Title: | Search for resonances decaying into photon pairs in 139 fb$^{-1}$ of $pp$ collisions at $\sqrt{s} =$ 13 TeV with the ATLAS detector | Authors: | Fiolhais, M. C. N. Gonçalo, R. Veloso, F. Wolters, H. ATLAS Collaboration |
Keywords: | High Energy Physics - Experiment; High Energy Physics - Experiment | Issue Date: | 26-Feb-2021 | Publisher: | Elsevier | Serial title, monograph or event: | Physics Letters, Section B: Nuclear, Elementary Particle and High-Energy Physics | Volume: | 822 | Abstract: | Searches for new resonances in the diphoton final state, with spin 0 as predicted by theories with an extended Higgs sector and with spin 2 using a warped extra-dimension benchmark model, are presented using 139 fb$^{-1}$ of $\sqrt{s} = $ 13 TeV $pp$ collision data collected by the ATLAS experiment at the LHC. No significant deviation from the Standard Model is observed and upper limits are placed on the production cross-section times branching ratio to two photons as a function of the resonance mass. | Description: | 33 pages in total, author list starting page 17, 5 figures, 2 tables, submitted to Physics Letters B.
