The elusive gluon

We study the phenomenology of vector resonances in the context of natural composite Higgs models. A mild hierarchy between the fermionic partners and the vector resonances can be expected in these models based on the following arguments. Both direct and indirect (electroweak and flavor precision) constraints on fermionic partners are milder than the ones on spin one resonances...

Boosting the standard model Higgs signal with the Template Overlap Method

We show that the Template Overlap Method can improve the signal to background ratio of boosted h → \( b\overline{b} \) events produced in association with a leptonically decaying W. We introduce several improvements on the previous formulations of the template method. Varying three-particle template subcones increases the rejection power against the backgrounds, while the...

Measuring boosted tops in semi-leptonic \( t\overline{t} \) events for the standard model and beyond

Abstract We present a procedure for tagging boosted semi-leptonic \( t\overline{t} \) events based on the Template Overlap Method. We introduce a new formulation of the template overlap function for leptonically decaying boosted tops and show that it can be used to compensate for the loss of background rejection due to reduction of b-tagging efficiency at high p T . A study of...
