We define and compute the energy of higher curvature gravity theories in arbitrary dimensions. Generically, these theories admit constant curvature vacua (even in the absence of an explicit cosmological constant), and asymptotically constant curvature solutions with nontrivial energy properties. For concreteness, we s…

We report on a revision of our previous computation of the renormalized expectation value of the stress-energy tensor of a massless, minimally coupled scalar with a quartic self-interaction on a locally de Sitter background. This model is important because it demonstrates that quantum effects can lead to violations of…

We derive a simple form for the propagator of a massless, minimally coupled scalar in a locally de Sitter geometry of arbitrary spacetime dimension. We then employ it to compute the fully renormalized stress tensor at one- and two-loop orders for a massless, minimally coupled ϕ 4 theory which is released in Bunch–Davi…

We drop the complexification procedure from the Newman-Janis algorithm and introduce more physical arguments and symmetry properties, and we show how one can generate regular and singular rotating black hole and non-black-hole solutions in Boyer-Lindquist coordinates. We focus on generic rotating regular black holes a…

The isospin asymmetries of B → Kµ + µ -and B → K * µ + µ -decays and the partial branching fractions of the B 0 → K 0 µ + µ -, B + → K + µ + µ -and B + → K * + µ + µ - decays are measured as functions of the dimuon mass squared, q 2 .The data used correspond to an integrated luminosity of 3 fb -1 from proton-proton co…
