Search for low-mass resonances decaying into bottom quark-antiquark pairs in proton-proton collisions at s =13 TeV
A search for narrow, low-mass, scalar, and pseudoscalar resonances decaying to bottom quark-antiquark pairs is presented. The search is based on events recorded in ffiffi s p ¼ 13 TeV proton-proton collisions with the CMS detector at the LHC, collected in 2016, and corresponding to an integrated...

| description | A search for narrow, low-mass, scalar, and pseudoscalar resonances decaying to bottom quark-antiquark
pairs is presented. The search is based on events recorded in ffiffi
s p ¼ 13 TeV proton-proton collisions with
the CMS detector at the LHC, collected in 2016, and corresponding to an integrated luminosity of
35.9 fb−1. The search selects events in which the resonance would be produced with high transverse
momentum because of the presence of initial- or final-state radiation. In such events, the decay products of
the resonance would be reconstructed as a single large-radius jet with high mass and two-prong
substructure. A potential signal would be identified as a narrow excess in the jet invariant mass spectrum.
No evidence for such a resonance is observed within the mass range from 50 to 350 GeV, and upper limits
at 95% confidence level are set on the product of the cross section and branching fraction to a bottom quarkantiquark pair. These constitute the first constraints from the LHC on exotic bottom quark-antiquark
resonances with masses below 325 GeV. |
