Prospects for $t\bar{t} H$

The search for the Higgs boson is a major focus for the ATLAS and CMS experiments at the Large Hadron Collider. If the Higgs boson has a low mass ($m_H<130$\,GeV) then its production in association with a top quark pair could be observed. Searching for $t \bar{t} H$ signals is very challenging du...

Sumario:The search for the Higgs boson is a major focus for the ATLAS and CMS experiments at the Large Hadron Collider. If the Higgs boson has a low mass ($m_H<130$\,GeV) then its production in association with a top quark pair could be observed. Searching for $t \bar{t} H$ signals is very challenging due to a small signal cross section, large backgrounds, and a high number of jets in the final state. Here we review previous simulation studies of $t \bar{t} H (H \rightarrow b \bar{b})$. We show the current status of the major background measurement, $t \bar{t} +$jets. We outline recent improvements in theoretical predictions, Monte Carlo generators and jet reconstruction techniques that will enable us to perform this search in the near future.
