Indirect determinations of the top quark mass / Giudice, Gian F ; Paradisi, Paride ; Strumia, Alessandro
We give a complete analysis of indirect determinations of the top quark mass in the Standard Model by introducing a systematic procedure to identify observables that receive quantum corrections enhanced by powers of $M_t$. [...]

Symanzik improvement of the gradient flow in lattice gauge theories / Ramos, A ; Sint, S
We apply the Symanzik improvement programme to the 4+1-dimensional local re-formulation of the gradient flow in pure $SU(N)$ lattice gauge theories. [...]

Simplified dark matter top-quark interactions at the LHC / Haisch, Ulrich ; Re, Emanuele
Stringent limits on the interactions between dark matter (DM) and the standard model can be set by studying how initial-state or final-state particles recoil against missing transverse energy (MET). [...]

Neutron star structure from QCD / Fraga, Eduardo S ; Kurkela, Aleksi ; Vuorinen, Aleksi
In this review article, we argue that our current understanding of the thermodynamic properties of cold QCD matter, originating from first principles calculations at high and low densities, can be used to efficiently constrain the macroscopic properties of neutron stars. [...]

On a Canonical Quantization of 3D Anti de Sitter Pure Gravity / Kim, Jihun ; Porrati, Massimo
We perform a canonical quantization of pure gravity on AdS3 using as a technical tool its equivalence at the classical level with a Chern-Simons theory with gauge group SL(2,R)xSL(2,R). [...]

Higgs-bosons couplings to quarks and leptons in the supersymmetric Standard Model with a gauge singlet / Crivellin, Andreas ; Yamada, Youichi
The loop corrections to the couplings of Higgs bosons to quarks and charged leptons are calculated within supersymmetric versions of the Standard Model, extended by a gauge singlet. [...]

Fiducial cross sections for Higgs boson production in association with a jet at next-to-next-to-leading order in QCD / Caola, Fabrizio ; Melnikov, Kirill ; Schulze, Markus
We extend the recent computation of Higgs boson production in association with a jet through next-to-next-to-leading order in perturbative QCD by including decays of the Higgs boson to electroweak vector bosons. [...]

Probing the Moduli Dependence of Refined Topological Amplitudes / Antoniadis, Ignatios ; Florakis, Ioannis ; Hohenegger, Stefan ; Narain, K S ; Assi, Ahmad Zein
With the aim of providing a worldsheet description of the refined topological string, we continue the study of a particular class of higher derivative couplings $F_{g,n}$ in the type II string effective action compactified on a Calabi-Yau threefold. [...]

Supersymmetric Dark Matter after LHC Run 1 / Bagnaschi, E A ; Buchmueller, O ; Cavanaugh, R ; Citron, M ; De Roeck, A ; Dolan, M J ; Ellis, J R ; Flaecher, H ; Heinemeyer, S ; Isidori, G et al.
Different mechanisms operate in various regions of the MSSM parameter space to bring the relic density of the lightest neutralino, neutralino_1, assumed here to be the LSP and thus the Dark Matter (DM) particle, into the range allowed by astrophysics and cosmology. [...]
