The anomalous magnetic moment of muons has been a long-standing problem in SM. The current deviation of experimental value of the (g − 2) μ from the standard model prediction is exactly 4.2σ. Two Higgs Doublet Models can accommodate this discrepancy but such type of model naturally generate flavor changing neutral current(FCNC). To prevent this it was postulated that 2HDM without FCNC required...

We analyze in a model-independent way the potential to probe new physics using Higgs decay to ϒγ. The h→ϒγ decay width is unusually small in the Standard Model because of an accidental cancellation among the direct and indirect decay diagrams. Thus, any new physics that can modify the direct or the indirect decay amplitudes disrupts the accidental Standard Model cancellation and can...

We present the results of a search for a pseudoscalar higgs boson (A), where A decays to a Z boson and a Standard Model like higgs boson (h), using pp collision data collected by the CMS experiment during LHC Run-2 at centre-of-mass energy of 13 TeV. Such a pseudoscalar higgs boson can be produced and decay in various beyond SM models, such as 2HDM and MSSM etc. In the final states, we...

We study the Standard model (SM) Higgs production in association with a Z-boson at the LHC. The leading contribution comes from $q\bar{q}$-initiated (DY-like) subprocess. In addition to this, the gluon fusion subprocess via fermion loops also contributes to this process at higher orders in QCD. In this work, we study the impact of higher-order QCD corrections and provide precise results for...

The results of a search for Higgs boson pair (HH) production in the 4W, 2W2tau, and 4tau decay modes are presented. The search uses 138 /fb of proton-proton collision data recorded by the CMS experiment at the LHC at a center-of-mass energy of 13 TeV from 2016 to 2018. Analyzed events contain two, three, or four reconstructed leptons, including electrons, muons, and hadronically decaying tau...

The success of the LHC project is marked by not only the discovery of the Higgs boson a decade back, but also by the vast amount of knowledge acquired about the relevant physics. This talk will mainly highlight the major results on characterization of the Higgs boson based on the data from Run2 operation of the LHC.

Currently, the most important mandate of the LHC physics programme is to measure the self-coupling

At the LHC pair production of the Higgs boson provides direct access to $\lambda$, though the event rate
is extremely small in the standard model. However, contributions from new... -

An overview of the search for top quark associated Higgs boson production (ttH and tH) using full Run-2 proton-proton collision data (137 fb-1) collected by the CMS experiment at center-of-mass energy of 13 TeV will be presented. This will cover Higgs decays into final states involving pairs of photons as well as final states involving leptons (electrons, muons and taus). This search is...

Measurements of fiducial inclusive and differential cross sections of Higgs boson production in p-p collisions are presented based on the data collected with the CMS detector, corresponding to an integrated luminosity of 137 $fb^{-1}$ at a centre-of-mass energy of 13 TeV. The final state is considered where the Higgs boson decays to two W bosons, which subsequently decay to an electron, a...

Despite an extensive set of searches for physics beyond the standard model, no smoking-gun evidence of resonant phenomena is observed so far at the LHC. Nevertheless, the recent application of effective field theories (EFT) demonstrates that subtle deviations, hiding in the observables' distributions, can probe new physics at energy scales often exceeding the LHC's reach in the direct...
