- Lingfeng Li (HKUST)
Studies of the CP properties of the Higgs boson in various production modes and decay channels are presented. Limits on the mixing of CP-even and CP-odd Higgs states are set by exploiting the properties of diverse final states.
Exotic decays of the Higgs boson are a well-motivated possibility, even with the discovery of a Higgs particle consistent with the SM, and they may provide the only window into BSM physics at the LHC. The Higgs boson can be used as a probe for new physics in many BSM scenarios, and this talk will cover the recent searches for exotic decays of the Higgs boson, using proton-proton collision data...
The discovery of the Higgs boson with the mass of about 125 GeV completed the particle content predicted by the Standard Model. Even though this model is well established and consistent with many measurements, it is not capable to solely explain some observations. Many extensions addressing this shortcoming introduce additional Higgs-like bosons which can be either neutral, singly-charged or...
One of the assumptions of simplified models is that there are a few new particles and interactions accessible at the LHC and all other new particles are heavy and decoupled. The effective field theory (EFT) method provides a consistent method to test this assumption. Simplified models can be augmented with higher order operators involving the new particles accessible at the LHC. Any UV...
The most precise measurements of Higgs boson cross sections, using the framework of Simplified Template Cross Sections (STXS), are obtained from a combination of the measurements performed in the different Higgs boson decay channels. These combined measurements, as well as those from single decay channels, are used to constrain those Standard Model Effective Field Theory (SMEFT) parameters...
In recent years there have been many proposals for new electron-positron colliders, such as the Circular Electron-Positron Collider, the International Linear Collider, and the Future Circular Collider in electron-positron mode. Much of the motivation for these colliders is precision measurements of the Higgs boson and searches for new electroweak states. In this talk, we propose a new search...
With the full Run 2 pp collision dataset collected at 13 TeV, very detailed measurements of Higgs boson properties can be performed. This talk presents measurements of Higgs boson properties using decays into bosons, including production mode cross sections and simplified template cross sections, as well as their interpretations.
In the recent years, several measurements of $B$-decays with flavor changing neutral currents, i.e. $b\to s$ transitions hint at deviations from the Standard Model (SM) predictions.These decays are forbidden at tree-level in the SM and can only proceed via suppressed loop level diagrams. Rare decays of $B$ mesons are an ideal probe to search for phenomena beyond the SM, since contributions...
