Search for flavor changing neutral current interactions of the top quark in final states with a photon and additional jets in proton-proton collisions at s=13 TeV

Aram Hayrapetyan, A. Tumasyan, W. Adam, Janik Walter Andrejkovic et autres

A search for the production of a top quark in association with a photon and additional jets via flavor changing neutral current interactions is presented. The analysis uses proton-proton collision data recorded by the CMS detector at a center-of-mass energy of 13 …

Search for medium effects using jets from bottom quarks in PbPb collisions at $\sqrt{sNN}$ =5.02 TeV

A. Tumasyan, W. Adam, J. W. Andrejkovic, T. Bergauer et autres

The first study of the shapes of jets arising from bottom (b) quarks in heavy ion collisions is presented. Jet shapes are studied using charged hadron constituents as a function of their radial distance from the jet axis. Lead-lead (PbPb) collision data …

Search for Flavor-Changing Neutral Currents in Top-Quark Decays tZq in pp Collisions at sqrt[s]=8TeV.

A search for flavor-changing neutral currents in top-quark decays $t\to Zq$ is performed in events produced from the decay chain $t\overline{t}\to Zq+Wb$, where both vector bosons decay leptonically, producing a final state with three leptons (electrons or muons). A data set collected …
