Search for a new pseudoscalar decaying into a pair of bottom and antibottom quarks in top-associated production in $$\sqrt{s}=13$$ s = 13  TeV proton–proton collisions with the ATLAS detector

Abstract A search for a pseudoscalar a produced in association with a top-quark pair, or in association with a single top quark plus a W boson, with the pseudoscalar decaying into b-quarks ( $$a\rightarrow b\bar{b}$$ a → b b ¯ ), is performed using the full Run 2 data sample using a dileptonic decay...
