Search for resonances in the mass spectrum of muon pairs produced in association with b quark jets in proton-proton collisions at s√=8 and 13 TeV
(Springer Nature, 2018-11)
A search for resonances in the mass range 12–70 GeV produced in association with a b quark jet and a second jet, and decaying to a muon pair, is reported. The analysis is based on data from proton-proton collisions at ...
Computer simulations of 4240 MOF membranes for H2/CH4 separations: insights into structure–performance relations
(Royal Society of Chemistry, 2018-04-14)
Design of new membranes having high H2/CH4 selectivity and high H2 permeability is strongly desired to reduce the energy demand for H2 production. Metal organic frameworks (MOFs) offer a great promise for membrane-based ...
Search for vectorlike light-flavor quark partners in proton-proton collisions at √s=8 TeV
(American Physical Society., 2018-04-11)
A search is presented for heavy vectorlike quarks (VLQs) that couple only to light quarks in proton-proton collisions at root s = 8 TeV at the LHC. The data were collected by the CMS experiment during 2012 and correspond ...
Suppression of excited Υ states relative to the ground state in Pb-Pb collisions at √sNN =5.02 TeV
(American Physical Society, 2018-04-02)
The relative yields of gamma mesons produced in pp and Pb-Pb collisions at root s(NN) = 5.02 TeV and reconstructed via the dimuon decay channel are measured using data collected by the CMS experiment. Double ratios are ...
Database for CO2 separation performances of MOFs based on computational materials screening
(American Chemical Society, 2018-05-23)
Metal-organic frameworks (MOFs) are potential adsorbents for CO2 capture. Because thousands of MOFs exist, computational studies become very useful in identifying the top performing materials for target applications in a ...
Measurement of jet substructure observables in t¯t events from proton-proton collisions at √s = 13 TeV
(American Physical Society, 2018-11-29)
A measurement of jet substructure observables is presented using tt events in the lepton+jets channel from proton-proton collisions at s=13 TeV recorded by the CMS experiment at the LHC, corresponding to an integrated ...
Search for an exotic decay of the Higgs boson to a pair of light pseudoscalars in the final state with two b quarks and two τ leptons in proton–proton collisions at √s=13 TeV
(Elsevier, 2018-10-10)
A search for an exotic decay of the Higgs boson to a pair of light pseudoscalar bosons is performed for the first time in the final state with two b quarks and two τ leptons. The search is motivated in the context of models ...
Performance of reconstruction and identification of τ leptons decaying to hadrons and vτ in pp collisions at √s=13 TeV
(IOP Publishing, 2018-10)
The algorithm developed by the CMS Collaboration to reconstruct and identify tau leptons produced in proton-proton collisions at root s = 7 and 8 TeV, via their decays to hadrons and a neutrino, has been significantly ...
Observation of the Z → ψ ℓ + ℓ − decay in pp collisions at √s = 13 TeV
(American Physical Society, 2018-10-04)
This Letter presents the observation of the rare Z boson decay Z→ψ + -. Here, ψ represents contributions from direct J/ψ and ψ(2S)→J/ψX, + - is a pair of electrons or muons, and the J/ψ meson is detected via its decay to ...
Constraints on models of scalar and vector leptoquarks decaying to a quark and a neutrino at √s = 13 TeV
(American Physical Society, 2018-08-10)
The results of a previous search by the CMS Collaboration for squarks and gluinos are reinterpreted to constrain models of leptoquark (LQ) production. The search considers jets in association with a transverse momentum ...
