Search for b -hadron decays to long-lived particles in the CMS endcap muon detectors

Aram Hayrapetyan, Vladimir Makarenko, A. Tumasyan, W. Adam et autres

A search for long-lived particles originating from the decay of b hadrons produced in proton-proton collisions with a center-of-mass energy of 13 TeV at the LHC is presented. The analysis is performed on a dataset recorded in 2018, corresponding to an integrated …

Flavour and precision probes of a class of scotogenic models

A. Darricau, Haneol Lee, Jean Orloff, A. M. Teixeira

We address the phenomenological impact of a well-motivated class of scotogenic models regarding flavour and electroweak precision observables. For the case of a ``T1-2-A'' variant, we carry out a full computation of the next-to-leading order corrections to leptonic Higgs and $Z$-boson decays. …

Observation of long-range collective flow in OO and NeNe collisions and implications for nuclear structure studies

Vladimir Makarenko, A. Tumasyan, Wolfgang Adam, L. Benato et autres

The long-range collective flow of particles produced in oxygen-oxygen (OO) and neon-neon (NeNe) collisions is measured with the CMS detector at the CERN LHC. The data samples were collected at a center-of-mass energy per nucleon pair of 5.36 TeV, with integrated luminosities …

Search for heavy pseudoscalar and scalar bosons decaying to a top quark pair in proton-proton collisions at $\sqrt{s}$ = 13 TeV

Vladimir Makarenko, A. Tumasyan, Wolfgang Adam, Janik Walter Andrejkovic et autres

A search for pseudoscalar or scalar bosons decaying to a top quark pair (${\text{t}}\bar{\text{t}}$) in final states with one or two charged leptons is presented. The analyzed proton–proton collision data was recorded at $\sqrt{s} = 13\,\textrm{TeV}$ by the CMS experiment at the …

Observation of quantum entanglement in top quark pair production in proton–proton collisions at s=13 TeV

Aram Hayrapetyan, A. Tumasyan, Wolfgang Adam, Janik Walter Andrejkovic et autres

Abstract Entanglement is an intrinsic property of quantum mechanics and is predicted to be exhibited in the particles produced at the Large Hadron Collider. A measurement of the extent of entanglement in top quark-antiquark ( tt¯ ) events produced in proton–proton collisions …

Measurement of boosted Higgs bosons produced via vector boson fusion or gluon fusion in the H $\to$$\mathrm{b\bar{b}}$ decay mode using LHC proton-proton collision data at $\sqrt{s}$ = 13 TeV

Aram Hayrapetyan, A. Tumasyan, W. Adam, Janik Walter Andrejkovic et autres

A measurement is performed of Higgs bosons produced with high transverse momentum ($p_\mathrm{T}$) via vector boson or gluon fusion in proton-proton collisions. The result is based on a data set with a center-of-mass energy of 13 TeV collected in 2016-2018 with the …
