"Double Higgs production at the LHC"
This event is part of the HET Seminar Series.
In this talk, I will discuss how to probe new physics through double Higgs process at the LHC. In the first part, I will show that there is a strong correlation between the Higgs trilinear coupling and the nature of EWPT. Then I will discuss how to probe those non-SM values of the trilinear coupling by making use of the modifications in the invariant mass distribution. In the second part, I will show the possible modifications to the double Higgs production in the presence of a light stop and a modified top coupling. Because of the destructive interference of the triangle and the box diagram amplitude contributions to the double Higgs production, even a small modification in the top Yukawa coupling can lead to a significant increase of the double Higgs production rate.
