Based on the analysis of 5 fb^{−1} of data at the LHC, the ATLAS and CMS collaborations have presented evidence for a Higgs boson with a mass in the 125 GeV range. We consider the 125 GeV neutral Higgs pair production process in the context of largeextradimensions (LED) model including the KaluzaKlein (KK) excited gravitons at the LHC. We take into account the LED effects coming from gluongluon fusion and quarkantiquark collision channels as well as their corresponding nexttoleading order (NLO) QCD loop induced corrections. We analyse their impacts on both the total cross section and some key distributions. Indeed, pp → HH has the clear advantage of a lower standard model (SM) background compare to process like pp → jj, though its SM prediction is very small, it is shown that the LED model raises the cross section of Higgs pair production compare to its SM prediction and enhance the transverse momentum \( \left( {p_T^H} \right) \) and invariant mass (M _{ HH }) distributions especially at high scales of \( p_T^H \) and M _{ HH }. By including the NLO QCD loop corrections, the scale dependence of total cross section can be reduced obviously. Choose suitable decay modes like \( H\,H\to b\overline{b}\gamma \gamma \) or \( H\,H\to b\overline{b}{\mu^{}}{\mu^{+}} \) and some simple cuts, we can strongly reduce the SM background but keep most of the LED effects, leading Higgs pair production a promising channel to search LED effects.
