The paper
Abstract
In this talk I review what we know and don't know about neutrinos, neutrino masses and lepton mixing. I also discuss the importance of the discovery that neutrinos have nonzero masses, and illustrate how little is currently known about the physics behind them.
The paper's own sentences, arranged. Each label is drawn from a closed vocabulary; the number beside it is the probability the classifier gave that label. No sentence in this record was written by a model.

Due to the nature of the $W$-boson interaction, the contributing part of the neutrino propagator (for a recent pedagogical discussion on Feynman diagram computations with Weyl and Majorana fermions see [ref] ) is proportional to the neutrino mass and [equation] where $Q$ is representative of typical neutrino energies and we assumed that these are much larger than the neutrino masses. $m_ee$ is an effective neutrino mass to which neutrinoless double-beta decay experiments are sensitive, and agrees with the $ee$-elelment of the Majorana neutrino mass matrix in the weak-basis where the charged-current and the charged-lepton mass matrices are diagonal. $m_ee$ was discussed in detail in [ref] .

This is the realm of searches for neutrinoless double-beta decay [ref] ; * searches for flavor violation in the lepton sector ($μ→eγ$ [ref] , $μ→e$-conversion in nuclei [ref] , rare tau decays [ref] , etc); * precision measurements of charged and neutral lepton electromagnetic properties, like the $g-2$ of the muon, searches for the electron electric dipole moment or searches for neutrino electromagnetic moments [ref] ; * searches for the physics responsible for electroweak symmetry breaking and new degrees of freedom at the TeV scale.
