Lorentz violating quadratic gravity
R. B. Alfaia, Willian Carvalho, A. C. Lehum +3
In this paper, we explore the perturbative renormalization and study the classical dynamics of the bumblebee model coupled to quadratic gravity, a theoretical setting that allows t…

Complex bumblebee model
Willian Carvalho, A. C. Lehum, J. R. Nascimento +1
We formulate a renormalizable complex extension of the bumblebee theory in which the bumblebee field is promoted to a complex one and coupled to an Abelian gauge sector. Besides th…

Probing the flavour structure of dimension-6 EFT operators in multilepton final states in proton-proton collisions at = 13 TeV
CMS Collaboration
An analysis of the flavour structure of dimension-6 effective field theory (EFT) operators in multilepton final states is presented, focusing on the interactions of quarks with Z b…
