Orientador: Prof. Dr. José Kenichi Mizukoshi / Tese (doutorado) - Universidade Federal do ABC, Programa de Pós-Graduação em Física, 2016. / Searches for new physics beyond the Standard Model are important subjects at the current
Run-2 of the Large Hadron Collider (LHC) and next generation colliders. In this context,
we make independent studies of the phenomenology of a new hypothetical heavy Majorana
neutrino (N) and a heavy spin-1 charged vector (W¿) at the LHC and a future 100 TeV very
large hadron collider (VLHC), we also study the potential of the future International Linear
Collider (ILC) to measure the rare h !
Z Higgs decay. Toward this end, the N production
via the W
fusion process is investigated and found it to be larger than the Drell-Yan
production for mN > 1 TeV at the 14 TeV LHC and for mN > 770 GeV at the 100 TeV
VLHC. Then we computed the discovery potential of the these colliders to discover an N
using the same-sign dimuon channel. In the case of the h !
Z Higgs decay we investigated
the Higgsstrahlung production at the 250 GeV ILC, we found that a sensitivity of 58% can
be reached in the inclusive ¿Ê¿Ê
X channel with 3 ab.1, where X denotes the inclusive decay
of the Z boson from the Higgs. Finally, in the case of the W¿, we studied its contribution
to the h !
Higgs decay process and constrained the strength of the W¿W¿h interaction.
Finally, we study the Drell-Yan W¿ production with its decay to the Wh pair at the LHC.
