A generic prediction in the paradigm of weakly interacting dark matter is the production of relativistic particles from dark matter pair-annihilation in regions of high dark matter density. Ultra-relativistic electrons and positrons produced in the center of the Galaxy by dark matter annihilation [...]

We calculate the set of O(as2) corrections to the branching ratio and to the photon energy spectrum of the decay process [`B] Xsg originating from the interference of diagrams involving the electromagnetic dipole operator O7 with diagrams involving the chromomagnetic dipole operator O8. The [...]

We use gauge/gravity duality to study the thermodynamics of a generic almost conformal theory, specified by its beta function. Three different phases are identified, a high temperature phase of massless partons, an intermediate quasi-conformal phase and a low temperature confining phase. The limit [...]
