标题： On the radiative corrections to the neutral Higgs boson masses in the NMSSM

摘要： 我们提供了NMSSM中中性希格斯玻色子自能和真空期望值的完整一环计算。 此外，我们在有效势近似下计算了中性希格斯玻色子质量的两环O(alpha_t*alpha_s+alpha_b*alpha_s)修正。 与之前计算相比，新计算的修正可以解释轻标量和赝标量质量几GeV的改变，并且它们也可以显著影响单态和MSSM类希格斯标量之间的混合。 考虑这些修正对于MSSM和NMSSM在希格斯场方面的预测进行有意义的比较将是至关重要的。 显示英文摘要

摘要： We provide a full one-loop calculation of the self energies and tadpoles of the neutral Higgs bosons of the NMSSM. In addition, we compute the two-loop O(alpha_t*alpha_s+alpha_b*alpha_s) corrections to the neutral Higgs boson masses in the effective potential approximation. With respect to earlier calculations, the newly-computed corrections can account for shifts of a few GeV in the light scalar and pseudoscalar masses, and they can also sizeably affect the mixing between singlet and MSSM-like Higgs scalars. Taking these corrections into account will be crucial for a meaningful comparison between the MSSM and NMSSM predictions for the Higgs sector.
