The Electroweak Phase Transition in Nearly Conformal Technicolor

Understand

We examine the temperature-dependent electroweak phase transition in extensions of the Standard Model in which the electroweak symmetry is spontaneously broken via strongly coupled, nearly-conformal dynamics.

• In particular, we focus on the low energy effective theory used to describe Minimal Walking Technicolor at the phase transition.
• Using the one-loop effective potential with ring improvement, we identify significant regions of parameter space which yield a sufficiently strong first order transition for electroweak baryogenesis.
• The composite particle spectrum corresponding to these regions can be produced and studied at the Large Hadron Collider experiment.
