We propose the signal $1b+1l+N_j+\etslash$ along with appropriate selectioncriteria for the LHC 7 TeV run, where the number of jets $(N_j)$ is $\ge$ 2 or4. These signals can complement the canonical $Jets + \etslash$ signature sincethey are sensitive to the trilinear soft breaking parameter $(A_0)$ and lowvalues of the parameter tan$\beta$ in the minimal supergravity (mSUGRA) model.A large region of this mSUGRA parameter space within the reach of the ongoingexperiments at the LHC is disfavoured by the bound on the lightest Higgs bosonmass ($m_h \ge 114.4 $ GeV) unless $A_0$ has moderate to large negative values.Interestingly this parameter space with $A_0 \ne 0$ is also consistent with theobserved dark matter relic density. A natural consequence of large $A_0$ is theexistence of a light top squark ($\lstop$). The proposed signals primarily stemfrom direct $\lstop \lstop^*$ production and/or $\tilde g \ra \tilde t_{1} t $,if all squark-gluino events are considered. A thorough analysis of the signalsand the corresponding backgrounds are presented using the event generatorPythia. We finally compare the signal size for $A_0 = 0$ and $A_0 \ne 0$.
