Search for resonant pair production of Higgs bosons decaying to bottom quark-antiquark pairs in proton-proton collisions at 13 TeV

TL;DR

This paper reports a search for a narrow resonance decaying into two Higgs bosons, each decaying to bottom quark pairs, using 13 TeV proton-proton collision data, setting upper limits on production cross sections.

Contribution

First search for a narrow resonance decaying into Higgs pairs in the bottom quark channel at 13 TeV with CMS data, establishing new upper limits.

Findings

No evidence for the resonance was observed.

Upper limits on cross section times branching fraction were set.

Resonance mass range explored from 260 to 1200 GeV.

Abstract

A search for a narrow-width resonance decaying into two Higgs bosons, each decaying into a bottom quark-antiquark pair, is presented. The search is performed using proton-proton collision data corresponding to an integrated luminosity of 35.9 fb$^{-1}$ at $\sqrt{s}=$ 13 TeV recorded by the CMS detector at the LHC. No evidence for such a signal is observed. Upper limits are set on the product of the production cross section for the resonance and the branching fraction for the selected decay mode in the resonance mass range from 260 to 1200 GeV.
