Europe, except Gregorio Ricci Curbastro and Tullio Levi Civita (Italy), Satyendra Nath Bose (India), Arthur Holly Compton and Alfred Landè (USA, but the latter 1 was of German origin).

    Majorana neutrinos and other Majorana particles: Theory and experiment Evgeny Kh. Akhmedov∗† Max-Planck-Institut f¨ur Kernphysik, Saupfercheckweg 1 D-69117 Heidelberg, Germany Abstract This is a somewhat modified version of Chapter 15 of the book “The Physics of Ettore Majorana”, by Salvatore Esposito with contributions by Evgeny Akhmedov (Ch. 15) and Frank Wilczek (Ch. 14), Cambridge University Press, 2014. arXiv:1412.3320v1 [hep-ph] 10 Dec 2014 ∗Also at the National Research Centre Kurchatov Institute, Moscow, Russia †email: [email protected] What are Majorana particles? These are massive fermions that are their own antipar- ticles. In this chapter we will concentrate on spin-1/2 Majorana particles, though fermions of higher spin can also be of Majorana nature. Obviously, Majorana particles must be genuinely neutral, i.e. they cannot possess any conserved charge-like quantum number that would allow one to discriminate between the particle and its antiparticle. In particular, they must be electrically neutral. Among the known spin-1/2 particles, only neutrinos can be of Majorana nature. Another known quasi-stable neutral fermion, the neutron, has non-zero magnetic moment which disqualifies it for being a Majorana particle: the antineutron exists, and its magnetic moment is negative of that of the neutron1. Neutrinos are exactly massless in the original version of the standard model of elec- troweak interaction, and are massive Majorana particles in most its extensions. Although massive Dirac neutrinos is also a possibility, most economical and natural models of neutrino mass lead to Majorana neutrinos. Since only massive neutrinos can oscillate, the interest to the possibility of neutrinos being Majorana particles rose significantly after the first hints of neutrino oscillations obtained in the solar and atmospheric neutrino experiments.
