Continuum limit and universality of the Columbia plot / de Forcrand, Philippe (ETH, Zurich (main) ; CERN) ; D'Elia, Massimo (INFN, Pisa ; Pisa U.)
Results on the thermal transition of QCD with 3 degenerate flavors, in the lower-left corner of the Columbia plot, are puzzling. [...]

A Worm Algorithm for the Lattice CP(N-1) Model / Rindlisbacher, Tobias (Zurich, ETH) ; de Forcrand, Philippe (Zurich, ETH ; CERN)
The CP(N-1) model in 2D is an interesting toy model for 4D QCD as it possesses confinement, asymptotic freedom and a non-trivial vacuum structure. [...]

Dark Matter "Transporting" Mechanism Explaining Positron Excesses / Kim, Doojin (CERN) ; Park, Jong-Chul (Chungnam Natl. U.) ; Shin, Seodong (Yonsei U.)
We propose a novel mechanism to explain the positron excesses, which are observed by satellite-based telescopes including PAMELA and AMS-02, in dark matter (DM) scenarios. [...]

On the Octonionic Self Duality equations of 3-brane Instantons / Floratos, Emmanuel (Democritos Nucl. Res. Ctr. ; Athens, U. ; CERN) ; Leontaris, George K. (CERN ; Ioannina U.)
We study the octonionic selfduality equations for $p=3$-branes in the light cone gauge and we construct explicitly, instanton solutions for spherical and toroidal topologies in various flat spacetime dimensions $(D=5+1,7+1,8+1,9+1)$, extending previous results for $p=2$ membranes. [...]

Topics in Higgs Physics / Ellis, John (King's Coll. London ; CERN)
These lecture notes review the theoretical background to the Higgs boson, provide an introduction to its phenomenology, and describe the experimental tests that lead us to think that "beyond any reasonable doubt, it is a Higgs boson". [...]

Linearized supergravity with a dynamical preferred frame / Marakulin, Arthur (Moscow, INR) ; Sibiryakov, Sergey (Moscow, INR ; CERN ; Ecole Polytechnique, Lausanne)
We study supersymmetric extension of the Einstein-aether gravitational model where local Lorentz invariance is broken down to the subgroup of spatial rotations by a vacuum expectation value of a timelike vector field. [...]

Supersymmetric extensions of the standard model contain additional heavy neutral Higgs bosons that are coupled to heavy scalar top quarks (stops). [...]

We investigate the scalar and pseudoscalar spectrum of the $SU(2)$ gauge theory with $N_f=2$ flavours of fermions in the fundamental representation using non perturbative lattice simulations. [...]
