寻找13 TeV质子-质子碰撞中希格斯玻色子衰变到底夸克-反夸克对的共振对产生

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

CMS Collaboration

摘要:

研究了一种窄宽度共振衰变为两个希格斯玻色子玻色子,每个玻色子又衰变为一个底夸克-反夸克对。搜索是使用质子-质子碰撞数据进行的,对应于在$\sqrt{s}=$ 13 TeV的CMS探测器记录的35.9 fb $^{-1}$的积分亮度。没有观察到这种信号的证据。上限被设置在用于共振的产生截面和用于在从260至1200 GeV的共振质量范围内的所选衰变模式的分支分数的乘积上。

英文摘要:

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.
