Storming Majorana's Tower with OAM states of light in a plasma
We extend the relationship between mass and spin angular momentum, described
by the bosonic spectrum of positive definite mass particles of the Majorana
solution to the Dirac equation, to photons that acquire an effective Proca mass
through the Anderson-Higgs mechanism when they propagate in a plasma. In an
earlier paper we showed that if the plasma is structured, it can impart orbital
angular momentum (OAM) to the photons that reduces the total Proca photon mass.
Here we show, through a generalisation of Majorana's solution, that photons
with OAM in a plasma cannot assume negative squared mass states. This means
that there exist interesting analogies with Quantum Gravity or General
Relativity models involving a modified action of the Lorentz group.Comment: 4 pages; Corrected, updated versio
Apparent Lorentz violation with superluminal Majorana neutrinos at OPERA?
From the data release of OPERA - CNGS experiment, and publicly announced on
23 September 2011, we cast a phenomenological model based on a Majorana
neutrino state carrying a fictitious imaginary mass term, already discussed by
Majorana in 1932. This mass term can be induced by the interaction with the
matter of the Earth's crust during the 735 Km travel. Within the experimental
errors, we prove that the model fits with OPERA, MINOS and supernova SN1987a
data. Possible violations to Lorentz invariance due to quantum gravity effects
have been considered.Comment: 4 pages, 1 figure, 1 table, updated with new data, new figure. Higgs
