EDITORS' SUGGESTION
In a series of two papers, the authors introduce a new method to compute the tree-level -gluon scattering amplitudes in anti-de Sitter spacetime (AdS) space within the AdS/CFT duality. Working with Mellin amplitudes, the authors propose Feynman rules and show that they take a similar form as those in flat space. This intriguing similarity led the authors to propose a novel dictionary: comprehensive rules that bridge AdS Mellin amplitudes with flat-space gluon amplitudes.

Following the Heavy Quark Expansion, this paper computes NLO corrections to the Darwin and four-quark operators for the inclusive semileptonic decays B → X_uℓν¯_ℓ. These corrections are found to be relatively large and will play a role in background subtraction for B → X_cℓν¯_ℓ measurements and better determination of CKM matrix elements.

EDITORS' SUGGESTION
The authors refine and extend the statistical interpretation of the black hole entropy formula to wide classes of black holes such as rotating and charged black holes, including extremal and near-extremal solutions, with or without supersymmetry. They achieve this by constructing a set of black hole microstates with semiclassical interiors that span a Hilbert space of dimension , where is the black hole entropy.
