Search for pair production of scalar and vector leptoquarks decaying to muons and bottom quarks in proton-proton collisions at √s = 13 TeV
(2024)Physical Review DA search for pair production of scalar and vector leptoquarks (LQs) each decaying to a muon and a bottom quark is performed using proton-proton collision data collected at √s = 13 TeV with the CMS detector at the CERN LHC, corresponding to an integrated luminosity of 138 fb⁻¹. No excess above standard model expectation is observed. Scalar (vector) LQs with masses less than 1810 (2120) GeV are excluded at 95% confidence level, assuming a ...Journal Article -
Search for Baryon Number Violation in Top Quark Production and Decay Using Proton-Proton Collisions at √s = 13 TeV
(2024)Physical Review LettersA search is presented for baryon number violating interactions in top quark production and decay. The analysis uses data from proton-proton collisions at a center-of-mass energy of 13 TeV, collected with the CMS detector at the LHC with an integrated luminosity of 138 fb⁻¹. Candidate events are selected by requiring two oppositely charged leptons (electrons or muons) and exactly one jet identified as originating from a bottom quark. ...Journal Article -
Trapping in proton irradiated p+-n-n+ silicon sensors at fluences anticipated at the HL-LHC outer tracker
(2016)Journal of InstrumentationThe degradation of signal in silicon sensors is studied under conditions expected at the CERN High-Luminosity LHC. 200 μm thick n-type silicon sensors are irradiated with protons of different energies to fluences of up to 3 · 10¹⁵ neq/cm². Pulsed red laser light with a wavelength of 672 nm is used to generate electron-hole pairs in the sensors. The induced signals are used to determine the charge collection efficiencies separately for ...Journal Article -
Measurement of simplified template cross sections of the Higgs boson produced in association with W or Z bosons in the H → bb¯ decay channel in proton-proton collisions at √s = 13 TeV
(2024)Physical Review DDifferential cross sections are measured for the standard model Higgs boson produced in association with vector bosons (W, Z) and decaying to a pair of b quarks. Measurements are performed within the framework of the simplified template cross sections. The analysis relies on the leptonic decays of the W and Z bosons, resulting in final states with 0, 1, or 2 electrons or muons. The Higgs boson candidates are either reconstructed from pairs ...Journal Article
