The Higgs-gluon interaction is crucial for LHC phenomenology. To improve the constraints on the CP structure of this coupling, in this talk I will investigate Higgs production with two jets using machine learning. In particular, the CP sensitivity of the so far neglected phase space region that differs from the typical vector boson fusion-like kinematics is exploited. The presented results...
The CP structure of the Higgs boson is a fundamental Higgs property which has not yet been constrained with high precision.
CP violation in the Yukawa coupling between the Higgs boson and the top quark can be probed directly at the Large Hadron Collider by measuring top-quark-associated Higgs production. Multivariate analysis techniques are designed for a specific signal model and,...
Recently, a concept for a Hybrid Asymmetric Linear Higgs Factory (HALHF) has been proposed, where a center-of-mass energy of 250 GeV is reached by colliding a plasma-wakefield accelerated electron beam of 500 GeV with a conventionally accelerated positron beam of about 30 GeV. While clearly facing R&D challenges, this concept bears the potential to be significantly cheaper than any other...
Real singlet models are simple extensions of the SM as these models add
a new Higgs-like scalar that transforms as a singlet under the SM gauge
group. For the case of an additional particle that is heavier than twice
the SM-Higgs this scalar, labelled S, could play a role in
resonant-enhanced pp$\rightarrow$hh production. We here simulate samples for such
scenarios for the inclusive...
A measurement of the Higgs boson production via vector boson fusion (VBF) and its decay into a bottom quark-antiquark pair is presented using proton-proton collision data recorded by the CMS experiment at center-of mass energy of 13 TeV and corresponding to an integrated luminosity of 91/fb. Treating the gluon-gluon fusion process as a background and constraining its rate to the value expected...
The bottom anti-bottom Higgs boson decay channel of Higgs-associated top quark pair production offers direct access to measurements of the top Yukawa coupling and Higgs-$p_\mathrm{\kern0.1emT}$ differential cross-section, which are sensitive to potential new physics. To incorporate improvements such as developments in b-tagging and Monte Carlo simulation of the dominant $t\bar{t} + b\bar{b}$...
This talk will summarise a measurement of VH differential cross sections in $H\to b\bar{b}$ final state in Simplified Template Cross Section framework with CMS Run 2 data.
Measuring the Higgs self-coupling is a key target for future colliders and is enabled by double Higgs production. An important question is how the precision of this measurement improves with higher center-of-mass collision energy. In this work, we study the ZHH process at center-of-mass energies of 500, 550, and 600 GeV, simulated with the ILD detector concept from the International Linear...
