Several models beyond the Standard Model predict heavy particles decaying
to b jets. This poster presents the searches for resonances in the di-jet
invariant mass spectrum with one or two jets identified as b-jets. The
search is performed using proton–proton collisions data with a
centre-of-mass energy of 13 TeV recorded by the ATLAS detector in the years
2015 and 2016 at the Large Hadron Collider.
