23 Jun 2010 | | Abstract: | The left-right twin Higgs(LRTH) model predicts the existence of three
additional Higgs bosons: one neutral Higgs $phi^{0}$ and a pair of charged
Higgs bosons $phi^{pm}$. In this paper, we studied the production of a pair
of charged and neutral Higgs bosons associated with standard model gauge boson
$Z$ at the ILC, i.e., $e^{+}e^{-}
ightarrow Zphi^{+}phi^{-}$ and
$e^{+}e^{-}
ightarrow Zphi^{0}phi^{0}$. We calculate the production rate and
present the distributions of the various observables, such as, the
distributions of the energy and the transverse momenta of final $Z$-boson and
charged Higgs boson $phi^{-}$, the differential cross section of the invariant
mass of charged Higgs bosons pair, the distribution of the angle between
charged Higgs bosons pair and the production angle distributions of $Z$-boson
and charged Higgs boson $phi^{-}$. Our numerical results show that, for the
process $e^{+}e^{-}
ightarrow Zphi^{+}phi^{-}$, the production rates are at
the level of $10^{-1} fb$ with reasonable parameter values. For the process of
$e^{+}e^{-}
ightarrow Zphi^{0}phi^{0}$, we find that the production cross
section are smaller than $6 imes 10^{-3} fb$ in most of parameter space.
However, the resonance production cross section can be significantly enhanced. | | Source: | arXiv, 1006.4589 | | Services: | Forum | Review | PDF | Favorites | |
