 2019-05-1312:42 [PUBDB-2019-02236] Talk (non-conference) (Invited) Nieri, F. Supersymmetric localisation of 4d $\mathcal{N} =$ 1 theories on $D^2 \times T^2$ String Theory seminar, University of GroningenGroningen, University of Groningen, The Nederlands, 9 May 2019 - 9 May 2019   Since the pioneering work of Pestun, localization techniques have been successfully applied to computing protected observables in theories with varying amounts of supersymmetry and in diverse dimensions and backgrounds. For theories with N=1 supersymmetry in four dimensions, most of the studies have focused on closed compact spaces, while only few results for manifolds with boundaries are available, mostly in two and three dimensions.

ALP Hints from Pulsar and Supernova Remnant Spectra ALPS Collaboration Meeting, DESYHamburg, DESY, Germany, 8 May 2019 - 10 May 2019   OpenAccess: PDF; 2019-05-0815:41 [PUBDB-2019-02208] Talk (non-conference) (Invited) Domcke, V. F. Particle Production in the Early Universe GRAPPA Seminar, GRAPPA, AmsterdamGRAPPA, Amsterdam, 2 May 2019   The paradigm of cosmic inflation explains our observations of the cosmic microwave background spectacularly well. To proceed in the quest of pinning down the particle physics model behind this very early phase of the Universe, multi-wavelength observations of the power spectra of the anisotropies generated during cosmic inflation are crucial.

We begin by reviewing four-dimensional dS space. [...] OpenAccess: PDF; External link: Fulltext 2019-05-0216:45 [PUBDB-2019-02137] Talk (non-conference) (Invited) Westphal, A. Accelerated expansion in string theory? - Backreaction issues in KKLT and large field inflation Seminar, Harvard UniversityBoston, Harvard University, USA, 22 Apr 2019 - 22 Apr 2019   It is notoriously difficult to engineer successful models of inflation and late time expansion in string theory. We discuss what are generic difficulties encountered in string model building and emphasize the particular role played by the KKLT proposal in the recent debate surrounding the "no-dS conjecture".
