We investigate chiral Higgs-Yukawa models with a non-abelian gauged left-handed sector reminiscent to a sub-sector of the standard model. We discover a new weak-coupling fixed-point behavior that allows for ultraviolet complete RG trajectories which can be connected with a conventional long-range infrared behavior in the Higgs phase. Despite the weak coupling properties, the system exhibits...

We construct lattice action for three-dimensional N=4 supersymmetric gauge theory with matter fields in the fundamental representation. We also discuss the construction of N=4 U(N_1)xU(N_2) quiver lattice gauge theory with bi-fundamental matter fields. Some issues such as flat directions, fine tuning and sign problem appearing in these theories are also briefly discussed.

Precision calculations for hadron colliders require numerous computational methods, among others the simulation of parton showers. They provide a good description of collinear radiation, i.e. the internal structure of jets. However, to better describe the production of jets, NLO matrix elements are needed. Their interface to parton showers involves problem, leading to the loss of NLO accuracy....

Composite Higgs models represent an attractive extension of the Standard Model of particle physics, providing a solution to the hierarchy problem. The Higgs-like particle is realized as a bound state of a strongly coupled sector. This implies the existence of further bound states at the TeV scale, which can be searched for at the LHC. In this talk we focus on the composite quark partners, i.e....
