Exotic Higgs boson decay modes as a harbinger of flavor symmetry
Discrete symmetries employed to explain flavor mixing and mass hierarchies
can be associated with an enlarged scalar sector which might lead to exotic
Higgs decay modes. In this paper, we explore such a possibility in a scenario
with flavor symmetry which requires three scalar SU(2) doublets. The
spectrum is fixed by minimizing the scalar potential, and we observe that the
symmetry of the model leads to tantalizing Higgs decay modes potentially
observable at the CERN Large Hadron Collider (LHC).Comment: v2: 7 pages, 5 eps figures, to appear as a Rapid Communication in

A common origin of fermion mixing and geometrical CP violation, and its test through Higgs physics at the LHC
We construct for the first time a flavor model, based on the smallest
discrete symmetry Delta(27) that implements spontaneous CP violation with a
complex phase of geometric origin, which can actually reproduce all quark
masses and mixing data. We show that its scalar sector has exotic properties
that can be tested at the LHC.Comment: v3: accepted by PR
Geometrical CP violation from non-renormalisable scalar potentials
We consider in detail the non-renormalisable scalar potential of three Higgs
doublets transforming as an irreducible triplet of Delta(27) or Delta(54). We
start from a renormalisable potential that spontaneously leads to a vacuum with
CP-violating phases independent of arbitrary parameters - geometrical CP
violation. Then we analyse to arbitrarily high order non-renormalisable terms
that are consistent with the symmetry and we demonstrate that inclusion of
non-renormalisable terms in the potential can preserve the geometrical
CP-violating vacuum.Comment: 5 pages, 2 figures. v2: references added, accepted by PL
The future of dialects: Selected papers from Methods in Dialectology XV
Traditional dialects have been encroached upon by the increasing mobility of their speakers and by the onslaught of national languages in education and mass media. Typically, older dialects are “leveling” to become more like national languages. This is regrettable when the last articulate traces of a culture are lost, but it also promotes a complex dynamics of interaction as speakers shift from dialect to standard and to intermediate compromises between the two in their forms of speech. Varieties of speech thus live on in modern communities, where they still function to mark provenance, but increasingly cultural and social provenance as opposed to pure geography. They arise at times from the need to function throughout the different groups in society, but they also may have roots in immigrants’ speech, and just as certainly from the ineluctable dynamics of groups wishing to express their identity to themselves and to the world.
The future of dialects is a selection of the papers presented at Methods in Dialectology XV, held in Groningen, the Netherlands, 11-15 August 2014. While the focus is on methodology, the volume also includes specialized studies on varieties of Catalan, Breton, Croatian, (Belgian) Dutch, English (in the US, the UK and in Japan), German (including Swiss German), Italian (including Tyrolean Italian), Japanese, and Spanish as well as on heritage languages in Canada
