"Signals for Composite Higgs models in top/W/Z physics"
ABSTRACT:
In the first part of the seminar, I will briefly review how the idea of the Higgs boson being a composite particle of new strong dynamics can explain the hierarchy between the Planck and weak scales and how quarks and leptons being partially composite accounts for their basic structure as well. I will argue that the largest experimental signals for such a scenario arise in the top/W/Z sectors. Remarkably, this scenario might have a dual and more useful description in terms of a warped higher dimensional spacetime. So, in the second part of the seminar, I will focus on computing signals for such composite Higgs models at the upcoming Large Hadron Collider using the extra dimensional description. Specifically, I will consider detection of the excitations (called Kaluza-Klein modes) of the gluon and graviton in the extra dimension.
