 Intrinsic charm in a matched general-mass scheme / Ball, Richard D ; Bertone, Valerio ; Bonvini, Marco ; Forte, Stefano ; Merrild, Patrick Groth ; Rojo, Juan ; Rottoli, Luca The FONLL general-mass variable-flavour number scheme provides a framework for the matching of a calculation in which a heavy quark is treated as a massless parton to one in which the mass dependence is retained throughout.

 A note on the fate of the Landau-Yang theorem in non-Abelian gauge theories / Cacciari, Matteo ; Del Debbio, Luigi ; Espinosa, José R ; Polosa, Antonio D ; Testa, Massimo Using elementary considerations of Lorentz invariance, Bose symmetry and BRST invariance, we argue why the decay of a massive color-octet vector state into a pair of on-shell massless gluons is possible in a non-Abelian SU(N) Yang-Mills theory, we constrain the form of the amplitude of the process and offer a simple understanding of these results in terms of effective-action operators.. arXiv:1509.07853 ; CERN-PH-TH-2015-173. - 2015. - 7 p.

 $\delta N$ formalism from superpotential and holography / Garriga, Jaume ; Urakawa, Yuko ; Vernizzi, Filippo We consider the superpotential formalism to describe the evolution of scalar fields during inflation, generalizing it to include the case with non-canonical kinetic terms.

 Summary and Outlook: 2015 Lepton-Photon Symposium / Ellis, John What life is there after Higgs? Specifically, what physics lies beyond the Standard Model (SM)?

 Introduction to SARAH and related tools / Staub, Florian I give in this lecture an overview of the features of the Mathematica package SARAH, and explain how it can be used together with other codes to study all aspects of a BSM model.

 Minimal scalar-less matter-coupled supergravity / Dall'Agata, Gianguido (Padua U., Astron. Dept. ; Padua U. ; INFN, Padua ; Ecole Polytechnique, CPHT) ; Ferrara, Sergio (CERN ; Frascati ; UCLA) ; Zwirner, Fabio (Padua U., Astron. Dept. ; Padua U. ; INFN, Padua ; CERN) We build the minimal supergravity model where the nilpotent chiral goldstino superfield is coupled to a chiral matter superfield, realising a different non-linear representation through a mixed nilpotency constraint.
