New ATLAS group paper

Collider Physics GroupThe paper “Search for a new scalar resonance in flavour-changing neutral-current top-quark decays 𝒕 → 𝒒𝑿 (𝒒 = 𝒖, 𝒄), with 𝑿 → 𝒃𝒃bar, in proton-proton collisions at sqrt(s) = 13 TeV with the ATLAS detector” has been submitted to JHEP.
The paper provides stringent limits of O(10e-4) on the production and decay of a scalar particle from 20 to 160 GeV in flavour-changing neutral current top quark decays. It is the first time this analysis is done in a collider experiment.
The main authors are from IFAE and are Adrian Salvador, Martine Bosman, Aurelio Juste, Lluïsa Mir, Nicola Orlando and Imma Riu.
