The kinetics of domain growth and aging in conserved order parameter systems,in the presence of short-range interaction, is widely studied. Due to technicaldifficulties and lack of resources, regarding computation, the dynamics isstill not well established in the cases where long-range interactions areinvolved. Here we present related results from the Monte Carlo simulations ofthe two-dimensional long-range Ising model (LRIM). Random initialconfigurations, for $50:50$ compositions of up and down spins, mimicking hightemperature equilibrium states, have been quenched to temperatures inside thecoexistence curve. Our analysis of the simulation data, for such a protocol,shows interesting dependence of the aging exponent, $\lambda$, on $\sigma$, theparameter, within the Hamiltonian, that controls the range of interaction. Tocomplement these results, we also discuss simulation outcomes for the growthexponent. The obtained values of $\lambda$ are compared with a well-knownresult for the lower bounds. For this purpose we have extracted interestingproperties of the evolving structure.
