Combining neutrino oscillation experiments with the Feldman–Cousins method
In this paper we describe how two or more experimental results can be combined within the procedure of Feldman and Cousins, to provide combined confidence limits on the physical parameters of interest. We demonstrate the technique by combining the recent electron neutrino appearance results from T2K and MINOS. Our best fit point is sin2 2θ13 = 0.08 (0.11) and δ = 1.1 (2.0)π; in addition we exclude sin2 2θ13 = 0 at 2.7σ (2.8σ) for the normal (inverted) neutrino mass hierarchy.

Covariant constraints for generic massive gravity and analysis of its characteristics
We perform a covariant constraint analysis of massive gravity valid for its entire parameter space, demonstrating that the model generically propagates 5 degrees of freedom; this is also verified by a new and streamlined Hamiltonian description. The constraint’s covariant expression permits computation of the model’s caustics. Although new features such as the dynamical Riemann tensor appear in the characteristic matrix, the model still exhibits the pathologies uncovered in earlier work: superluminality and likely acausalities.

On the renormalizability and unitarity of the Curci-Ferrari model for massive vector bosons
Abstract We prove the renormalizability of the Curci-Ferrari model with and without auxiliary fields using BRST methods. In both cases we find five Z factors instead of three. We verify our results by explicit one-loop calculations. We determine a set of generators for the “physical states”, many of which have negative norm. Supersymmetrization is considered.

(p,q)-form Kähler electromagnetism
We present a gauge invariant generalization of Maxwell's equations and p-form electromagnetism to Kahler manifolds. The result is a detour operator connecting Dolbeault and dual Dolbeault cohomologies and derives from BRST detour quantization of the N=4 supersymmetry algebra. The form of the new equations mimics the linearized Einstein's equations and extends to more general geometric structures.
