Jonathan Ferland is a PhD student from the University of Montreal, on the ATLAS experiment, on a three-month MCnet studentship in Durham.

The Standard Model (SM) of particle physics provides an excellent description of known particles and interactions up to the electroweak scale. However, the SM has some well-known deficiencies. For example, the Higgs boson, needed to explain the origin of masses, has never been observed. Even if it exists, the SM is unlikely to be valid at high energies because of hierarchy and fine tuning problems. The search for the explanation and description of electroweak symmetry breaking is certainly the main goal of the Large Hadron Collider (LHC) at CERN.

Many alternative scenarios to the Higgs mechanism have been suggested to generate mass, among them a class of models labelled as Technicolor models. These models assume the existence of new fermions enjoying additional strong interactions, leading to bound states (like, e.g. the technipion). This additional dynamics then explains the masses of the known particles, essentially by providing bound state degrees of freedom playing the role of the Higgs fields. Many variants of this class of models provide a rich phenomenology at future colliders, in many cases, however, the additional dynamics of the predicted particle states were at odds with experimental findings. This can in most cases be traced to the actual behaviour of the additional techni-interaction. Recently, a new model named Minimal Walking Technicolour has appeared, which replaces the fast running of the techni-interaction with a mild scale dependence only and which, due to its particle content, satisfies the experimental constraints. The MCNET project then consist in implementing this new model in Sherpa and briefly studying its phenomenology.
