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 …

Search for exotic Higgs boson decays H $\to$$\mathcal{AA}$ with $\mathcal{AA}$$\to$$γγ$ in events with a semi-merged topology in proton-proton collisions at $\sqrt{s}$ = 13 TeV

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

A search for exotic Higgs boson decays H $\to$$\mathcal{AA}$, with $\mathcal{A}$$\to$$γγ$ is presented, using events with a semi-merged topology. One of the hypothetical particles, $\mathcal{A}$, is assumed to decay promptly into a semi-merged diphoton system reconstructed as a single photon-like object, while …

Measurement of W W Z and Z H Production Cross Sections at s = 13 and 13.6 TeV

В. Макаренко, A. Tumasyan, W. Adam, J W Andrejkovic et autres

A measurement is presented of the cross section in proton-proton collisions for the production of two W bosons and one Z boson. It is based on data recorded by the CMS experiment at the CERN LHC at center-of-mass energies sqrt[s]=13 and 13.6 …

Beam test performance studies of CMS Phase-2 Outer Tracker module prototypes

W. Adam, T. Bergauer, K. Damanakis, M. Dragicevic et autres

Abstract A new tracking detector will be installed as part of the Phase-2 upgrade of the CMS detector for the high-luminosity LHC era. This tracking detector includes the Inner Tracker, equipped with silicon pixel sensor modules, and the Outer Tracker, consisting of …

Measurement of the fractional radiation length of a pixel module for the CMS Phase-2 upgrade via the multiple scattering of positrons

W. Adam, T. Bergauer, K. Damanakis, M. Dragicevic et autres

Abstract High-luminosity particle collider experiments such as the ones planned at the High-Luminosity Large Hadron Collider require ever-greater vertexing precision of the tracking detectors, necessitating reductions in the material budget of the detectors. Traditionally, the fractional radiation length (x/X 0) of detectors …

Evaluation of planar silicon pixel sensors with the RD53A readout chip for the Phase-2 Upgrade of the CMS Inner Tracker

W. Adam, T. Bergauer, K. Damanakis, M. Dragicevic et autres

Abstract The Large Hadron Collider at CERN will undergo an upgrade in order to increase its luminosity to 7.5 × 1034 cm-2s-1. The increased luminosity during this High-Luminosity running phase, starting around 2029, means a higher rate of proton-proton interactions, hence a …
