Testing the couplings of the Higgs boson to quarks is important to understand the origin of quark masses. The talk presents Simplified Template Cross Section measurements for Higgs boson production in association with a vector boson using decays to two b quarks using pp collision data collected at 13 TeV, along with an interpretation in an Effective Field Theory framework. A search for...
We present the latest CMS results on the measurement of Higgs boson production with H->bb decays, considering production in association with a vector boson and via vector boson fusion or gluon fusion. In addition, we discuss the latest searches for H->cc decays.
Searches for Higgs boson decays to two second-generation quarks or leptons, based on 13 TeV pp collision data, are presented, as well as indirect constraint of the Yukawa coupling of the Higgs boson to the charm quark.
The latest results are presented for rare decays of the Higgs boson (H->ee, H->mumu, H->Zg, ...), using the Run-2 data set collected by the CMS experiment.
The Standard Model predicts several rare Higgs boson decay channels, among which are decays to a Z boson and a photon, H to Zgamma, and to a low-mass lepton pair and a photon H to llgamma. The observation of these decays could open the possibility of studying the CP and coupling properties of the Higgs boson in a complementary way to other analyses. In addition, lepton-flavor-violating decays...
Experimentally probing the charm-Yukawa coupling in the LHC experiments
is important, but very challenging due to an enormous QCD background. We study a new channel that can be used to search for the Higgs decay $H\to c\bar c$, using the vector boson fusion (VBF) mechanism with an associated photon. In addition to suppressing the QCD background, the photon gives an effective trigger handle....
We present recent measurements of ttH production with the full run 2 dataset, including measurements of CP properties of the Higgs boson.
The measurement of Higgs boson production in association with one or two top quarks is essential to understand the top-quark couplings to the Higgs boson. This talk presents the analyses using Higgs boson into several final states, using pp collision data collected at 13 TeV.
The associated production of a $b\bar{b}$ pair with a Higgs boson could provide an important probe to both the size and the phase of the bottom-quark Yukawa coupling, $y_b$. However, the signal is shrouded by several background processes including the irreducible $Zh, Z\to b\bar{b}$ background. We show that the analysis of kinematic shapes provides us with a concrete prescription for...
The standard model (SM) predicts the Higgs boson to be even under charge-parity (CP) inversion. That makes any experimentally observed deviations from this hypothesis an intriguing hint towards new physics.
In this talk we present the first measurement of the CP properties of the Higgs boson in its coupling to leptons. In particular, the decay into a pair of tau leptons preserves CP...
With the discovery of the Higgs boson at the CERN Large Hadron Collider (LHC), the particle spectrum of the Standard Model (SM) is complete. The next target at the energy frontier will be to study the Higgs properties and to search for the next scale beyond the SM. Experimentally, the $H\to c \bar{c}$ channel would be extremely difficult to dig out because of both the weak Yukawa coupling and...
We explore the direct Higgs-top CP structure via the $pp \to t\bar{t}h$ channel with machine learning techniques, considering the clean $h \to \gamma\gamma$ final state at the high luminosity LHC~(HL-LHC). We show that a combination of a comprehensive set of observables, that include the $t\bar{t}$ spin-correlations, with mass minimization strategies to reconstruct the $t\bar{t}$ rest frame...
