      The cover page shows an event recorded with the CMS detector (LHC, CERN) in 2012 at a proton-proton centre of mass energy of 8 TeV. It shows characteristics expected from the decay of the standard model (SM) Higgs boson to a pair of photons (dashed yellow lines and green towers). The event could also be due to known SM background processes. (©: CERN, see http://creativecommons.org/licenses/by-sa/3.0/)

    1. The tensor track, III (pages 81–107)

      V. Rivasseau

      Article first published online: 28 NOV 2013 | DOI: 10.1002/prop.201300032

      The author provides an informal up-to-date review of the tensor track approach to quantum gravity. Many recent advances are summarized with emphasis on some rarely discussed points such as the Gromov-Hausdorff limit, the loop vertex expansion, the Osterwalder-Schrader positivity. Open questions and a rather extended bibliography are provided.

    2. On semiclassical four-point correlators in AdS5 × S5 (pages 108–114)

      D. Arnaudov and R.C. Rashkov

      Article first published online: 9 JAN 2014 | DOI: 10.1002/prop.201300033

      Following the recent advances in the holographic calculation of n-point correlation functions with two “heavy” (with large quantum numbers) states at strong coupling, we extend these findings by computing specific contributions to four-point correlators of four heavy BMN operators in N = 4 supersymmetric Yang–Mills theory.

    3. On axionic dark matter in Type IIA string theory (pages 115–151)

      G. Honecker and W. Staessens

      Article first published online: 13 JAN 2014 | DOI: 10.1002/prop.201300036

      Viable scenarios with various axions in the context of supersymmetric field theory and in globally consistent D-brane models are investigated. The Peccei-Quinn symmetry is associated with an anomalous U(1) symmetry, which acquires mass at the string scale but remains as a perturbative global symmetry at low energies. The origin of the scalar Higgs-axion potential from F-, D- and soft breaking terms is derived, and two Standard Model examples of global intersecting D6-brane models in Type II orientifolds are presented.
