Maximal-Helicity-Violating n-Point One-Loop Amplitude in [script N]=4 Supergravity
David C. Dunbar, James H. Ettle, and Warren B. Perkins
We propose an explicit formula for the n-point maximal-helicity-violating one-loop amplitude in a [script N]=4 supergravity theory. This formula is derived from the soft and collinear factorizations of the amplitude. ... [Phys. Rev. Lett. 108, 061603 ] published .
Anomalous hydrodynamics for chiral superfluid
Shu Lin
Starting from a low energy effective chiral Lagrangian with a gauged Wess-Zumino-Witten term, we have derived a hydrodynamic theory for chiral superfluid. It is a non-Abelian hydrodynamics at zero temperature with only superfluid components. With an external electromagnetic field and baryonic and ax ... [Phys. Rev. D 85, 045015 ] published .
Supersymmetric Higgs searches: Beyond the MSSM
F. Boudjema and G. Drieu La Rochelle
The recent results from the ATLAS and CMS Collaborations show that the allowed range for a standard model Higgs boson is now restricted to a very thin region, if one excludes a very heavy Higgs. Although those limits are presented exclusively in the framework of the standard model, the searches them ... [Phys. Rev. D 85, 035011 ] published .
Classification and analysis of Higgs-flavor models
S. M. Barr and Thomas W. Kephart
A classification is given of models in which there are several Higgs SU(2) doublets that form an irreducible multiplet of a non-Abelian symmetry G, under which the quarks and leptons do not transform (thus giving minimal flavor changing for the fermions). It is found that different groups G and irre ... [Phys. Rev. D 85, 035010 ] published .
