Measurements of multi-differential cross sections for ttbar production at sqrt(s)=13 TeV with the CMS experiment
European School of High-Energy Physics, ESHEP2019, Saint PetersburgSaint Petersburg, Russian Federation, 4 Sep 2019 - 17 Sep 20192019-09-042019-09-17
We present our plans to measure multi-differential cross sections for top-pair (ttbar) production in pp collisions at sqrt(s)=13 TeV, using the full RUN II dataset recorded with the CMS detector.We perform the measurements with the dileptonic decay channel of the ttbar system, requiring two leptons of muon or electron type in the final state.With the data set of about 1 million events, nearly background free, we can study the distributions of kinematical and topological observables in the ttbar events in unprecedented detail and compare the results with the latest Standard Model based predictions.On the poster we will present the motivation for the measurement, the event selection steps, the kinematic reconstruction of the ttbar system and first control plots for the 2017 data set..

Copper molybdate (CuMoO4) has been intensively studied due to its diverse functional properties, including thermochromic, piezochromic, tribochromic, photoelectrochemical as well as catalytic and antibacterial. At room temperature and atmospheric pressure CuMoO4 exists in alpha phase with a bright green colour. [...]

Luminosity measurements at the CMS experiment
29th International Symposium on Lepton Photon Interactions at High Energies, LP2019, TorontoToronto, Canada, 5 Aug 2019 - 10 Aug 20192019-08-052019-08-10  GO
Precision luminosity calibration is critical to determine fundamental parameters of the standard model and to constrain or to discover beyond-the-standard-model phenomena at LHC. The luminosity determination at the LHC interaction point 5 with the CMS detector, using proton-proton collisions at 13 and 5.02 TeV during Run 2 of the LHC (2015–2018), is reported. [...]

Probing QCD using top quark pair production at $\sqrt{s} =$ 13 TeV in CMS
European Physical Society Conference on High Energy Physics, EPS-HEP2019, GhentGhent, Belgium, 10 Jul 2019 - 17 Jul 20192019-07-102019-07-17  GO
A measurement of the inclusive top quark-antiquark pair production cross section in proton proton collisions at a centre-of-mass energy of 13 TeV is used by the CMS experiment, together with the theoretical prediction at next-to-next-to-leading order, to determine the top quark mass and to extract a value of the strong coupling constant with different sets of parton distribution functions. Dilepton events are selected and the cross section is measured from a likelihood fit to the final state distributions. [...]

Exotic decay of the Higgs boson to a pair of light pseudoscalars in the CMS experiment
7th Conference of Large Hadron Collider Physics, LHCP2019, PueblaPuebla, Mexico, 20 May 2019 - 25 May 20192019-05-202019-05-25  GO
The Standard Model is one of the most successful theories at describing the strong, weak, and electromagnetic forces and the interactions between the elementary particles.The scalar boson discovered in 2012 at the Large Hadron Collider (LHC) might be consistent with the Higgs boson predicted by the Standard Model, thus validating the Higgs mechanism and therefore representing a further confirmation of this theoretical framework. However, the experimental data still leave plenty of room to determine whether or not an extension of the scalar sector is allowed.The LHC combination of the SM Higgs boson measurements at 7 and 8 TeV allows Higgs boson decays to BSM states with a rate of up to 34% at 95% confidence level.Presence of new physics within the context of the Two-Higgs-Double-Model and NMSSM theories allows the exotic decay of the Higgs boson into a pair of light pseudoscalars.

Search for additional Higgs bosons produced in association with b quarks and decaying into two b quarks
10th CERN Latin-American School of High-Energy Physics, CLASHEP2019, CordobaCordoba, Argentina, 13 Mar 2019 - 26 Mar 20192019-03-132019-03-26  GO
A huge breakthrough in particle physics was achieved with the discovery of the Higgs boson in 2012, which was followed by precision measurements of its properties. So far, the discovered particle is found to be in good agreement with the predictions of the Standard Model, but there is still sizable room for theories with extended Higgs sectors, like Supersymmetry or general Two Higgs Doublet Models.
