Search for heavy neutral Higgs bosons produced in association with b-quarks and decaying into b-quarks at ffiffi s p = 13 TeV with the ATLAS detector Aad, G. Atlas Collaboration, / Aguilar Saavedra, Juan Antonio A search for heavy neutral Higgs bosons produced in association with one or two b-quarks and decaying to b-quark pairs is presented using 27.8 fb−1 of ffiffi s p ¼ 13 TeV proton-proton collision data recorded by the ATLAS detector at the Large Hadron Collider during 2015 and 2016. No evidence of a signal is found. Upper limits on the heavy neutral Higgs boson production cross section times its branching ratio to bb¯ are set, ranging from 4.0 to 0.6 pb at 95% confidence level over a Higgs boson mass range of 450 to 1400 GeV. Results are interpreted within the two-Higgs-doublet model and the minimal supersymmetric Standard Model. 2020-09-28T12:26:54Z 2020-09-28T12:26:54Z 2020-08-13 journal article Aad, G., Abbott, B., Abbott, D.
