Search for a light pseudoscalar Higgs boson in final states with boosted muon pairs and tau lepton pairs in proton-proton collisions at $\sqrt{s}$ = 13 TeV

Arzunik Gevorgyan, Aram Hayrapetyan, Vladimir Makarenko, Armen Tumasyan et autres

A search is presented for a light pseudoscalar Higgs boson, a, using LHC proton-proton data at $\sqrt{s}$ = 13 TeV collected by the CMS experiment from 2016 to 2018, corresponding to an integrated luminosity of 138 fb$^{-1}$. The analysis targets the process …

Search for the rare Higgs boson decay H $\to$ Z$γ$ in proton-proton collisions at $\sqrt{s}$ = 13 and 13.6 TeV

Arzunik Gevorgyan, Aram Hayrapetyan, Vladimir Makarenko, Armen Tumasyan et autres

A search is presented for the rare, loop-induced Higgs boson decay H $\to$ Z$γ$, where Z $\to$$\ell^+\ell^-$ and $\ell$ = e or $μ$. The search is performed using a sample of proton-proton (pp) collision data at the center-of-mass energies of 13 and …

Spin-dependent azimuthal asymmetry of coherent J/$ψ$ photoproduction in hadronic PbPb collisions at $\sqrt{s_\mathrm{NN}}$ = 5.36 TeV

Andrey Belyaev, Arzunik Gevorgyan, Aram Hayrapetyan, Armen Tumasyan et autres

We report a measurement of the azimuthal asymmetry of muons from the decay of coherently photoproduced J/$ψ$ mesons with respect to the second-order event plane in hadronic lead-lead (PbPb) collisions. The analysis is based on data collected by the CMS experiment at …

Constraint on the Higgs boson width in the diphoton final state using signal-background interference in proton-proton collisions at $ \sqrt{s}= $ 13 TeV

Arzunik Gevorgyan, Aram Hayrapetyan, Vladimir Makarenko, Armen Tumasyan et autres

The standard model Higgs boson, with a mass of 125 GeV, has a predicted decay width, $Γ_\mathrm{H}$, of 4.1 MeV. This Letter presents the first constraint on $Γ_\mathrm{H}$ obtained through the interference between the resonant H $\to$$γγ$ process and the continuum $γγ$ …

Observation of an excess at the top quark pair production threshold in the single-lepton channel

Arzunik Gevorgyan, Aram Hayrapetyan, Vladimir Makarenko, Armen Tumasyan et autres

A search is presented for top quark-antiquark ( $ \mathrm{t} \overline{\mathrm{t}} $) quasi-bound ``toponium'' states, near the kinematic $ \mathrm{t} \overline{\mathrm{t}} $ production threshold in final states with a single electron or muon and jets. The study uses proton-proton collision data at …

Observation of enhanced baryon production using strange hadrons in oxygen-oxygen collisions

Andrey Belyaev, Arzunik Gevorgyan, Aram Hayrapetyan, Armen Tumasyan et autres

A hot deconfined medium known as the quark-gluon plasma (QGP) is created in collisions of ultrarelativistic heavy nuclei. In these systems, hadron production is strongly modified relative to proton-proton (pp) interactions. In the hadron transverse momentum region 2 $ < p_{\mathrm{T}} < …
