Measurement of B meson production fraction ratios in proton-proton collisions at $\sqrt{s}$ = 13 TeV using open-charm and charmonium decays
Aram Hayrapetyan, Vladimir Makarenko, Manfred Jeitler, J A Chinellato et autres
Production fraction ratios of B$^+$, B$^0$, and B$^0_\mathrm{s}$ mesons are measured in proton-proton collisions at $\sqrt{s}$ = 13 TeV using a special data set recorded in 2018 with high-rate triggers designed to collect an unbiased sample of $10^{10}$ b hadrons with the …

Search for low-mass vector and scalar resonances decaying into a quark-antiquark pair in proton-proton collisions at $ \sqrt{s} = $ 13 TeV
Aram Hayrapetyan, Vladimir Makarenko, Priya Sajid Hussain, W De paula carvalho et autres
A search for resonances with masses from 50 to 300 GeV decaying into a quark-antiquark pair is presented. The search uses proton-proton collision data at $\sqrt{s}$ = 13 TeV collected by the CMS experiment at the CERN LHC in 2016$-$2018, corresponding to …

Highly boosted dielectron identification in proton-proton collisions at $ \sqrt{s} = $ 13 TeV
Aram Hayrapetyan, В. Макаренко, Manfred Jeitler, Helena Brandao Malbouisson et autres
A new technique is developed to identify dielectrons (e$^+$e$^-$) with Lorentz boost $γ_\mathrm{L}$$\gt$ 20 that produce one single merged cluster in the electromagnetic calorimeter of the CMS detector. The identification uses two multivariate models: one for the case where both electron tracks …

Search for the single production of vector-like quarks decaying into a W boson and a b quark using single-lepton final states in proton-proton collisions at $ \sqrt{s} = $ 13 TeV
Aram Hayrapetyan, Vladimir Makarenko, Manfred Jeitler, W De paula carvalho et autres
A search is performed for the single production of a heavy vector-like quark (VLQ), decaying into a W boson and a b quark. The analysis uses proton-proton collision data collected by the CMS experiment at the CERN LHC at a center-of-mass energy …

Search for electroweakinos in compressed-spectrum scenarios with low-momentum isolated tracks in proton-proton collisions at $ \sqrt{s} = $ 13 TeV
Aram Hayrapetyan, Vladimir Makarenko, Manfred Jeitler, Antonio Vilela Pereira et autres
A search for supersymmetric electroweakinos is performed using events with a low-momentum (soft) isolated track and large missing transverse momentum, targeting nearly mass-degenerate higgsino-like charginos and neutralinos. For mass splittings of 0.3$-$1 GeV, the chargino decays to the lightest neutralino and a …

Simultaneous measurements of $ N $-subjettiness observables in jets from gluons and light-flavour quarks, and in decays of boosted W bosons and top quarks
Aram Hayrapetyan, Vladimir Makarenko, N Krammer, Helena Brandao Malbouisson et autres
A simultaneous measurement of 25 substructure observables is presented using large-radius jets with high transverse momentum from proton-proton collisions at $\sqrt{s}$ = 13 TeV. The measurement is carried out on dijet events and $\mathrm{t\bar{t}}$ events enriched in Lorentz-boosted W bosons and top …

Search for pair production of additional neutral scalars within the Inert Doublet Model in a final state with two electrons or two muons in proton-proton collisions at $\sqrt{s}$ = 13 TeV and 13.6 TeV
Arzunik Gevorgyan, Aram Hayrapetyan, Manfred Jeitler, Clemencia Mora Herrera et autres
A first dedicated search for pair production of new scalars predicted by the Inert Doublet Model is performed using proton-proton collisions. Data were collected with the CMS detector at the CERN LHC at $\sqrt{s}$ = 13 TeV and 13.6 TeV, corresponding to …
