 The Super-GUT CMSSM Revisited / Ellis, John ; Evans, Jason L ; Mustafayev, Azar ; Nagata, Natsumi ; Olive, Keith A We revisit minimal supersymmetric SU(5) grand unification (GUT) models in which the soft supersymmetry-breaking parameters of the minimal supersymmetric Standard Model (MSSM) are universal at some input scale, $M_{in}$, above the supersymmetric gauge coupling unification scale, $M_{GUT}$.

 Two-loop scale-invariant scalar potential and quantum effective operators / Ghilencea, D M ; Lalak, Z ; Olszewski, P Spontaneous breaking of quantum scale invariance may provide a solution to the hierarchy and cosmological constant problems.

 Chiral Heterotic Strings with Positive Cosmological Constant / Florakis, Ioannis ; Rizos, John We present explicit examples of semi-realistic heterotic models with spontaneously broken supersymmetry, which dynamically lead to breaking scales much smaller than $M_{\rm Planck}$ and exponentially small positive values for the cosmological constant.

 On gravitational and thermal corrections to vacuum decay / Salvio, Alberto ; Strumia, Alessandro ; Tetradis, Nikolaos ; Urbano, Alfredo We reconsider gravitational corrections to vacuum decay, confirming and simplifying earlier results and extending them allowing for a non-minimal coupling of the Higgs to gravity, finding that leading-order gravitational corrections suppress the vacuum decay rate.

 Monte Carlo simulations of Higgs-boson production at the LHC with the KrkNLO method / Jadach, S ; Nail, G ; Placzek, W ; Sapeta, S ; Siodmok, A ; Skrzypek, M We present numerical tests and predictions of the KrkNLO method for matching of NLO QCD corrections to hard processes with LO parton shower Monte Carlo generators.

 Renormalization-group flow of the effective action of cosmological large-scale structures / Floerchinger, Stefan ; Garny, Mathias ; Tetradis, Nikolaos ; Wiedemann, Urs Achim Following an approach of Matarrese and Pietroni, we derive the functional renormalization group (RG) flow of the effective action of cosmological large-scale structures.

 Fundamental partial compositeness / Sannino, Francesco ; Strumia, Alessandro ; Tesi, Andrea ; Vigiani, Elena We construct renormalizable Standard Model extensions, valid up to the Planck scale, that give a composite Higgs from a new fundamental strong force acting on fermions and scalars.

 The Higgs of the Higgs and the diphoton channel / Kannike, Kristjan ; Pelaggi, Giulio Maria ; Salvio, Alberto ; Strumia, Alessandro LHC results do not confirm conventional natural solutions to the Higgs mass hierarchy problem, motivating alternative interpretations where a hierarchically small weak scale is generated from a dimension-less quantum dynamics.
