Tricking Landau-Yang: How to obtain the diphoton excess from a vector resonance
Mikael Chala, Michael Duerr, Felix Kahlhoefer +1
We show that contrary to naive expectations the recently observed diphoton excess can be explained by a vector resonance, which decays to a photon and a light scalar , followed…
Renormalization Group Constraints on New Top Interactions from Electroweak Precision Data
Jorge de Blas, Mikael Chala, Jose Santiago
Anomalous interactions involving the top quark contribute to some of the most difficult observables to directly access experimentally. They can give however a sizeable correction t…
Composite Dark Sectors
Adrian Carmona, Mikael Chala
We introduce a new paradigm in Composite Dark Sectors, where the full Standard Model (including the Higgs boson) is extended with a strongly-interacting composite sector with globa…
Four and two-lepton signals of leptophilic gauge interactions at large colliders
Francisco del Aguila, Mikael Chala, Jose Santiago +1
Many Standard Model extensions can contribute to four-lepton signals at large colliders. We review the particular case of leptophilic interactions eventually observable at the LHC…
Constraining Dark Sectors with Monojets and Dijets
Mikael Chala, Felix Kahlhoefer, Matthew McCullough +2
We consider dark sector particles (DSPs) that obtain sizeable interactions with Standard Model fermions from a new mediator. While these particles can avoid observation in direct d…
