MSSM中轻Higgs质量的三圈预言

Three-Loop Predictions for the Light Higgs Mass in the MSSM

Philipp Kant

摘要:

标准模型的最小超对称扩展(MSSM)以一个轻的希格斯玻色子玻色子为特征,其质量Mh由理论预测。考虑到大型强子对撞机将能够非常精确地测量轻希格斯粒子的质量,对Mh的精确理论计算是对MSSM的重要检验。为了达到这样的精度,我们提出了O(alpha_t*alpha_s^2)的三圈辐射修正,并提供了一个计算机代码,将我们的结果与文献中可用的较低圈阶Mh的修正相结合。

英文摘要:

The Minimal Supersymmetric Extension of the Standard Model (MSSM) features a light Higgs boson, the mass Mh of which is predicted by the theory. Given that the LHC will be able to measure the mass of a light Higgs with great accuracy, a precise theoretical calculation of Mh yields an important test of the MSSM. In order to deliver this precision, we present three-loop radiative corrections of O(alpha_t*alpha_s^2) and provide a computer code that combines our results with corrections to Mh at lower loop orders that are available in the literature.
