	Author	Centelles Chulia, S.; Cepedello, R.; Peinado, E.; Srivastava, R.
	Title	Systematic classification of two-loop d=4 Dirac neutrino mass models and the Diracness-dark matter stability connection			Type	Journal Article
	Year	2019	Publication	Journal of High Energy Physics	Abbreviated Journal	J. High Energy Phys.
	Volume	10	Issue	10	Pages	093 - 33pp
	Keywords	Beyond Standard Model; Neutrino Physics
	Abstract	We provide a complete systematic classification of all two-loop realizations of the dimension four operator for Dirac neutrino masses. Our classification is multi-layered, starting first with a classification in terms of all possible distinct two loop topologies. Then we discuss the possible diagrams for each topology. Model-diagrams originating from each diagram are then considered. The criterion for genuineness is also defined and discussed at length. Finally, as examples, we construct two explicit models which also serve to highlight the intimate connection between the Dirac nature of neutrinos and the stability of dark matter.

	Title	Constraining neutrinoless double beta decay			Type	Journal Article
	Year	2012	Publication	Nuclear Physics B	Abbreviated Journal	Nucl. Phys. B
	Volume	861	Issue	3	Pages	259-270
	Keywords
	Abstract	A class of discrete flavor-symmetry-based models predicts constrained neutrino mass matrix schemes that lead to specific neutrino mass sum-rules (MSR). We show how these theories may constrain the absolute scale of neutrino mass, leading in most of the cases to a lower bound on the neutrinoless double beta decay effective amplitude.

	Title	New neutrino mass sum rule from the inverse seesaw mechanism			Type	Journal Article
	Year	2012	Publication	Physical Review D	Abbreviated Journal	Phys. Rev. D
	Volume	86	Issue	5	Pages	056001 - 9pp
	Keywords
	Abstract	A class of discrete flavor-symmetry-based models predicts constrained neutrino mass matrix schemes that lead to specific neutrino mass sum rules. One of these implies a lower bound on the effective neutrinoless double beta mass parameter, even for normal hierarchy neutrinos. Here we propose a new model based on the S-4 flavor symmetry that leads to the new neutrino mass sum rule and discuss how to generate a nonzero value for the reactor angle theta(13) indicated by recent experiments, and the resulting correlation with the solar angle theta(12).

	Author	Hirsch, M.; Morisi, S.; Peinado, E.; Valle, J.W.F.
	Title	Discrete dark matter			Type	Journal Article
	Year	2010	Publication	Physical Review D	Abbreviated Journal	Phys. Rev. D
	Volume	82	Issue	11	Pages	116003 - 5pp
	Keywords
	Abstract	We propose a new motivation for the stability of dark matter (DM). We suggest that the same non-Abelian discrete flavor symmetry which accounts for the observed pattern of neutrino oscillations, spontaneously breaks to a Z(2) subgroup which renders DM stable. The simplest scheme leads to a scalar doublet DM potentially detectable in nuclear recoil experiments, inverse neutrino mass hierarchy, hence a neutrinoless double beta decay rate accessible to upcoming searches, while theta(13) = 0 gives no CP violation in neutrino oscillations.

	Author	King, S.F.; Morisi, S.; Peinado, E.; Valle, J.W.F.
	Title	Quark-lepton mass relation in a realistic A(4) extension of the Standard Model			Type	Journal Article
	Year	2013	Publication	Physics Letters B	Abbreviated Journal	Phys. Lett. B
	Volume	724	Issue	1-3	Pages	68-72
	Keywords
	Abstract	We propose a realistic A(4) extension of the Standard Model involving a particular quark-lepton mass relation, namely that the ratio of the third family mass to the geometric mean of the first and second family masses are equal for down-type quarks and charged leptons. This relation, which is approximately renormalization group invariant, is usually regarded as arising from the Georgi-Jarlskog relations, but in the present model there is no unification group or supersymmetry. In the neutrino sector we propose a simple modification of the so-called Zee-Wolfenstein mass matrix pattern which allows an acceptable reactor angle along with a deviation of the atmospheric and solar angles from their bi-maximal values. Quark masses, mixing angles and CP violation are well described by a numerical fit.
