beta">desintegración beta</a> del <a href="/wiki/Reacci%C3%B3n_nuclear" class="mw-redirect" title="Reacción nuclear">núcleo</a>. Tienen un <a href="/wiki/Esp%C3%ADn" title="Espín">spin</a> de 1/2, y son parte de la familia de partículas de los <a href="/wiki/Lept%C3%B3n" title="Leptón">leptones</a>. Los antineutrinos observados hasta ahora todos tienen <a href="/w/index.php?title=Helicicidad&action=edit&redlink=1" class="new" title="Helicicidad (aún no redactado)">helicicidad</a> hacia la derecha (es decir, solo uno de los dos posibles estados del spin se ha visto), mientras que el de los <a href="/wiki/Neutrino" title="Neutrino">neutrinos</a> son a la izquierda.

Las partículas que tienen esta propiedad se llaman <a href="/wiki/Ecuaci%C3%B3n_de_Majorana" title="Ecuación de Majorana">partículas de Majorana</a>. Si los neutrinos fueran ciertamente partículas de Majorana entonces el proceso de <a href="/wiki/Doble_desintegraci%C3%B3n_beta" title="Doble desintegración beta">doble desintegración beta</a> está permitido. Se han propuesto distintos experimentos para buscar la ocurrencia de este proceso. </p><p>El <a href="/wiki/Laboratorio_Nacional_Sandia" class="mw-redirect" title="Laboratorio Nacional Sandia">Laboratorio Nacional Sandia</a> está investigando el uso de los detectores de antineutrinos para monitorear <a href="/wiki/Reactor_nuclear" title="Reactor nuclear">reactores nucleares</a>, y para detectar un muy bajo rendimiento en <a href="/wiki/Prueba_nuclear" title="Prueba nuclear">pruebas nucleares</a>; estas pruebas con rendimiento menor a 1 <a href="/wiki/Kilot%C3%B3n" class="mw-redirect" title="Kilotón">kilotón</a> son difíciles de detectar usando detectores convencionales <a href="/w/index.php?title=S%C3%ADsmico&action=edit&redlink=1" class="new" title="Sísmico (aún no redactado)">sísmicos</a> si métodos evasivos como por ejemplo es usado el desemparejamiento sísmico.
