http://arxiv.org/abs/1612.03825 Towards a new paradigm for quark-lepton unification Christopher Smith (Submitted on 12 Dec 2016) My comments: This is my favorite. It is a modification of Minimal Flavor Violation (MFV), a popular philosophy which posits that any BSM couplings may only involve powers of the yukawa matrices. Here the author instead supposes the existence of some functional relation connecting quark and lepton yukawas, and devises criteria for producing desired effects. The standouts for me are (1) connecting the heavy top quark to light leptons (2) the relationship between MFV and holomorphy. http://arxiv.org/abs/1612.03069 Gauge hierarchy problem in asymptotically safe gravity--the resurgence mechanism Christof Wetterich, Masatoshi Yamada (Submitted on 9 Dec 2016) My comments: In a way this is a sequel to the famous 2006 paper which predicted the Higgs boson mass. Here the topic is the hierarchy problem, the smallness of the Higgs mass relative to the Planck scale. Warning, what the authors call "resurgence" has no connection to the concept of resurgence from complex analysis, recently a hot topic in quantum field theory. http://arxiv.org/abs/1611.09797 Radiatively generated hierarchy of lepton and quark masses A. E. Cárcamo Hernández, Sergey Kovalenko, Ivan Schmidt (Submitted on 29 Nov 2016) My comments: In this paper, a judicious choice of symmetries and representations ensures that only the top quark has a tree-level mass. All other fermions get their masses from loop effects. It is not elegant, but it is a proof of concept.
