英文摘要	In the framework of the simplest little Higgs model (SLHM), we study the production of a pair of neutral CP-even Higgs bosons at the LHC. First, we examine the production rate and find that it can be significantly larger than the SM prediction. Then we investigate the decays of the Higgs-pair and find that for a low Higgs mass their dominant decay mode is hh -> eta eta eta eta (eta is a CP-odd scalar) while hh -> b (b) over bar eta eta and hh -> eta eta WW may also have sizable ratios. Finally, we comparatively study the rates of pp -> hh -> b (b) over bar tau(+)tau(-), pp -> hh -> b (b) over bar gamma gamma, and pp -> hh -> WWWW in the SLHM and the littlest Higgs models (LHT). We find that for a light Higgs, compared with the SM predictions, all the three rates can be sizably enhanced in the LHT but severely suppressed in the SLHM; while for an intermediately heavy Higgs, both the LHT and SLHM can enhance sizably the SM predictions.
