Observable Effects of General New Scalar Particles
Jorge de Blas, Mikael Chala, Manuel Perez-Victoria +1
We classify all possible new scalar particles that can have renormalizable linear couplings to Standard Model fields and therefore be singly produced at colliders. We show that thi…
Collider limits on leptophilic interactions
Francisco del Aguila, Mikael Chala, Jose Santiago +1
Leptophilic interactions can only be observed at the LHC in four-lepton final states. If these interactions are mediated by a resonance in the di-leptonic channel with renormalizab…
The Elusive Gluon
Mikael Chala, Jose Juknevich, Gilad Perez +1
We study the phenomenology of vector resonances in the context of natural composite Higgs models. A mild hierarchy between the fermionic partners and the vector resonances can be e…
From Tevatron's top and lepton-based asymmetries to the LHC
Adrian Carmona, Mikael Chala, Adam Falkowski +4
We define a lepton-based asymmetry in semi-leptonic ttbar production at the LHC. We show that the ratio of this lepton-based asymmetry and the ttbar charge asymmetry, measured as a…
