  With the discovery of a Higgs-like particle in 2012, attention has now turned
to measuring its properties, e.g., coupling to various bosonic and fermionic
final states, its spin and parity, etc. In this note, we study the sensitivity
of experiments at the LHC to its coupling to the top quark, by searching for
the process pp $\rightarrow t\bar{t}H$, where the primary decay mode of the $H$
is $\rightarrow b\bar{b}$. In this paper, the $t\bar{t}$ system is detected in
the dilepton final state. This study is performed assuming a center of mass
energy of 14 TeV and integrated luminosities of 300 fb$^{-1}$ (with an average
pileup ($\mu$) of 50 additional collisions per bunch crossing) and 3000
fb$^{-1}$ (with $\mu=140$). We include systematic uncertainties in production
cross-sections as well as the more important experimental uncertainties.
Preliminary studies indicate that we will observe the $t\bar{t}H$ final state
with a significance of 2.4 and $\ge 5.3$ for the two luminosity scenarios,
respectively; addition of other $t\bar{t}$ final states should increase the
overall significance for observing $t\bar{t}H$.
