Mechanical stability of the CMS strip tracker measured with a laser alignment system

A. M. Sirunyan, A. Tumasyan, W. Adam, E. Asilar et autres

The CMS tracker consists of 206 $m^2$ of silicon strip sensors assembled on carbon fibre composite structures and is designed for operation in the temperature range from −25 to +25°C. The mechanical stability of tracker components during physics operation was monitored with …

Search for electroweak production of charginos and neutralinos in WH events in proton-proton collisions at √s=13 TeV

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

Results are reported from a search for physics beyond the standard model in proton-proton collision events with a charged lepton (electron or muon), two jets identified as originating from a bottom quark decay, and significant imbalance in the transverse momentum. The search …

Measurement of charged pion, kaon, and proton production in proton-proton collisions at $\\sqrt{s}=13$ TeV

A. M. Sirunyan, A. Tumasyan, W. Adam, E. Asilar et autres

Transverse momentum spectra of charged pions, kaons, and protons are measured in proton-proton collisions at $\sqrt{s}$ = 13 TeV with the CMS detector at the LHC. The particles, identified via their energy loss in the silicon tracker, are measured in the transverse …
