Particle Theory Seminar: Electroweak skyrmions in the HEFT - Juan Criado, Durham

1:30 pm VIA ZOOM

Electroweak skyrmions in the HEFT.

Skyrmions are energetically stable static field configurations, initially proposed to describe baryons as topological solitons in an effective field theory of mesons. In this talk, we will see how they arise in the electroweak sector. A powerful tool for studying skyrmions, with applications in many other non-perturbative problems, are neural networks. We will discuss their use in computing the skyrmion solutions and the shape of the energy functional. This allows to find which effective operators can stabilize them. Finally, we will consider some phenomenological aspects of skyrmions: the collider signatures of their stabilizing operators, and their potential as Dark Matter candidates.
