一类双Higgs偶态模型中光标量的可行性及其衰变特征

Feasibility of light scalars in a class of two-Higgs-doublet models and their decay signatures

Gautam Bhattacharyya, Dipankar Das, Anirban Kundu

摘要:

我们证明,轻电荷和额外的中性标量在(100-200)GeV的质量范围内通过潜在的危险的味道约束在一个特定的类的两个希格斯偶极子模型,适当地抑制味道改变中性电流在树水平。我们研究了它们的衰变分支比到不同的费米子末态,并评论了它们在对撞机实验中被探测到的可能性。我们还评论如何他们的商标衰变签名可以用来区分他们从轻非标准标量预测在其他两个希格斯双重模型。

英文摘要:

We demonstrate that light charged and extra neutral scalars in the (100-200) GeV mass range pass the potentially dangerous flavor constraints in a particular class of two-Higgs-doublet model which has appropriately suppressed flavor-changing neutral currents at tree level. We study their decay branching ratios into various fermionic final states and comment on the possibility of their detection in the collider experiments. We also remark on how their trademark decay signatures can be used to discriminate them from the light nonstandard scalars predicted in other two-Higgs-doublet models.
