Crossing into the Region for Leptophilic ALPs
Marta F. Zamoro, Ãlvaro Lozano-Onrubia, Álvaro Lozano-Onrubia +2
Axion-like particles (ALPs) are typically identified as pseudoscalars whose couplings are shift-symmetry invariant with the exception of their couplings to gauge bosons and their m…

V-Associated Production & Vector Boson Fusion as an LHC Signature of CP Violation
Rodrigo Capucha, Ãlvaro Lozano-Onrubia, Luca Merlo +2
We investigate the role of vector boson fusion (VBF) and associated production with an electroweak boson (V-AP) of beyond-the-Standard-Model Higgses at the LHC in probing CP violat…

Early Universe hypercharge breaking and neutrino mass generation
Sergio López-Zurdo, Ãlvaro Lozano-Onrubia, Luca Merlo +1
We show that the conditions allowing for a spontaneous breaking of the hypercharge gauge symmetry of the Standard Model (SM) in the early Universe are generically present…
