LHC signals of radiatively-induced neutrino masses and implications for the Zee-Babu model
Julien Alcaide, Mikael Chala, Arcadi Santamaria
Contrary to the see-saw models, extended Higgs sectors leading to radiatively-induced neutrino masses do require the extra particles to be at the TeV scale. However, these new stat…
Direct Bounds on Heavy Top-Like Quarks With Standard and Exotic Decays
Mikael Chala
Heavy vector-like quarks with electric charge (also called \textit{heavy tops}) appear naturally in many extensions of the Standard Model. Although these typically predict…
Exceptional Composite Dark Matter
Guillermo Ballesteros, Adrian Carmona, Mikael Chala
We study the dark matter phenomenology of non-minimal composite Higgs models with broken to the exceptional group . In addition to the Higgs, three pseudo-Nambu-Goldst…
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…
A light sneutrino rescues the light stop
Mikael Chala, Antonio Delgado, Germano Nardini +1
Stop searches in supersymmetric frameworks with -parity conservation usually assume the lightest neutralino to be the lightest supersymmetric particle. In this paper we consider…
