On the Importance of Three-Body Decays of Vector-Like Quarks
Carlos Bautista, Leonardo de Lima, Ricardo D. Matheus +1
It is a common feature of vector-like extensions of the electroweak sector to have near degenerate states, such as electroweak doublets. In simplified models, it is usually assumed…
Probing the Top-Higgs Sector with Composite Higgs Models at Present and Future Hadron Colliders
Carlos Bautista, Leonardo de Lima, Ricardo D. Matheus +3
We study the production of and at hadron colliders, in the minimal Composite Higgs Models, based on the coset . We explore the fermionic rep…
A warped relaxion
Nayara Fonseca, Benedict von Harling, Leonardo de Lima +1
We construct a UV completion of the relaxion in a warped extra dimension. We identify the relaxion with the zero mode of the fifth component of a bulk gauge field and show how hier…
Minimally extended SILH
Mikael Chala, Gauthier Durieux, Christophe Grojean +2
Higgs boson compositeness is a phenomenologically viable scenario addressing the hierarchy problem. In minimal models, the Higgs boson is the only degree of freedom of the strong s…
N-Relaxion: Large Field Excursions from a Few Site Relaxion Model
Nayara Fonseca, Leonardo de Lima, Camila S. Machado +1
Relaxion models are an interesting new avenue to explain the radiative stability of the Standard Model scalar sector. They require very large field excursions, which are difficult…
Higgs Flavor Violation as a Signal to Discriminate Models
Leonardo de Lima, Camila S. Machado, Ricardo D. Matheus +1
We consider the Higgs Lepton Flavor Violating process , in which CMS found a excess of events, from a model independent perspective, and find that it is d…
Colorless Top Partners, a 125 GeV Higgs, and the Limits on Naturalness
Gustavo Burdman, Zackaria Chacko, Roni Harnik +2
Theories of physics beyond the Standard Model that address the hierarchy problem generally involve top partners, new particles that cancel the quadratic divergences associated with…
Full-hierarchy Quiver Theories of Electroweak Symmetry Breaking and Fermion Masses
Gustavo Burdman, Nayara Fonseca, Leonardo de Lima
We consider quiver theories in four dimensions with a large ultra-violet cutoff. These theories require that an ordered set of vacuum expectation values for the link fields develop…
