Can a Nonstandard Invisible Pair Mimic the Michel Distribution?
Pablo Roig
The paper investigates whether the standard Michel distribution observed in lepton decays could be reproduced by an invisible sector, finding that only a massless complex scalar pa…

Prospects for detecting the rare heavy Higgs decay through the channel at the LHC
M. A. Arroyo-Ureña, Alejandro Ibarra, Pablo Roig +1
We study the decay of a heavy CP-even neutral Higgs into an on-shell Standard Model-like Higgs boson and two photons, , in the two-Higgs doublet model. We argue that th…
