The mass of the Higgs boson can be measured in the Higgs to four leptons and Higgs to two photons decay channels, where the excellent mass resolution can be used to reconstruct the Higgs boson invariant mass. The same decays can be used to measure the Higgs boson natural width, either by exploiting the offshell Higgs contribution to the four leptons and two leptons plus two neutrinos...
The latest measurement of the Higgs mass in the 4l final state at CMS will be presented. The prospects with the HL-LHC on the Higgs mass sensitivity will also be shown.
With the full Run 2 pp collision dataset collected at 13 TeV, very detailed measurements of Higgs boson coupling and kinematical properties can be performed, exploiting a variety of final states and production modes, probing different regions of the phase space with increasing precision. Coupling, fiducial and differential measurements can then be combined to exploit the specific strength of...
The most recent fiducial differential cross section measurements performed in the $\mathrm{H}\rightarrow{\rm Z}{\rm Z}\rightarrow4\ell$ ($\ell={\rm e},\mu$) decay channel are presented. The results have been obtained using data collected by the CMS experiment, corresponding to an integrated luminosity of 138 fb-1 at a centre of mass energy of 13 TeV. The fiducial cross section is measured with...
The VBF production mode has the 2nd largest production cross section for Higgs bosons in the SM at the LHC, and provides a way to study the Higgs boson's interactions with vector bosons. In this talk, recent measurements of the VBF Higgs boson production mode at CMS will be discussed. All measurements make use of data collected during Run 2 of the LHC.
This talk will present a measurement of the charge conjugation and parity ($CP$) properties in the Higgs boson interaction with $\tau$ leptons. The Yukawa interaction is generalized with a single mixing angle parameter $\phi_{\tau}$ to describe $CP$-odd interactions between the Higgs boson and $\tau$ leptons. The study is based on a measurement of $CP$-sensitive angular observables defined by...
Recent years have seen an unprecedented development of techniques devoted to identifying jets from the hadronization of heavy flavor quarks. This was made possible by the extensive usage of modern machine learning techniques. In particular, the identification of heavy resonance final states involving a pair of bottom or charm quarks largely benefited from these developments. In addition,...
This talk will present the latest CMS results on the measurement of Higgs boson production with H->bb decays. It will consider the Higgs boson production via gluon fusion in the boosted topology (ggF Hbb), via vector boson fusion (VBF Hbb), in association with a vector boson (VH Hbb), and with a top quark pair (ttHbb). In addition, the talk will discuss the latest results of the search for the...
The measurement of the H->bbbar decay rate by ATLAS and CMS offers an opportunity to test the scale evolution or "running" of the bottom quark mass. With an excellent mass sensitivity, reduced dependence on alpha_s and a clearly identifiable scale, the Higgs decay process is the ideal laboratory to extract a high-scale quark mass. The mass at the scale given by the Higgs boson mass, mb(mH) is...
Many physics analyses using the CMS detector at the LHC require accurate, high resolution electron and photon energy measurements. Excellent energy resolution is crucial for studies of Higgs boson decays with electromagnetic particles in the final state, as well as searches for very high mass resonances decaying to energetic photons or electrons. The CMS electromagnetic calorimeter (ECAL) is a...
