摘要:

我们提出了一个单圈修正的希格斯玻色子质量的MSSM与非最小的味道违反。味道违反是从夸克质量矩阵中的一般味道混合的假设产生的,并且这些由一组完整的delta^XY_ij(X,Y = L,R; i; j = t,c,u或b,s,d)参数化。我们根据这些Δ ^XY_ij计算对希格斯质量的修正,同时考虑到B物理数据的所有相关限制。这包括来自BR(B -> Xs γ)、BR(Bs -> mu+ mu-)和Δ M_B_s的约束。在考虑了这些约束条件后,我们发现对希格斯玻色子玻色子质量的修正相当大,在最轻的MSSM希格斯玻色子玻色子质量超过几十GeV的情况下。这些修正主要是针对低tan β的情况。在测量希格斯玻色子质量的情况下,这些修正可以用来对Δ XY_ij设置进一步的约束。

英文摘要:

We present one-loop corrections to the Higgs boson masses in the MSSM with Non-Minimal Flavor Violation. The flavor violation is generated from the hypothesis of general flavor mixing in the squark mass matrices, and these are parameterized by a complete set of delta^XY_ij (X, Y = L,R; i; j = t, c, u or b, s, d). We calculate the corrections to the Higgs masses in terms of these delta^XY_ij taking into account all relevant restrictions from B-physics data. This includes constraints from BR(B -> Xs gamma), BR(Bs -> mu+ mu-) and delta M_B_s . After taking into account these constraints we find sizable corrections to the Higgs boson masses, in the case of the lightest MSSM Higgs boson mass exceeding tens of GeV. These corrections are found mainly for the low tan beta case. In the case of a Higgs boson mass measurement these corrections might be used to set further constraints on delta^XY_ij.
