Search for heavy resonances decaying to a $Z$ boson and a photon in $pp$ collisions at $\sqrt{s}=13$ TeV with the ATLAS detector
This note describes a search for new resonances with mass larger than 250 GeV, decaying to a $Z$ boson and a photon. The dataset consists of 3.2 fb$^{-1}$ of $pp$ collisions collected at $\sqrt{s} = 13$~TeV with the ATLAS detector at the Large Hadron Collider. The $Z$ bosons are identified through t...

Sumario: | This note describes a search for new resonances with mass larger than 250 GeV, decaying to a $Z$ boson and a photon. The dataset consists of 3.2 fb$^{-1}$ of $pp$ collisions collected at $\sqrt{s} = 13$~TeV with the ATLAS detector at the Large Hadron Collider. The $Z$ bosons are identified through their decays either to charged, light lepton pairs ($e^+e^-$, $\mu^+\mu^-$) or to hadrons. The data are consistent with the expected background in the whole mass range investigated and upper limits are set on the production cross section times decay branching ratio to $Z\gamma$ of a narrow scalar boson with mass between 250 GeV and 2.75 TeV. |
