Higgs I
- John Allison
Top Yukawa coupling is deeply connected to many fundamental puzzles in Higgs and Electroweak physics. In this study, we seek to measure the Top Yukawa coupling at the future high-energy muon colliders utilizing the Higgs unitarization in the $V_L V_L \rightarrow t\bar{t} $ process. If the Top Yukawa coupling
deviates from the Standard Model (SM) value, the amplitude of the
processes with...
We present simulation of the dominant off-shell Higgs production mechanisms (gluon fusion, vector boson fusion, and associated production with a vector boson) with subsequent decay to two Z bosons. Effects of Effective Field Theory (EFT) operators on kinematic distributions are modeled for the signal and interfering background diagrams.
In this presentation, I will explore the impact of finite top and bottom quark masses in the computation of scattering cross-sections for Higgs Boson production in association with three jets at Hadron Colliders like the CERN Large Hadron Collider. Additionally, I will offer insights into the expected outcomes for the production of a CP-violating Higgs.
We explore CP-violation in Higgs-top interactions via the semileptonic $pp \to t\bar{t}h$ channel with $h \to \gamma\gamma$ at the high luminosity LHC with machine learning-based unfolding techniques. We invert the event simulation chain, unfolding the detector-level events to construct and encode observables in their relevant partonic reference frame to improve CP sensitivity.
In this talk, we will discuss about the results of searches for Higgs pair production in the four-bottom-quark final state via gluon fusion (ggF), vector boson fusion (VBF) and the one associated with an additional vector boson (VHH) with the CMS detector. In addition to the analysis strategy and limits on the production cross section of this process, constraints on the Higgs boson...
