Search for a boosted Higgs boson decaying to bottom quark pairs in association with a W or Z boson in proton-proton collisions at s=13TeV

A Hayrapetyan, V Makarenko, A. Tumasyan, W. Adam et autres

A search is conducted for standard model Higgs bosons with large transverse momentum ( p T ) decaying to bottom quark pairs and produced in association with a hadronically decaying W or Z boson at the LHC. The result is based on …

Search for heavy long-lived charged particles with level-1 trigger scouting data from proton-proton collisions at s=13.6TeV

A Hayrapetyan, V Makarenko, A. Tumasyan, W. Adam et autres

A search for heavy long-lived charged particles at the LHC is presented. Particles traversing the CMS muon detector across several bunch crossings are searched for using a data sample of proton-proton collisions at s=13.6TeV collected with the CMS detector in 2024, corresponding …

High-level hadronic tau lepton triggers of the CMS experiment in proton-proton collisions at √(s) = 13.6 TeV

A Hayrapetyan, V Makarenko, A. Tumasyan, W. Adam et autres

Abstract The trigger system of the CMS detector is pivotal in the acquisition of data for physics measurements and searches. Studies of final states characterized by hadronic decays of tau leptons require the reconstruction and the identification of genuine tau leptons against …

Search for resonances decaying to an anomalous jet and a Higgs boson in proton–proton collisions at $$\sqrt{s}=13\,\text {Te}\hspace{-.08em}\text {V} $$

A Hayrapetyan, V Makarenko, A. Tumasyan, W. Adam et autres

Abstract This paper presents a search for new physics through the process where a massive particle, X, decays into a Higgs boson and a second particle, Y. The Higgs boson subsequently decays into a bottom quark–antiquark pair, which is reconstructed as a …

Model-independent measurement of the Higgs boson associated production with two jets and decaying to a pair of W bosons in proton-proton collisions at $ \sqrt{s}=13 $ TeV

CMS Collaboration, A Hayrapetyan, V Makarenko, A. Tumasyan et autres

A model-independent measurement of the differential production cross section of the Higgs boson decaying into a pair of W bosons, with a final state including two jets produced in association, is presented. In the analysis, events are selected in which the decay …

A measurement is presented of the electroweak vector boson scattering production of ZV (V = W, Z) boson pairs associated with two jets in proton-proton collisions at a center-of-mass energy of 13 TeV. The data, corresponding to an integrated luminosity of 138 …

Search for low-mass hidden-valley dark showers with non-prompt muon pairs in proton-proton collisions at $\sqrt{s}=13$ TeV

CMS Collaboration, A Hayrapetyan, V Makarenko, A. Tumasyan et autres

A search for signatures of a dark analog to quantum chromodynamics is performed. The analysis targets long-lived dark mesons that decay into standard-model particles, with a high branching fraction of the dark mesons decaying into muons. The dark mesons are formed by …
