 Oscillating propagators in heavy-dense QCD / Akerlund, Oscar ; de Forcrand, Philippe ; Rindlisbacher, Tobias Using Monte Carlo simulations and extended mean field theory calculations we show that the $3$-dimensional $\mathbb{Z}_3$ spin model with complex external fields has non-monotonic correlators in some regions of its parameter space.

 Specialized minimal PDFs for optimized LHC calculations / Carrazza, Stefano (Milan U. ; INFN, Milan ; CERN) ; Forte, Stefano (Milan U. ; INFN, Milan) ; Kassabov, Zahari (Milan U. ; INFN, Milan ; Turin U. ; INFN, Turin) ; Rojo, Juan (Oxford U., Theor. Phys.) We present a methodology for the construction of parton distribution functions (PDFs) designed to provide an accurate representation of PDF uncertainties for specific processes or classes of processes with a minimal number of PDF error sets: specialized minimal PDF sets, or SM-PDFs.

 Aspects of topological actions on the lattice / Akerlund, Oscar (Zurich, ETH) ; de Forcrand, Philippe (Zurich, ETH ; CERN) We consider a lattice action which forbids large fields, and which remains invariant under smooth deformations of the field.

 Research infrastructures in the LHC era: a scientometric approach / Carrazza, Stefano (CERN) ; Ferrara, Alfio (U. Milan (main)) ; Salini, Silvia (U.

 Statistical anisotropy from inflationary magnetogenesis / Giovannini, Massimo (CERN ; INFN, Milan Bicocca) Provided the quantum fluctuations are amplified in the presence of a classical gauge field configuration the resulting curvature perturbations exhibit a mild statistical anisotropy which should be sufficiently weak not to conflict with current observational data.

 Origins of the di-jet asymmetry in heavy ion collisions / Milhano, José Guilherme (Lisbon, CENTRA ; CERN) ; Zapp, Korinna Christine (Lisbon, CENTRA ; CERN) The di-jet asymmetry --- the measure of the momentum imbalance in a di-jet system --- is a key jet quenching observable.

 Comments on the nilpotent constraint of the goldstino superfield / Ghilencea, D M (CERN ; Bucharest, IFIN-HH) Superfield constraints were often used in the past, in particular to describe the Akulov-Volkov action of the goldstino by a superfield formulation with $L=(\Phi^\dagger \Phi)_D + [(f\Phi)_F + h.c.]$ endowed with the nilpotent constraint $\Phi^2=0$ for the goldstino superfield ($\Phi$).
