2. Constraining SMEFT operators $\mathcal{O}_{tZ}$ and $\mathcal{O}_{tW}$ via searches in $tZj$ and $t\bar{t}Z$ channels with Machine Learning

We explore the projected sensitivity for Standard Model Effective Field Theory (SMEFT) coefficients $\mathcal{C}_{tZ}$ and $\mathcal{C}_{tW}$ via associated single top production $ pp \to tZj$ and top pair production $pp \to t\bar{t}Z$ channels with machine learning techniques, at the high luminosity LHC (HL-LHC). Implications from new physics modifications in relevant background processes are...

17. Toponium at the LHC

Measurements of the di-leptonic top-antitop events at the LHC unraveled some excesses. We examine the possibility that those excesses can be consequences of non-perturbative enhancement of the production cross section near the t-tbar threshold. While sub-dominant in terms of total rates, so-far neglected toponium effects yield the additional production of di-leptonic systems with small...

4. NLO Multijet Merging for Higgs Production

Mr Tinghua Chen (Wichita State University)

The discovery of the Higgs boson in 2012 by ATLAS and CMS Collaborations opens a new era to particle physics, making processes involving Higgs production interesting and essential in many ways. For the first time, we have presented complete results at NLO prediction for electroweak Higgs production merged with dipole shower by unitarized merging algorithm framework in Herwig 7 and compared to...
