Production of multiple charged Higgs bosons in 3-3-1 models | | R. Martinez

20 Aug 2012 | | Abstract: | We undertake the study of the charged Higgs bosons predicted by the model
with gauge symmetry $SU(3)_c otimes SU(3)_L otimes U(1)_X$. By considering
Yukawa mixing couplings between small ($sim$ GeV) and large ($sim$ TeV)
scales, we show that the hypercharge-one $H_1^{pm}$ and hypercharge-two
$H_2^{pm}$ Higgs bosons predicted by the model, can be simultaneously produced
in $pp$ collisions at different production rates. At low energy, the
$H_1^{pm}$ bosons exhibit the same properties as the charged Higgs bosons from
a two Higgs doublet model (2HDM), while $H_2^{pm}$ are additional like-charged
Higgs bosons from the underlying 3-3-1 model. Thus, the identification of
multiple like-charged Higgs boson resonances may test the compatibility of
theoretical models with experimental data. We study $H_{1,2}^{pm}$ pair and
associated $tbH_{1,2}^{pm}$ productions at CERN LHC collider. In particular,
we obtain that pair production can be as large as the single production in
gluon-gluon collisions due to the interchange of a heavy neutral $Z’$ gauge
boson predicted by the model. By considering decays to leptons $H_{1,2}^{pm}
ightarrow au
u_{ au}$, we obtain scenarios where small peaks of
$H_{2}^{pm}$-boson events in transverse mass distributions can be identified
over the $H_{1}^{pm}$ background. | | Source: | arXiv, 1208.4085 | | Services: | Forum | Review | PDF | Favorites | |
