Search for top squark pair production in a final state with two tau leptons in proton-proton collisions at √s = 13 TeV
(Springer Science and Business Media LLC, 2020)
© 2020, The Author(s). A search for pair production of the supersymmetric partner of the top quark, the top squark, in proton-proton collision events at s = 13 TeV is presented in a final state containing hadronically ...
Search for a low-mass τ−τ+ resonance in association with a bottom quark in proton-proton collisions at √s = 13 TeV
(Springer Science and Business Media LLC, 2019)
© 2019, The Author(s). A general search is presented for a low-mass τ−τ+ resonance produced in association with a bottom quark. The search is based on proton-proton collision data at a center-of-mass energy of 13 TeV ...
Studies of Beauty Suppression via Nonprompt D 0 Mesons in Pb-Pb Collisions at √ s NN = 5.02 TeV
(American Physical Society (APS), 2019)
© 2019 CERN. The transverse momentum spectra of D0 mesons from b hadron decays are measured at midrapidity (|y|<1) in pp and Pb-Pb collisions at a nucleon-nucleon center of mass energy of 5.02 TeV with the CMS detector at ...

Decomposing transverse momentum balance contributions for quenched jets in PbPb collisions at √sNN = 2.76 TeV
(Springer Nature, 2016-11)
Interactions between jets and the quark-gluon plasma produced in heavy ion collisions are studied via the angular distributions of summed charged-particle transverse momenta (p[subscript T]) with respect to both the leading ...
Search for pair-produced vectorlike B quarks in proton-proton collisions at √s = 8 TeV
(American Physical Society, 2016-06)
A search for the production of a heavy B quark, having electric charge −13 and vector couplings to W, Z, and H bosons, is carried out using proton-proton collision data recorded at the CERN LHC by the CMS experiment, ...
Measurement of b hadron lifetimes in pp collisions at √s = 8 TeV
(Springer Berlin Heidelberg, 2018-06)
Measurements are presented of the lifetimes of the B[superscript 0], B[superscript 0][subscript s], Λ[superscript 0][subscript b], and B[superscript +][superscript c] hadrons using the decay channels B[superscript ...
Search for long-lived particles that decay into final states containing two electrons or two muons in proton-proton collisions at √s = 8 TeV
(American Physical Society, 2015-03)
A search is performed for long-lived particles that decay into final states that include a pair of electrons or a pair of muons. The experimental signature is a distinctive topology consisting of a pair of charged leptons ...
Measurement of the underlying event activity using charged-particle jets in proton-proton collisions at √s = 2.76 TeV
(Springer-Verlag/SISSA, 2015-09)
A measurement of the underlying event (UE) activity in proton-proton collisions is performed using events with charged-particle jets produced in the central pseudorapidity region (|η[superscript jet]| < 2) and with transverse ...
Evidence for collectivity in pp collisions at the LHC
(Elsevier BV, 2017-02)
Measurements of two- and multi-particle angular correlations in pp collisions at √s=5, 7, and 13 TeV are presented as a function of charged-particle multiplicity. The data, corresponding to integrated luminosities of ...
