Natural Heavy Supersymmetry / Batell, Brian ; Giudice, Gian F ; McCullough, Matthew
We study how, as a result of the scanning of supersymmetry breaking during the cosmological evolution, a relaxation mechanism can naturally determine a hierarchy between the weak scale and the masses of supersymmetric particles. [...]

Two-Flavor Lattice QCD with a Finite Density of Heavy Quarks: Heavy-Dense Limit and "Particle-Hole" Symmetry / Rindlisbacher, Tobias ; de Forcrand, Philippe
We investigate the properties of the half-filling point in lattice QCD (LQCD), in particular the disappearance of the sign problem and the emergence of an apparent particle-hole symmetry, and try to understand where these properties come from by studying the heavy-dense fermion determinant and the corresponding strong-coupling partition function (which can be integrated analytically).

The Higgs-Yukawa model with higher dimension operators via EMFT / Akerlund, Oscar ; de Forcrand, Philippe
Using Extended Mean Field Theory (EMFT) on the lattice, we study properties of the Higgs-Yukawa model as an approximation of the Standard Model Higgs sector, and the effect of higher dimension operators. [...]

Prospects and status of quark mass renormalization in three-flavour QCD / Campos, I ; Fritzsch, P ; Pena, C ; Preti, D ; Ramos, A ; Vladikas, A
We present the current status of a revised strategy to compute the running of renormalized quark masses in QCD with three flavours of massless O(a) improved Wilson quarks. [...]

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 $M_t$. [...]
