Observation of Suppressed Charged-Particle Production in Ultrarelativistic Oxygen-Oxygen Collisions

Aram Hayrapetyan, В. Макаренко, A. Tumasyan, Wolfgang Adam et autres

A hot and dense state of nuclear matter, known as the quark-gluon plasma, is created in collisions of ultrarelativistic heavy nuclei. Highly energetic quarks and gluons, collectively referred to as partons, lose energy as they travel through this matter, leading to suppressed …

Dark sector searches with the CMS experiment

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

Astrophysical observations provide compelling evidence for gravitationally interacting dark matter in the universe that cannot be explained by the standard model of particle physics. The extraordinary amount of data from the CERN LHC presents a unique opportunity to shed light on the …

Search for a scalar or pseudoscalar dilepton resonance produced in association with a massive vector boson or top quark-antiquark pair in multilepton events at s=13 TeV

A. Tumasyan, W. Adam, J. W. Andrejkovic, T. Bergauer et autres

A search for beyond the standard model spin-0 bosons, ϕ , that decay into pairs of electrons, muons, or tau leptons is presented. The search targets the associated production of such bosons with a W or Z gauge boson, or a top …

Search for a W' boson decaying to a vector-like quark and a top or bottom quark in the all-jets final state at $\sqrt{s}$ = 13 TeV

A. Tumasyan, W. Adam, Janik Walter Andrejkovic, T. Bergauer et autres

A search is presented for a heavy W' boson resonance decaying to a B or T vector-like quark and a t or a b quark, respectively. The analysis is performed using proton-proton collisions collected with the CMS detector at the LHC. The …

Measurement of differential tt¯ production cross sections in the full kinematic range using lepton+jets events from proton-proton collisions at s=13 TeV

A. Tumasyan, W. Adam, Janik Walter Andrejkovic, T. Bergauer et autres

Measurements of differential and double-differential cross sections of top-quark pair ($t\overline{t}$) production are presented in the $\mathrm{lepton}+\text{jets}$ channels with a single electron or muon and jets in the final state. The analysis combines for the first time signatures of top quarks with …

Erratum to: Search for a new scalar resonance decaying to a pair of Z bosons in proton-proton collisions at s = 13 $$ \sqrt{s}=13 $$ TeV

A. M. Sirunyan, A. Tumasyan, W. Adam, F. Ambrogi et autres

In both panels of figure 11, the unit of the z axis was mistakenly written as “pb” when it should have been “fb”. The corrected versions are shown in figure 1.

Search for disappearing tracks as a signature of new long-lived particles in proton-proton collisions at $$ \sqrt{s}=13 $$ TeV

A. M. Sirunyan, A. Tumasyan, W. Adam, F. Ambrogi et autres

Abstract A search is presented for long-lived charged particles that decay within the CMS detector and produce the signature of a disappearing track. A disappearing track is an isolated track with missing hits in the outer layers of the silicon tracker, little …

Inclusive Search for a Highly Boosted Higgs Boson Decaying to a Bottom Quark-Antiquark Pair

A. M. Sirunyan, W. Adam, F. Ambrogi, E. Asilar et autres

An inclusive search for the standard model Higgs boson ($H$) produced with large transverse momentum (${p}_{\mathit{T}}$) and decaying to a bottom quark-antiquark pair ($b\overline{b}$) is performed using a data set of $pp$ collisions at $\sqrt{s}=13\text{ }\text{ }\mathrm{TeV}$ collected with the CMS experiment …
