Search for lepton-flavor violating decays of the Higgs boson in the μ τ and e τ final states in proton-proton collisions at s = 13 TeV

A. M. Sirunyan, A. Tumasyan, W. Adam, J. W. Andrejkovic et autres

A search is presented for lepton-flavor violating decays of the Higgs boson to $\ensuremath{\mu}\ensuremath{\tau}$ and $e\ensuremath{\tau}$. The dataset corresponds to an integrated luminosity of $137\text{ }\text{ }{\mathrm{fb}}^{\ensuremath{-}1}$ collected at the LHC in proton-proton collisions at a center-of-mass energy of 13 TeV. No …

Measurement of Bc(2S)+ and Bc*(2S)+ cross section ratios in proton-proton collisions at s=13 TeV

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

The ratios of the ${B}_{c}{(2S)}^{+}$ to ${B}_{c}^{+}$, ${B}_{c}^{*}{(2S)}^{+}$ to ${B}_{c}^{+}$, and ${B}_{c}^{*}{(2S)}^{+}$ to ${B}_{c}{(2S)}^{+}$ production cross sections are measured in proton-proton collisions at $\sqrt{s}=13\text{ }\text{ }\mathrm{TeV}$, using a data sample collected by the CMS experiment at the LHC, corresponding to an integrated …

Search for the pair production of light top squarks in the e±μ∓ final state in proton-proton collisions at $$ \sqrt{s}=13 $$ TeV

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

Abstract A search for the production of a pair of top squarks at the LHC is presented. This search targets a region of parameter space where the kinematics of top squark pair production and top quark pair production are very similar, because …

Search for new physics in final states with a single photon and missing transverse momentum in proton-proton collisions at $$ \sqrt{s}=13 $$ TeV

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

Abstract A search is conducted for new physics in final states containing a photon and missing transverse momentum in proton-proton collisions at $$ \sqrt{s}=13 $$ s = 13 TeV, using the data collected in 2016 by the CMS experiment at the LHC, …

Search for resonant pair production of Higgs bosons decaying to bottom quark-antiquark pairs in proton-proton collisions at 13 TeV

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

Abstract A search for a narrow-width resonance decaying into two Higgs bosons, each decaying into a bottom quark-antiquark pair, is presented. The search is performed using proton-proton collision data corresponding to an integrated luminosity of 35.9 fb−1at $$ \sqrt{s}=13 $$ s=13 TeV …

Search for a heavy resonance decaying into a Z boson and a vector boson in the $$ \nu \overline{\nu}\mathrm{q}\overline{\mathrm{q}} $$ final state

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

Abstract A search is presented for a heavy resonance decaying into either a pair of Z bosons or a Z boson and a W boson (ZZ or WZ), with a Z boson decaying into a pair of neutrinos and the other boson …

Measurement of the W boson helicity in events with a single reconstructed top quark in pp collisions at s = 8 $$ \sqrt{s}=8 $$ TeV

V. Khachatryan, A. M. Sirunyan, A. Tumasyan, W. Adam et autres

A measurement of the W boson helicity is presented, where the W boson originates from the decay of a top quark produced in pp collisions. The event selection, optimized for reconstructing a single top quark in the final state, requires exactly one …
