چکیده
A search for a standard model Higgs boson produced in association with a top-quark pair and decaying to bottom quarks is presented. Events with hadronic jets and one or two oppositely charged leptons are selected from a data sample corresponding to an integrated luminosity of 19.5[Formula: see text] collected by the CMS experiment at the LHC in [Formula: see text] collisions at a centre-of-mass energy of 8[Formula: see text]. In order to separate the signal from the larger [Formula: see text] + jets background, this analysis uses a matrix element method that assigns a probability density value to each reconstructed event under signal or background hypotheses. The ratio between the two values is used in a maximum likelihood fit to extract the signal yield. The results are presented in terms of the measured signal strength modifier, [Formula: see text], relative to the standard model prediction for a Higgs boson mass of 125[Formula: see text]. The observed (expected) exclusion limit at a 95 % confidence level is [Formula: see text] (3.3), corresponding to a best fit value [Formula: see text].

متن کاملSearch for dark matter produced in association with a Higgs boson
This article reports on a search for dark matter pair production in association with a Higgs boson decaying to a pair of bottom quarks, using data from 20.3 fb−1 of pp collisions at a center-of-mass energy of 8 TeV collected by the ATLAS detector at the LHC. The decay of the Higgs boson is reconstructed as a high-momentum bb̄ system with either a pair of small-radius jets, or a single large-radi...
متن کاملPossibilities of tt̄H Event Reconstruction
A light Standard Model Higgs boson can be produced in association with tt̄ in the process pp → tt̄H and detected in the final state bb̄bb̄qq̄lν. The cross section of this channel is not large, but there are only few sources of Standard Model background with similar event structures. Here we investigate how the correct b jets can be selected in view of H mass reconstruction. We discuss three methods ...
متن کاملSearch for the standard model Higgs boson produced through vector boson fusion and decaying to bb̄
A first search is reported for a standard model Higgs boson (H) that is produced through vector boson fusion and decays to a bottom-quark pair. Two data samples, corresponding to integrated luminosities of 19.8 inverse femtobarns and 18.3 inverse femtobarns of proton-proton collisions at √ s = 8 TeV were selected for this channel at the CERN LHC. The observed significance in these data samples ...

The production of a light Standard Model Higgs boson in association with a top-quark pair at the Large Hadron Collider (LHC) is studied in a simulation of the multipurpose ATLAS experiment. The Higgs boson is assumed to decay into a bb̄ pair, and the top-quark pair to decay semi-leptonically. The main background process for this channel is the production of tt̄ events, which can be divided into r...
