Massive three-loop form factors: anomaly contribution / Fael, Matteo (CERN) ; Lange, Fabian (KIT, Karlsruhe, TTP ; KIT, Karlsruhe, IAP) ; Schönwald, Kay (Zurich U.) ; Steinhauser, Matthias (KIT, Karlsruhe, TTP)
We compute three-loop corrections to the singlet form factors for massive quarks using a semi-analytic method which provides precise results over the whole kinematic range. [...]

Symmetry plane correlations in Pb-Pb collisions at $\sqrt{s_{\rm NN}} = 2.76$TeV
A newly developed observable for correlations between symmetry planes, which characterize the direction of the anisotropic emission of produced particles, is measured in Pb-Pb collisions at $\sqrt{s_{\rm NN}} = 2.76$ TeV with ALICE. [...]

Gravitoelectromagnetic quadrirefringence and the binaries rainbow / Romano, Antonio Enea (King's Coll. London ; CERN ; ICRA, Pescara) ; Vallejo-Peña, Sergio A. (ICRA, Pescara)
The interaction between gravitational waves (GW) and electromagnetic waves (EMW) produces quadrirefringence, a phenomenon consisting in a frequency and polarization dependency of the speed of GW and EMW. [...]

A unified effective approach to cosmological perturbations / Romano, Antonio Enea (ICRA, Pescara)
A unified model independent effective description of cosmological perturbations is derived in terms of two effective quantities, playing the role of effective propagation speeds of curvature perturbations and gravitational waves, encoding the effects of the interaction of perturbations at any order, and inducing a modification of the friction term of the perturbations propagation equation.
